在住宅、宿舍、办公楼等多层砖房的抗震设计中,一般以现有震害为经验,以抗震设计规范为标准,主要是对房屋的薄弱环节加强构造措施,而不进行强度验算。其因是,目前对多层砖房的强度验算方法与实际震害相差太大,尤其是顶层,相差可达2～4倍;其次计算方法是按单片墙进行,步骤太繁,使设计人员难以采用。由于上述原因,强度验算失去指导意义,这样在抗震设计中,尤其在抗震加固设计中,存在较大的盲目性,设计标准极不统 In the seismic design of multi-storey brick houses such as houses, dormitories, and office buildings, the existing seismic damage experience is generally used, and the seismic design code is used as the standard. This is mainly to strengthen the structural measures for the weak links of the house without performing strength verification. The reason is that the current method for checking the strength of multi-storey brick houses is very different from the actual damage, especially the top layer, which can be up to 2 to 4 times different; the second method is based on a single wall, and the steps are too numerous to make the design. It is difficult for people to use. Because of the above reasons, the intensity check loses its guiding significance. In this way, in the anti-seismic design, especially in the anti-seismic reinforcement design, there is a large blindness, and the design standard is extremely unsystematic.
