One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude ...

One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the ...

Rotating beams have been considerably appealing to engineers and designers of complex structures i.e. aircraft's propeller and windmill turbines. In this paper, a new flexibility-based method is proposed for the dynamic ...

Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop ...

Hexagrid structural system is an innovated system with structural behavior which is similar to a tubular system. In this paper, a numerical study is conducted to estimate the seismic performance of horizontal hexagrid ...

The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure.  For this purpose, a 20-story building with a square plan of six by six ...

The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than ...

Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and ...
