In recent years, there has been a strong interest on energy-based design and assessment methods for structural systems. The underlying research has been mostly performed using real ground motion records taken from existing earthquakes worldwide. Results may involve bias due to lack of homogeneity of the available ground motion dataset in terms of magnitudes, source to site distances or soil conditions. In this study a large set of ground motion records is simulated within a parametric exercise to investigate the effect of different intensity measures on the energy-based response of simple SDOF structures. To generate simulated records, the stochastic finite-fault methodology which is effective in simulating a wide range of frequencies including those that influence the built environment is used. The simulations are performed on active faults around Duzce city center located on the western segments of North Anatolian Fault zone in Turkey. The simulated records cover a wide range of moment magnitude, source-to-site distances and soil conditions. To assess the response statistics on SDOF models, time history analyses with simulated records are performed. Input energy, damping energy and hysteretic energy are considered as the main output parameters. The results of this study reveal that energy is a more stable parameter than the other response parameters such as displacement and force. However, it is important to dissipate the estimated input energy through damping and inelastic action. Finally, it is believed that conducting parametric seismic analysis based on simulated records yield realistic results since these records provide variability in seismic demand.

An energy-based seismic response evaluation of simple structural systems with simulated ground motions Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (null; 2017-04-18) In recent years, there has been a strong interest on energy-based design and assessment methods for structural systems. The underlying research has been mostly performed using real ground motion records taken from existing earthquakes worldwide. Results may involve bias due to lack of homogeneity of the available ground motion dataset in terms of magnitudes, source to site distances or soil conditions.

Use of simulated ground motions for the evaluation of energy response of simple structural systems Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (Elsevier BV, 2019-08-01) The literature on energy-based seismic design and assessment methodologies of structural systems mostly relies on real ground motion datasets. However, certain bias exists due to lack of homogeneity in available ground motion datasets. In this study, a large set of ground motions is simulated. Next, the effects of various parameters on seismic behavior of SDOF systems in terms of energy are studied using nonlinear time history analyses. The stochastic finite-fault simulations are performed on the western pa...
Probabilistic seismic hazard assessment for east anatolian fault zone using planar source models Menekşe, Akın; Gülerce, Zeynep; Department of Civil Engineering (2015) The objective of this study is to perform probabilistic seismic hazard assessment (PSHA) using planar seismic source characterization models for East Anatolian Fault Zone (EAFZ) and to update the design ground motions to be used in the region. Development of planar seismic source models requires the definition of source geometry in terms of fault length, fault width, fault plane angles and segmentation points for each segment and associating the observed seismicity with defined fault systems. This complicat...
An improvement to linear-elastic procedures for seismic performance assessment Gunay, Mehmet Selim; Sucuoğlu, Haluk (Wiley, 2010-07-10) An improved linear-elastic analysis procedure is developed in this paper as a simple approximate method for displacement-based seismic assessment of the existing buildings. The procedure is mainly based on reducing the stiffness of structural members that are expected to respond in the inelastic range in a single global iteration step. Modal spectral displacement demands are determined from the equal displacement rule. Response predictions obtained from the proposed procedure are evaluated comparatively by ...
