| 1. | This kind of structure is bad for anti - earthquake due to the bigger departure of its center of mass and center of rigidity . the structure is irregular both in plane and vertical , and the power character of this structure in the both principal axes is different a lot , so , that ’ s seismic unfavorable
这种结构体系由于其质心和刚心偏离较大,结构在平面及竖向均不规则,结构的两个主轴方向动力特性相差较大,对抗震来讲是非常不利的。 |
