Master Thesis Evaluation of Behaviour Factors of Steel Moment Resisting Frames(Izmir Institute of Technology, 2019) Baran, İbrahim; Aktaş, Engin; Aktaş, Engin; Kanyılmaz, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyBuilders of structures throughout the history of civilizations have been challenged with various threats. Earthquakes, which may be considered as the most critical challenge of the built environment have been one of the main concerns of builders at all times especially in regions with high earthquake risk. In this study, Response Modification Factor, (also known as ‘R’ or ‘q’ factor) which is used by seismic codes to determine force demand considering the ductile behaviour of the structure during the earthquake, has been analyzed. Steel frames (36 frames) with a different number of stories (3,6,9) and bays (3 to 8) were designed with normal ductility (18 frames) and high ductility (18 frames) moment resisting steel frames. The Turkish Building Earthquake Code-2018 (TBEC 2018) was followed for the seismic design process. All frames were assumed to be constructed in a region with the highest seismic demand defined in the web-based Hazard Map in TBEC 2018. The performance evaluation of the designed frames is completed using non-linear static analyses following FEMA, ATC-40 and NEHRP guidelines. The non-linear static analyses were implemented with SAP2000 v20.2 commercial software. Static pushover analysis as well as the capacity curve graph, known as the N2 method, has been obtained, and the position of the frame capacity in the spectral acceleration graph has been determined and presented visually. The results were summarized and the R factors obtained from these analyses were compared with the values given in the Turkish Building Earthquake Code.Master Thesis Project Plannig and Management Using Building Information Modeling (bim)(Izmir Institute of Technology, 2018) Politi, Ruti Ruth; Aktaş, Engin; İlal, Mustafa Emre; Aktaş, Engin; İlal, Mustafa Emre; 02.02. Department of Architecture; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology; 02. Faculty of ArchitectureToday, in construction practice, implementation of effective construction management techniques and tools is becoming essential, especially as the scale of the projects increases. Large scale projects pose a challenge to industry; as the number of tasks, parameters and constraints to be considered rises, interaction of these tasks and parameters increases the complexity, as well. While the search for techniques and tools for better coping with complexity will never end, Building Information Modeling (BIM) has recently emerged as an approach that achieves considerable improvement in efficiently handling complexity. BIM is able to provide a digital visualization of a building or structure in 3D. The necessary geometric data is modeled but more importantly all semantic data associated with the project (function of the element, material properties, construction details, schedules, etc.) is stored with the model. The intent is to have a single model of the project for all stakeholders over all phases of the project. In this study, the main challenges within the current practice of project management are analyzed and what BIM-based project management has to offer to those challenges have been discussed. The thesis explores how BIM method can be applied to project management and how information can be collected to build a BIM model. The advantages of BIM-based scheduling (4D), cost estimation (5D), sustainability (6D), facility management (7D) and structural analysis in the scope of project management is discussed. A case study is given to validate the use of the computer aided programs for nD BIM during the construction phase.
