Time integration is the most versatile tool for analyzing semi-discretized equations of motion. Nevertheless, the associated computational costs are generally high and th [...]

Due to various deficiencies and inadequate lateral stiffness many reinforced concrete buildings are highly damaged or collapsed in Iran and throughout the world during th [...]

In recent years, in conjunction with developments of supplemental passive energy absorption devices , the idea of buckling of thin-walled tube and the use of this propert [...]

It is obvious from experience that structures which had not been designed and constructed according to standard codes, and therefore do not have enough lateral stiffness, [...]

Lack of integrity and ductility are two main reasons for seismic vulnerability of un-reinforced masonry (URM) walls and buildings. Constructing the walls without head joi [...]

Use of side plate in moment connections has enhanced the seismic behavior of connection specially in retrofitting project. The geometry of this connection eliminates reco [...]

In the last three decades, many researches have been carried out on steel plate shear walls, SPSWs, and they have been introduced as seismic load resisting systems. Howev [...]

There exist many cities in developing countries which are built with minimal seismic considerations. Also, due to the expenses regarding in detailed and analytical identi [...]

In this paper, a new pattern for lateral load used in equivalent static method for seismic designing the structures, is proposed and effect of this pattern on distributio [...]
