提出考虑人防要求的地下室顶板结构二步设计法,解决了由于《六级人民防空地下室设计规程》(后简称《规程》)要求考虑核爆动荷载与其它荷载组合后的特大荷载作用下的大柱网地下室的设计难题,以及《规程》与现行的有关设计规范设计基准不一致给设计带来的困难。 A two-step design method for the roof structure of a basement considering the requirements of air defense was proposed to solve the problem of large loads due to the combination of nuclear explosion dynamic load and other loads as required by the “Six Civil Air Defense Basement Design Rules” (hereinafter referred to as “the Regulations”). The design difficulties of the column basement, and the inconsistency between the “Regulations” and the current design specifications of the relevant design specifications give rise to difficulties in design.
