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…
An investigation on the effect of the near-fault earthquakes on the seismic behavior of RC Moment Resisting Frames (MRFs) designed based on Iranian seismic code (standard no. 2800)
Mojtaba Harati, Ahmad Hojjati, Ataalh Modaraei
Past severe earthquakes, such as Bam earthquake of 2003 and Tabas earthquake of 1978, have demonstrated that many cities in Iran are prone to be struck by near-fault earthquakes. S…
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…
