The number and severity of natural disasters have increased continuously over recent decades, especially in developing countries. The World Bank has estimated that 97 per [...]

Damages created in several relatively new buildings in recent earthquakes have shown that some of seismic design codes, which are strength-based, do not necessarily resul [...]

Seismic risk reduction for the intercity road systems, as the necessary tools for emergency response activities and reconstruction purposes in the aftermath of major eart [...]

When the excitation frequency at the base of a building is close to one of its modal frequencies other than its first mode, the contribution of that mode in comparison wi [...]

It has been claimed by many researchers that the direction of dominant excitation might be none of the main directions of the building axes. However, the researches perfo [...]

In this paper, the issues of temporary shelters and reconstruction are considered from three points of view: 1) Government involvement, 2) Community contribution, and 3) [...]

Seismic design codes give various values for Response Modification Factor (RMF) depending on the lateral load bearing system of the building structure, for example, they [...]
