中日欧美4个国家和地区的规范和设计建议中对地震作用下侧移的验算规定进行总结,经比较发现,各国的规定有4个不同层次的侧移验算,分别是:重现期为8～95年的使用极限状态验算、地震作用标准值、设防烈度地震和罕遇地震下的侧移验算四种,各国之间差别非常大,限制侧移出发点有:不影响设备的使用、限制围护材料的破坏、限制混凝土构件开裂和设防烈度地震或罕遇地震下不倒等等,其中,中国的最为严格,罕遇地震下侧移验算只有中国才要求。
In the norms and design proposals of 4 countries and regions in Japan, Europe and the United States, the checking provisions of lateral displacement under earthquake action are summarized. The comparison shows that there are 4 different levels of side-shift checking in different countries, namely: 8 to 95 years of the use of the limit state checking, the standard value of the earthquake, fortified seismic earthquake and rare earthquake under the side-shift calculation of four, the difference between countries is very large, limit the starting point of the shift are: does not affect the use of equipment, restrictions The destruction of the envelope materials, the cracking and fortification of concrete components are limited. Earthquakes or rare earthquakes do not fall. Among them, the most stringent in China, lateral displacement checking under rare earthquakes is only required by China.
