［摘要］针对一栋高宽比为8的高层商住楼项目的建筑结构设计，对剪力墙结构有害位移角的不同算法进行了比较，并介绍了其中一种算法对该项目结构有害位移角的分析结果，提出了一种相对合理的有害位移角计算方法，供类似大高宽比高层结构设计参考。最后提出了对有害位移角及总位移角分别设定位移限值的观点。

Abstract:Based on the structural design of a high-rise building whose height-width ratio is 8，the different calculation methods of the harmful displacement were compared，and one of the results of the structural displacement was introduced. A reasonable calculation method of the harmful displacement was proposed.Results can be used as references for similar engineerings. The viewpoint that harmful displacement and total displacement should have different limited values was put forward.

Keywords:high height-width ratio; high-rise building; harmful displacement; harmless displacement; limited value of displacement
