摘　　要：在目前使用比较普遍的多高层空间有限元结构分析软件PKPM-SATWE中,连梁的建模方法可以采用按框架梁输入和按剪力墙开洞方式输入,在两种输入方式情况下,连梁内力计算结果有所不同。经过计算分析对比可知,按剪力墙开洞模拟连梁,其受力结果更接近工程实际受力状态;在剪力墙开洞输入方式下,不同墙元细分最大控制长度对计算结果的影响不可忽略;墙元细分控制长度取值越小,计算越精确,但计算所需时间也会越长。In the current use of the more common multi-high-level space finite element analysis software PKPM-SATWE,the modeling method of coupling beams can be used according to the frame beam and shear wall with opening input method. Beam internal force calculation results vary in two input modes. According to the simulation of the shear wall with opening,the stress results closer to actual stress state after calculation and analysis. According to the shear wall with opening input method,the influence of the maximum control length of different wall elements on the calculation results can not be ignored. The smaller themaximum control length of the wall element subdivision, the more accurate calculation,but the calculation time will be longer.
