Generalized force vectors for multi-mode pushover analysis of torsionally coupled systems Kaatsız, Kaan; Sucuoğlu, Haluk (Wiley, 2014-10-25) A generalized multi-mode pushover analysis procedure was developed for estimating the maximum inelastic seismic response of symmetrical plan structures under earthquake ground excitations. Pushover analyses are conducted with story-specific generalized force vectors in this procedure, with contributions from all effective modes. Generalized pushover analysis procedure is extended to three-dimensional torsionally coupled systems in the presented study. Generalized force distributions are expressed as the com...
Generalized force vectors for multi-mode pushover analysis of bridges Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (2017-12-01) Nonlinear static procedures (NSPs) are gaining wider use in performance based earthquake engineering practice due to their simplicity compared to rigorous nonlinear time history analysis (NTHA), and being implemented in the new generation of seismic design codes. In this study, a recently proposed Nonlinear Static Procedure (NSP) for the seismic performance assessment of building structures using the concept of generalized force vectors (GFV), is further validated through application to reinforced concrete ...
Generalized force vectors for multi-mode pushover analysis Sucuoğlu, Haluk (Wiley, 2011-01-01) A generalized pushover analysis (GPA) procedure is developed for estimating the inelastic seismic response of structures under earthquake ground excitations. The procedure comprises applying different generalized force vectors separately to the structure in an incremental form with increasing amplitude until a prescribed seismic demand is attained for each generalized force vector. A generalized force vector is expressed as a combination of modal forces, and simulates the instantaneous force distribution ac...
Generalized Hybrid Surface Integral Equations for Finite Periodic Perfectly Conducting Objects Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2017-01-01) Hybrid formulations that are based on simultaneous applications of diversely weighted electric-field integral equation (EFIE) and magnetic-field integral equation (MFIE) on periodic but finite structures involving perfectly conducting surfaces are presented. Formulations are particularly designed for closed conductors by considering the unit cells of periodic structures as sample problems for optimizing EFIE and MFIE weights in selected regions. Three-region hybrid formulations, which are designed by geneti...
Generalized Pushover Analysis For Torsionally Coupled Systems Kaatsız, Kaan; Alıcı, Fırat Soner; Sucuoğlu, Haluk (2017-01-13) Generalized pushover analysis procedure that was previously formulated on 2D planar frames is extended to 3D systems with torsional coupling in the presented study. The instantaneous force distribution acting on the system when the interstory drift at a story reaches its maximum value during seismic response is defined as the generalized force distribution. This force distribution is then expressed in terms of combinations of modal forces. Modal contributions to the generalized force vectors are calculated ...
