摘　　要：带框支转换层的复杂高层结构设计中,经常遇到由于转换梁上一层的剪力墙内力突变,造成墙肢配筋困难的情况.有观点认为这是由于转换梁采用的计算单元导致的结果失真.笔者结合工程实例,通过选用不同软件的不同计算单元进行对比分析,研究剪力墙内力突变现象产生的原因.计算结果表明,此位置剪力墙内力突变是真实存在的,受所采用的计算单元类型影响有限.转换梁优先采用壳元进行分析,更为合理.It often encounters the internal force mutation of shear wall due to the transfer beam in the design of a complex high-rise structure with a frame support conversion layer which causes the difficulty of the shear wall reinforcement. It is considered that it is the distortion from the result of the conversion beam used in the calculation. The author makes a comparative analysis of the internal force of the shear wall, which is caused by the difference of the different software. The calculation results show that the internal force of the shear wall is real, and the type of calculation unit is limited. The shell element should be used for the analysis of the transfer beam which is more reasonable.
