Nonlinear behavior of RC shear walls: From experiments to the field reports
Mojtaba Harati, Mohammadreza Mashayekhi, Ali Khansefid +2
Post-earthquake damage evaluation has indicated that although the buildings with shear walls exhibited an appropriate overall performance in the recent severe earthquakes, in some…
Incorporation of Strong Motion Duration in Incremental-based Seismic Assessments
Mohammadreza Mashayekhi, Mojtaba Harati, Atefeh Darzi +1
This study proposes a new approach to incorporate motion duration in incremental dynamic assessments. In the proposed methodology, at each intensity level, a simulation-based appro…
A state-of-knowledge review on the Endurance Time Method
Homayoon E. Estekanchi, Mohammadreza Mashayekhi, Hassan Vafai +3
Endurance time method is a time history dynamic analysis in which structures are subjected to predesigned intensifying excitations. This method provides a tool for response predict…
Introducing a response-based duration metric and its correlation with structural damages
Mohammadreza Mashayekhi, Mojtaba Harati, Morteza Ashoori Barmchi +1
This study proposes a response-based parameter for strong motion duration which is computed for structures and is the total time they are nonlinear during an earthquake. Correlatio…
On the optimal parameters of a PSO-based algorithm for simulation of Endurance Time Excitation Functions
Mohammadreza Mashayekhi, Mojtaba Harati, Homayoon E. Estekanchi
This paper presents a particle swarm optimizer for production of endurance time excitation functions. These excitations are intensifying acceleration time histories that are used a…
Influence of ground motion duration on the structural response at multiple seismic intensity levels
Mojtaba Harati, Mohammadreza Mashayekhi, Morteza Ashoori Barmchi +1
This paper aims to investigate the effects of motion duration on the structural seismic demands, seeking potential correlations between motion durations and structural responses at…
