建筑物中由于各构件可能存在质量分布不均、构件尺寸差异引起的刚度布置不均，结构质量分布的中心位置与结构刚度分布的中心不重合导致建筑物在地震作用下产生明显的附加转动，引起结构边榀柱受剪扭破坏。构件布置过程中多考虑到如何控制此种扭转效应的问题。文中对减震结构振动方程中附加阻尼矩阵的计算说明了增设阻尼器对结构扭转效应控制的影响，对 L型结构算例中以层间位移、位移比作为控制参数，分析阻尼器的布置方式对结构在地震作用下的减震及扭转效应控制效果的影响，得出了阻尼器在楼层高度、平面内的最优位置以及相应布置下的减震效果。

Considering the inconsistency between the center of mass and stiffness in the construc-tion with the shape of L,Torsional response of structures under earthquake will occur obviously.So,how to control this response is a problem frequently occurred in seismic design.The effection of establishing dampers to control the torsional response is presented.Example of engineering calculation shows the de-crease of the torsional deformation of the structure under earthquake action by using dampers in different locations.
