The improvement of structural capacity against large displacement demand of near-fault ground motions has been the subject of research for the last decade. Parallel to the developments in performance-based seismic design (PBSD) this issue has attracted researcher interest further, as assessment of structural displacement capacity has become one of the main concerns for the procedures employed in this new design concept. This Chapter focuses on the near-fault ground motion demand and corresponding structural capacity requirements. We have used soil site, near-fault records from various M > 6.5 events including the 1999 Turkey and Taiwan earthquakes. The spectral quantities were computed through an attenuation relationship that is based on these near-fault ground motion records. We employ these spectral quantities to calculate the distance and magnitude dependent inter-story drift demand limits for frame-type structures. We compare our findings with the Uniform Building Code provisions and other attenuation relationships used in defining the NEHRP spectrum shapes.

Raised drift demands for framed buildings during near-field earthquakes Gulkan, P; Yazgan, U (2004-05-21) The improvement of understanding structural capacity against large displacement demand of near-fault conditions has become a subject of research interest for the last decade. Parallel to the developments in performance-based seismic design (PBSD) this issue has attracted researcher interest further, as assessment of structural displacement capacity has become one of the main issues for the procedures employed in this new concept. This study focuses on the near-fault ground motion demand on framed structures...
Peak ground velocity sensitive deformation demands and a rapid damage assessment approach Akkar, S; Sucuoğlu, Haluk (2003-05-13) The effect of peak ground velocity (PGV) on the maximum inelastic deformation demand of simple, non-degrading structural systems is studied. Ground motion data sets are assembled for pre-defined ranges of PGV and they are used to conduct nonlinear response history analysis of single-degree-of-freedom (SDOF) systems. The study is focused on short and intermediate periods of vibration (T) and strength reduction factor (R) is used to define the lateral capacity of the structure. As part of the study, a simple ...
Kinetic facades for maximizing human comfort and increasing space use efficiency in highly glazed building interiors Ulular, Ilgın Büke; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2022-12-02) Environmental problems are one of the major concerns for the present time, and the building construction sector has a significant impact on the environment. So, existing buildings should be evaluated for efficient use. In public buildings where people can choose seats, efficient space use can decrease because of discomfort. Facades are significant to provide these conditions. Kinetic facades can be considered as an efficient option with their technological systems. In the literature, few studies are related...
Overlapping Lattice Simulation of Concrete Gravity Dam Collapse Simulations SOYSAL, BERAT FEYZA; Aydın, Beyazıt Bestami; Tuncay, Kağan; Arıcı, Yalın; Binici, Barış (2017-09-01) Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. The purpose of the study is to investigate the seismic expected damage levels by using the overlapping lattice modeling (OLM) approach with incremental dynamic analysis (IDA) for two representative dam monoliths. OLM employs pin connected bar elements exten...
Torsional hysteretic damper for seismic protection of structures Salem Milani, Ali; Dicleli, Murat; Department of Engineering Sciences (2014) During the past decades, use of supplementary systems for seismic control of structures has gained increasing acceptance, and research has flourished on development and performance characterization of such systems. These include isolation systems and energy dissipation devices (dampers). This study is devoted to development of a new hysteretic damper for seismic protection of structures. The new system is a stand-alone damper, named Multi-directional Torsional Hysteretic Damper (MTHD). MTHD is composed of e...
