response modification factor (r factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. this paper has tried to evaluate the response modification factor of concrete coupled shear wall structures with various length/depth ratios of spandrel beams. the effect of diagonal reinforcement of spandrel beam was also evaluated o...

time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. one of the important issues in the time-history analysis is selecting earthquake records. in this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. a...

Women’s rights are closely related to economic development. This is true both across countries, where women have most rights in the richest countries, and in time series data: women have slowly improved their legal position in parallel with fast improvements in the standard of living. In most cases, the initial extension of rights to women amounted to a voluntary renouncement of power by men. I...
