对于以剪切变形为主的结构，计算模型采用层间剪切模型，及房屋的质量集中于各楼层，在振动过程中各楼层始终保持为水平，结构的变形为层间错动，各层的层间位移具有独立性，互不影响。-For shear deformation in the structure calculation model using interlaminar shear model, and focus on the quality of housing on each floor, each floor during vibration level is maintained, the deformable structure as an interlayer dislocation layers inter story drift independence of each other.
