In fact , the collapse of structure is process in which damage of structure is deposited and developed constantly . in this thesis the evolvement process of damage of rc frame structure is studied and simulated by method of numerical on base of damage 实际上，结构在地震力下的破坏过程是一个损伤不断累积并发展的过程，本文从损伤的研究观点出发，对地震力下框架结构的损伤演化过程进行了研究并借助于计算机对结构在地震力作用下的损伤演化情况进行数值模拟。
So , we can draw some conclusions as follows : the method of upgrading the seismic - measures which is adopted by gb50223 - 95 is effective and is more effective than the method of upgrading the earthquake - design - level for those category frames of which seismic - measures are needed to be upgraded from grade 2 to grade 1 . but for those category frames of which seismic - measures are not upgraded from grade 2 to grade 1 ( e . g . those frame of which seismic - measures are needed to be upgraded from grade 3 to grade 2 or from grade 4 to grade 3 ) , whether the method of upgrading seismic - measure is more effective than the method of upgrading earthquake - design - level needs further research 因而可以有如下结论， gb50223 - 95对乙类建筑所采用的提高抗震措施等级的设计思路是有效的，并且，对于抗震措施需从二级提高到一级的乙类建筑，该方法比提高设计地震力的方法更为有效；但对于抗震措施不是从二级提高到一级（如从三级提高到二级、或从四级提高到三级）的乙类建筑，提高抗震措施等级的方法是否一定比提高设计地震力的方法更有效尚需作进一步探讨。
The paper also compared fsmrcwb with frame - supported masonry wall beam ( fsmwb ) . secondly , by means of finite element method ( fem ) , the paper studied stress distribution in fsmrcwb under vertical loads and under elastic earthquake force with constant vertical loads respectively 其次，进行了框支密肋复合墙梁的线弹性有限元分析，主要研究框支密肋复合墙梁在竖向荷载作用下的应力分布，以及在竖向荷载与小震水平地震力共同作用下的应力分布，并就试验结果与有限元分析结果进行对比分析。
Structural internal forces and deformation caused by seismic load are bigger than that caused by automotive load . seismic load controls the designing of large span and small " width - to - span " ratio of large span cfst arch bridge . the seismic resistance is bigger than that with considering combination of various directions , so seismic load combination of various directions should been taken into account during design of large span cfst arch bridge 地震荷载所引起的内力和变形均大于车辆荷载引起的内力变形，对大跨、宽跨比小的钢管混凝土拱桥来说，应以地震荷载控制内力和变形设计，考虑多方向地震荷载的组合后，所得的地震力更大，说明在计算地震力时，应该考虑多方向地震荷载的组合。
