In this study, two new site specific statistical equations are proposed to estimate the inelastic displacement ratio, C-1 of structures subjected to far fault (FF) and near fault (NF) ground motions. The proposed equations consider the effects of fundamental vibration period of the structure, T, lateral strength ratio, R and frequency content of the design earthquake record represented by the A(p)/V-p ratio (or T-0=2/A(p)/V-p), which is a function of the earthquake magnitude, distance to fault, faulting mechanism and site class. It was observed that the C-1 values obtained from the proposed equations are in good agreement with the calculated results. The flare of the plotted C-1 vs. T/T-0 curves enables the proposed equations to cover nearly all the calculated C-1 data range and give satisfactory results. However, the curves obtained using the C-1 equations of several codes and those available in the literature do not cover the whole calculated C-1 data range and generally give unconservative results (smaller C-1 values) especially in the shorter period range. For the longer period range, the predictions of C-1 obtained from the proposed equation and the ones available in the literature are in good agreement with the calculated C-1 data.

A(p)/V-p specific inelastic displacement ratio for the seismic response estimation of SDOF structures subjected to sequential near fault pulse type ground motion records DURUCAN, CENGİZHAN; Durucan, Ayse Rusen (2016-10-01) This research study is focused on an improved statistical equation proposed to estimate the inelastic displacement ratio, C-1, of structures subjected to sequential (pre-shock, main shock, after shock) pulse type near fault (NF) ground motions. Proposed equation considers the effects of fundamental vibration period of the structure, T, lateral strength ratio, R, and frequency content of the design earthquake on the variation of the response. Frequency content of the design earthquake, represented by the A(p...
Proposed minimum restoring force equations for seismic isolated structures Görgülü, Ali Günalp; Dicleli, Murat; Department of Engineering Sciences (2019) In this research study, a new set of restoring force equations are proposed for seismic isolated structures subjected to far fault ground motions (FFGM) and near fault ground motions (NFGM). For this purpose, 110 FFGM and 49 NFGM are selected. Then, nonlinear time history analyses (NLTHA) of SDOF seismic isolated structures are performed using the selected ground motions to obtain their residual and maximum displacements. The analyses are repeated for an extensive range of parameters including peak ground a...
ACCURATE MATCHING AND RECONSTRUCTION OF LINE FEATURES FROM ULTRA HIGH RESOLUTION STEREO AERIAL IMAGES Ok, Ahmet; Heipke, C.; Rottensteiner, F.; Soergel, U.; Toprak, V. (2011-06-17) In this study, a new reconstruction approach is proposed for the line segments that are nearly-aligned(<= 10 degrees) with the epipolar line. The method manipulates the redundancy inherent in line pair-relations to generate artificial 3D point entities and utilize those entities during the estimation process to improve the height values of the reconstructed line segments. The best point entities for the reconstruction are selected based on a newly proposed weight function. To test the performance of the pro...
Damping reduction equation for the equivalent linear analysis of seismic isolated structures subjected to near fault ground motions Kara, Emra; Dicleli, Murat; Department of Earthquake Studies (2019) In this study, a new damping reduction equation is proposed to obtain reasonable estimates of the actual nonlinear responses of seismic isolated structures (SIS) subjected to near fault ground motions (NGM) with forward-rupture-directivity effect, using equivalent linear analysis (ELA) procedure. For this purpose, first, a set of 29 NGM are selected and grouped according to their site soil classification. Then, the average response spectra of the NGM are plotted and a smoothed design response spectrum for e...
