摘　　要：利用ANSYS对12层不同模型钢板深梁填充钢框架结构(SDBF)进行了时程分析,主要探索钢板深梁刚度变化对结构的影响。分析表明:在水平地震作用下,钢板深梁刚度变化虽然并未改变薄弱层的位置,但是对结构薄弱层的抗侧移能力有显著的影响;随着结构刚度的增大,柱底剪力占基底总剪力的比例不断减小,钢板深梁剪力占基底总剪力比例不断增大,因此通过变化刚度来调节钢板剪力是有效的。经济合理的SDBF结构具有一定的工程应用价值。Time history analysis was made for a 12-story different steel deep beams infilling frame （SDBF） by using the finite element analysis software ANSYS to explore the influence of stiffness change of steel deep beams on structure.Results show that：different steel deep beams do not change the position of the weak storey but have a remarkable effect on lateral force resisting ability of the weak storey under horizontal earthquake action; the column base shear ratio decreases while steel deep beam base shear ratio increases with the increase of the rigidity of the structure.It is effective to regulate steel deep beam base shear by changing the rigidity.Economic and reasonable SDBF structure is of certain value to engineering application.
