底部框架-抗震墙房屋由于上下部结构特性差异较大,故抗震性能较差,但鉴于我国目前的基本国情,这种结构的房屋还将存在相当的时间。对于此类结构的房屋,只要在设计中严格执行抗震规范,进行合理的结构布置并对其重点部位采取有效的抗震措施进行处理,把握好其设计要点,就能达到房屋抗震的“三个水准”的设防目标。
The bottom frame-earthquake-resistant wall houses have relatively poor seismic performance due to the large differences in the structural features of the upper and lower parts. However, due to the current basic national conditions in China, there will be considerable time for such structures. For such structures of houses, as long as the strict implementation of the seismic design in the design, the rational layout of the structure and effective measures to deal with the seismic focus of its site, grasp the design points, will be able to achieve earthquake-resistant housing, “three Level ”fortification target.
