Background and purpose: Physical activity is one of the components of impulsivity and is one of the risk factors for falls in elderly. In the other words, it causes loss of balance. The aim of this study was to investigate the relationship between impulsivity level in elderly and their ability in maintaining balance. Materials and methods: This cross-Sectional study was performed in 50 elder...

This paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of Iranian Standard 2800. Seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. These models cover a wide range of very torsional...

A proper composition of stiffness and ductility parameters is required to obtain a resistant and economic structure. Accordingly, Chevron Knee Braced Frame (CKBF) seems appropriate due to its proper seismic performance. The advantage of this system comes to having the capability of rapid and cheap replacement of chevron knee elements after an earthquake occurs. In this research, response modifi...
