چکیده مقاله
The progressive collapse resisting capacity of the three story steel moment frames designed for moderate and very high level of seismic zones of Iran, is investigated using alternate path method recommended in the GSA and UFC guidelines The linear static and nonlinear static analysis procedures were carried out in accordance with both the guidelines It was observed that, for the steel structures designed for higher seismicity there is higher capacity for progressive collapse However for short steel structures, there is no enough redundancy, hence the alternate paths will not be generated to redistribute loads of the failed elements and prepare resisting capacity for progressive collapse It was also observed that, the direction of joist and pattern of gravity loads are effective parameters and so, it is better to be avoided from uniform gravity loading patterns
