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 using the results of benchmark nonlinear response history analysis, and both the conventional and the multi-mode pushover analyses. In comparative evaluations, a twelve-story RC plane frame and a six-story unsymmetrical-plan RC frame are employed by using 91 ground motion components. It is observed that the proposed procedure estimates the flexural deformation demands in deformation-controlled members and the shear forces in force-controlled members with reasonable accuracy.

Evaluation of displacement coefficient method for seismically retrofitted buildings with various ductility capacities Dicleli, Murat (Wiley, 2014-07-25) This research study is aimed at evaluating the accuracy of the displacement coefficient method (DCM) of FEMA 440 and associated nonlinear static procedure (NLSP) for actual buildings with soft story mechanism and various ductility capacities. The DCM and associated NLSP are evaluated using two existing seismically vulnerable buildings with soft story mechanism. The buildings are first retrofitted using a ductile steel-brace-link system to represent those with good ductility capacity and then retrofitted wit...
Comparison of 2D versus 3D modeling approaches for the analysis of the concrete faced rock-fill Cokal Dam Arıcı, Yalın (Wiley, 2013-12-01) This paper's primary purpose is to compare the 2D and 3D analysis methodologies in investigating the performance of a concrete faced rock-fill dams under dynamic loading conditions. The state of stress on the face plate was obtained in both cases using a total strain based crack model to predict the spreading of cracks on the plate and the corresponding crack widths. Results of the 2D and 3D analyses agree well. Although significantly more demanding, 3D analyses have the advantage of predicting the followin...
PREDICTION OF SEISMIC ENERGY-DISSIPATION IN SDOF SYSTEMS NURTUG, A; Sucuoğlu, Haluk (Wiley, 1995-09-01) A simple analytical procedure is developed for calculating the seismic energy dissipated by a linear SDOF system under an earthquake ground excitation. The ground excitation is specified by its pseudo-velocity spectra and effective duration whereas the SDOF system is defined by its natural period of vibration and viscous damping ratio. However, the derived relationship for the energy dissipation demand under an earthquake excitation is sensitive neither to the viscous damping ratio nor the ductility ratio w...
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...
Prediction of input energy spectrum: attenuation models and velocity spectrum scaling Alici, F. S.; Sucuoğlu, Haluk (Wiley, 2016-10-25) Recent improvements in performance-based earthquake engineering require realistic description of seismic demands and accurate estimation of supplied capacities in terms of both forces and deformations. Energy based approaches have a significant advantage in performance assessment because excitation and response durations, accordingly energy absorption and dissipation characteristics, are directly considered whereas force and displacement-based procedures are based only on the maximum response parameters.
