Isolation of buildings from earth vibrations is a new method that has been considered in the last few decades and is the only way to reduce simultaneously the inter-story displacement and acceleration of stories. In this method, increasing the period

One of the methods of resisting to earthquake forces and its undesirable effects on structures is the use of seismic isolators. Investigations on the seismic structure have been initiated by researchers since decades, but so far no study has been don

Steel connections are used to connect between beam and column in steel moment frame structures. As of present time, there is a huge lack of understanding of the performance of steel connections and their response to fire especially the uncontrolled f

Progressive collapse is defined as the expansion of an initial local failure of an element into another element of the structure and ultimately leading to the collapse of the whole structure or a large part of it in a disproportionate way. Three dime

The resistance of beam-to-column connections to fire is an important consideration for the design of steel moment frames. The authors seek to study the effect of fire on such connections using finite element modeling in ABAQUS. The previously publish
