Time integration is a powerful tool in time history analysis against seismic excitations. Nevertheless, the computational costs are considerable and inaccuracies exist fo [...]

The present study investigates the collapse potential of vertical irregular moment-frame system based on the performance based plastic design methodology (PBPD). The well [...]

Dampers are used in structures to dissipate input energy caused by severe earthquakes. They can also reduce seismic demands on other structural elements. So dampers’ li [...]

It is common in structural design to use separate load resisting system in each principal direction of the buildings. In these systems, columns which are located in the i [...]

In this paper, developing process of the Iranian national rural building code (The national code for low-rise residential buildings) is reviewed. While earthquakes are re [...]

The construction of a wide range of typical Iranian steel buildings a large number of which were built before 1990 was based on no seismic code. According to the experien [...]

Bracing members in concentrically braced frames are specially designed to undergo plastic deformations and dissipate hysteretic energy through successive cycles of inelas [...]

In recent decades, shear walls and tube structures are the most appropriate structural forms, which have caused the height of concrete buildings to be soared. So, recent [...]
