The Effect of Seismic Design on Structural Progressive Collapse

Earthquake action is an important factor that affects structural progressive collapse,first.the characteristics of the earthquake action are analyzed,the seismic design and collapse-resistance design are compared,in order to consider the effect of seismic intensity on the structure,non-seismic and seismic intensity of 6(0.05 g),7(0.1 g),8(0.2 g) of four typical four-layer frameworks were established.According to GSA guidelines,using the linear static analysis the frameworks' collapse-resistance capacity were analyzed.The results show the collapse capacity of 6 and 7 degree improved less than non-seismic structure;the collapse capacity of 8 degree is better.
