It dives into the various and necessary factors that need to be considered for a stable and efficient solar structural building to be constructed. It not only guides us in ensuring a safe and efficient design but it also enlightens us on the ways daylight plays a crucial role in our lives. As living in harmony with the environment is a necessary consideration, we will also be delving into the environmental factors that affect our architectural design, such as the amount of light penetration needed in the structure, the orientation of the structure to get the most amount of light, various ways to control the light intake, the proper positioning of the windows and the interior design to maximize the natural light.Tétel Korlátozottan hozzáférhető Structural check of the multi-aile hall buildingVarta, Amirreza; Radnay, Laszlo; DE--Műszaki KarThis thesis analyzes an existing hall building after the addition of a flat-roof extension and two dominant openings, which required new load calculations due to the loss of structural symmetry. The structure was re-evaluated for internal forces, stiffness, joint connections, imperfections, seismic actions, fire design, and buckling behavior. The results confirm that the main structure can safely support the new extension and satisfies the required safety and performance criteria.Tétel Korlátozottan hozzáférhető Effect of Roof Bracing on the Structural Performance of a Steel Hall with Low-Stiffness ConnectionsAkhtar, Sufian; Laszlo, Radnay; DE--Műszaki KarModern industrial and recreational buildings are often realized in steel because it offers strength, speed of erection and a lightweight envelope. However, when the structure must accommodate a corrosive and humid environment, such as a public swimming pool, designers must balance material efficiency with durability and safety. My thesis investigates this balance by designing a short steel hall with low-stiffness beam–column connections and examining how the introduction of roof bracing affects its structural performance. The case study is a 22 m by 15 m hall consisting of five portal frames set 5.5 m apart. The 10° pitched roof is supported by HEA 260 interior columns and HEA 180 corner columns; intermediate rafters vary between IPE 330 and IPE 240 profiles, while the longitudinal beams are SHS 70×70×3 tubes. Cross-shaped bracing bars of Ø16 mm steel connect the purlins at the gable walls and across the roof plane. This configuration was analysed in AxisVM using the Eurocode suite and the Hungarian National Annex. Permanent loads included the self-weight of the steelwork, roof cladding and pool deck; variable actions comprised snow, wind, temperature, seismic and accidental fire loads. Both linear and geometric-nonlinear analyses were performed, and the semi-rigid connections were checked against Eurocode 3 rules. Two structural models were studied. The first omitted roof bracing and relied solely on portal action to resist horizontal loads. The second introduced roof and end-wall bracing, thereby tying the frames together. The results of the first-order and second-order analyses showed that the braced model had significantly greater lateral stiffness and smaller internal forces in the intermediate frames. Whereas the unbraced hall required larger sections (IPE 360, HEA 300, IK 480) and still approached serviceability limits, the braced hall achieved acceptable deflections with the smaller HEA 260 and HEA 180 columns and variable IPE 330 rafters. Overall steel weight fell from about 13 t in the unbraced model to 8.6 t in the braced one, translating into lower material costs and a smaller surface area exposed to the corrosive pool atmosphere. The roof bracing also allowed the beam–column connections to be treated as nominally pinned, simplifying fabrication and reducing bolting demands. Dynamic analysis using the response spectrum method showed that the fundamental vibration modes of the braced hall were around 2.5 Hz and that seismic actions in the X and Y directions produced modest displacements well within Eurocode 8 limits. Imperfection loads applied in both axes demonstrated that the second-order effects were small thanks to the bracing. A fire design assessment, based on the ISO 834 curve and section factors, indicated that most members could withstand 15 minutes of standard-fire exposure without protection; only a few SHS 70×70×3 braces approached their critical temperature and would benefit from a thin intumescent coating or a slightly thicker tube. By combining rigorous analysis with practical design decisions, this thesis illustrates how a thoughtfully detailed bracing system can unlock substantial material savings and performance improvements in a low-stiffness steel hall. The findings support the use of roof bracing in single-storey structures where economic efficiency and serviceability are priorities and provide a template for future designs in similarly demanding environment.Tétel Korlátozottan hozzáférhető Design of a Timber Structure Museum in MongoliaBazar, Misheelt; Zoltan, Bereczki; DE--Műszaki KarThis thesis explores the design of a contemporary art museum using engineered timber construction, with a primary focus on the development of coordinated architectural and structural drawings. The project reinterprets heritage-inspired timber spatial principles through a modern glue-laminated timber structural system to achieve large open exhibition spaces and structural clarity. Structural layouts are developed in accordance with Eurocode design principles, ensuring rational load paths, serviceability performance, and material efficiency. Preliminary numerical verification using AxisVM confirms the feasibility and structural safety of the proposed roof system. The study demonstrates that large-scale timber buildings can be structurally safe, durable, and sustainable, combining historical precedent with contemporary engineering practice.Tétel Korlátozottan hozzáférhető Contemporary domes structures: case studies from KazakhstanAssan, Didar; Bereczki, Zoltán; DE--Műszaki KarThis thesis project is designed to undertake a comparative analysis and evaluation of large dome constructions in Central Asia, comparing with their European counterparts. The study aims to assess the efficiency of constructing large domes by examining structural challenges, behavioural characteristics, and detailed interpretations through top-view, cross-sectional, and detailed interpretations. Going into these aspects, this contemporary research aims to establish a foundational understanding for the design, construction, and maintenance of large domes. Furthermore, it is expected that this study will serve as a valuable resource for future researchers in similar projects, providing guidance for their implementation and development.Tétel Korlátozottan hozzáférhető Carbon Footprint Assessment of Restaurant: A Case Study in Debrecen, HungarySanthad, Nichanan; Pataki, Beáta; DE--Műszaki KarThe objective of this study is to assess and identify the hotspots of greenhouse gas (GHG) emissions from a restaurant in Debrecen. The study employed concepts of life cycle assessment to evaluate and analyze the carbon footprint from a sample of restaurants using purposive selection. Emission activities assessment covered the processes of food preparation, cooking, dining-in, and waste generation. Greenhouse gas emissions were categorized into three types: 1) Direct GHG emissions, 2) Energy Indirect GHG emissions, and 3) Other Indirect GHG emissions. The results from the sample restaurant revealed a total GHG emission of 40,695.15 kgCO2e/year. The hotspot activities with the highest emissions in the sample restaurant were the use of electrical energy, which accounted for 71% of the total emissions, followed by organic waste and packaging at 18% and 6%, respectively.Tétel Korlátozottan hozzáférhető Urban Morphology Analysis of Informal Settlements in Bogota, Colombia: Towards Enhanced Urban ResiliencePalacios, Paula; Lovra, Eva; DE--Műszaki KarThe aim of the present research is to introduce and analyze the urban and architectural patterns of informal settlements from two examples located in Bogota. To provide accurate solutions and time sustainable proposals for the cities, it is necessary for urban planners and professionals to obtain key information and have a comprehensive understanding of the trends and realities occurring in them.Tétel Korlátozottan hozzáférhető Rebuilding Post-conflict Cities through the lens of Spatial Justice, Case study: Barzeh and Al-QabounSkiker, Afraa; Bereczki, Zoltán; DE--Műszaki KarThis thesis explores the absence of justice when preparing Urban plans for Damascus City, focusing on the widespread slums, particularly in the eastern areas. The region is crucial as the main gateway to the east entrance of the capital, which has endured substantial damage, destruction, and population displacement due to the Syrian crisis. The research aims to identify the urban planning approach employed by the government, based on legislative frameworks, through an analysis of pre-crisis plans for the Barzeh and Qaboun regions and a detailed study of the proposed post-conflict plan for Qaboun. The Key Findings: Urban Planning Approach: The government’s approach to urban planning has systematically excluded local communities from decision-making and regional organization processes. This exclusion has led to significant violations of human rights and property rights, particularly evident in the Qaboun region. Legislative Gaps: The government-approved legislative framework has a significant gap in it and is unclear, exacerbating spatial justice problems. Community Involvement: The study developed tools to measure local community intervention and the type of urban application employed. The findings indicate that excluding local community involvement in urban planning leads to pronounced spatial injustice. Conclusion: The analysis of the current situation in the Barzeh and Qaboun regions suggests that the government’s exclusionary approach results in significant spatial injustice. This approach has caused human rights violations and property rights infringements. The study highlights the necessity for a more inclusive and transparent legislative framework to ensure equitable urban development in post-conflict settings. By examining the relationship between spatial justice, urban planning practices, and the role of local communities, this thesis offers valuable insights into the fairness and effectiveness of post-conflict reconstruction efforts in Damascus.Tétel Korlátozottan hozzáférhető Development of public transportation system in order to achieve sustainable transportation in IsfahanTaheri, Saheleh; György , Csomós; DE--Műszaki KarSustainable public transportation is crucial for urban planning due to rising urbanization and increased transportation demands. Sustainable systems aim to balance economic, social, and environmental needs by creating efficient networks, reducing pollution, and using clean energy. These systems enhance quality of life, promote environmental conservation, and ensure intergenerational fairness. Key features include minimal environmental impact, diverse mobility options, economic support, and operational efficiency. Indicators to evaluate these systems cover economic, social, and environmental aspects, such as employment rates, income distribution, resource consumption, and public health. Strategies for sustainable transportation include coordinating land use with transit planning, revitalizing urban centers, and improving transit services. Implementing innovative solutions and addressing current weaknesses can foster livable cities that maintain high living standards while protecting the environment for future generations.Tétel Korlátozottan hozzáférhető Urban Evolution: Muscat Transit to Fifteen Minutes CityAl Kindi, Salim; Bereczki, Zoltán; DE--Műszaki KarThe research aims to analyze various neighborhoods in Muscat, Oman, to identify factors contributing to achieving a 15-minute city or a 20-minute suburb. This study utilizes multiple methods to analyze the area comprehensively and proposes design improvements to enhance the neighborhood's functionality and livability.Tétel Korlátozottan hozzáférhető Informal architecture: Low cost, easy to construct structuresJabrayilzada, Ahad; Zoltan, Bereczki; DE--Műszaki KarIn this thesis, we went through an analysis regarding informality in different regions and checked what is the role, benefit, or damage it is causing to its society. Focus of this study is on how and what materials were utilized to build the villages. Considering, now we are living in a much more demanding and high standards filled society, the current world economy, the population, and resources are not enough to remove or suspend informality found in cities, suburbs, and urban places. Most people are still accustomed to living on a tight budget, informal settlements abound, particularly in and near rural areas. Therefore, we tried to illustrate slums that actually are either the combination of a simple design whilst it is eligible to carry a different role while as small change necessary as possible, while also achieving great variability with a limited number of elements.Tétel Korlátozottan hozzáférhető Investigation of Mausoleum of Khoja Ahmed Yasawi, Turkistan, focusing on load bearing parts and damagesAlimbay, Aziz; Bereczki, Zoltán; DE--Műszaki KarThis study focuses on the investigation of the Mausoleum of Khoja Ahmed Yassawi, with a specific emphasis on its loadbearing components and existing damages. Through an examination, we identified structural issues, documented architectural features, and conducted basic structural analyses to assess the condition of critical elements such as domes and arches. The comprehensive findings provide a baseline for future analyses and preservation efforts. Notably, despite visible damages, ongoing restoration work demonstrates a collective commitment to safeguarding this historical architectural heritage. The study concludes with recommendations for advanced research, materials analysis, long-term monitoring, and collaborative initiatives to ensure the continued preservation of this significant cultural landmark.Tétel Korlátozottan hozzáférhető Design of a hall building with monopitch roofShi, Weimeng; Radnay, László; DE--Műszaki KarThe purpose of this paper is to design and use the relevant computer software tools for building with monopitch roof, based on the Eurocode standard.

These occur due to many reasons for example natural causes like wild fires and natural disasters like lightning. They also occur due to man-made causes which mostly end up happening in some sort of structure like a house, an office or a factory. These fire accidents can lead to the loss of lives, expen- sive equipment and collapse of structures that can even lead to more loss of life. This shows how important it is for us civil engineers to design for this accident just as much as we design when it comes to wind accidents or snow accidents that cause the collapse of a global structure or a specific part of the structure. That is why in this project, I will be making as much research as I can in the ensuring of structural safety of an office building. I will first start by understanding what fire is and its various causes, look into its various relations with common building materials like concrete and steel and then finally do fire design for the material structures.Tétel Korlátozottan hozzáférhető DESIGN OF A RESIDENTIAL HOME AND ANALYSIS OF THE ROOF STRUCTURE ACCORDING TO THE EUROCODEOteng Duah, Nana Wiafe; Igaz, Titusz; DE--Műszaki KarDesign of a residential home starts with an understanding of the owner’s needs, preferences, and lifestyle.
