Energy based seismic assessment and design Alıcı, Fırat Soner; Sucuoğlu, Haluk; Erberik, Murat Altuğ; Department of Civil Engineering (2019) The need to improve the reliability of current earthquake resistant design procedures has promoted energy-based concepts that employ seismic input energy and energy dissipation capacity of structures as the main design tools. Energy based approaches provide effective tools at both design and assessment stages for a comprehensive interpretation of the seismic behavior of structural systems during an earthquake excitation. Energy based assessment and design procedure includes two crucial aspects. The first on...
Use of simulated strong ground motion records in earthquake engineering applications Karimzadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2016) With the recent advances in scientific computing, ground motion simulations have become more common. However, use of simulated motions for earthquake engineering purposes is still not well investigated. In this thesis, the efficiency of records simulated with the stochastic finite-fault technique in seismic demand estimation is studied in two different earthquake engineering applications. First, vulnerability assessment in a selected region, Erzincan (Turkey) is performed with simple single-degree-of-freedo...
Assessment of nonlinear static (pushover) analysis procedures using field experience Dilsiz, Abdullah; Gülkan, Polat; Yakut, Ahmet; Department of Civil Engineering (2013) Recently, many nonlinear analysis procedures have been proposed for earthquake response determination of the structures. Although, the nonlinear response history analysis (NRHA) is accepted as the most accurate source of information for nonlinear seismic response, nonlinear static procedures (NSP) may also provide reasonable estimates of seismic demand and inelastic behavior. However, all proposed NSPs have limitations, due to the certain approximations and simplifications, such as invariable load pattern a...
Experimental investigation of uplift on seismic base isolators / Erkakan, Evren; Caner, Alp; Department of Civil Engineering (2014) Elastomeric rubber bearings reinforced with steel shims, are used to provide structural support in vertical direction and allow horizontal movements for the structure subjected to earthquake and thermal loads. Generally, it is known that tensile stress or uplift may occur when the structure is subjected to strong ground motion or structure have large height-to-width aspect ratio to develop a stability concern subjected to lateral loads. The main focus of this research is to investigate the change in charact...
