［摘要］建筑設計中特別是超高層建筑設計中，經(jīng)常會遇到電梯地坑不落地而是吊掛在某層樓板之下，需要依據(jù)新版《建筑結構荷載規(guī)范》(GB 50009—2012)要求進行防止電梯偶然墜落荷載作用下的強度驗算。結合工程實例對其進行歸納總結分析。

Abstract: The elevator supporting bottom slabs do not fall to the ground and often hung under a certain floor in the architectural design, especially for super high-rise buildings. In these circumstances, under the new version Load code for the design of building structures (GB 50009—2012), bearing strength calculation of the elevator suspended bottom slab resisting the accidental load is demanding. Combining practical engineering experience, outlines of calculation and design of the elevator suspended bottom slabs resisting the accidental load are analyzed and summarized.
Keywords: suspended bottom slab; accidental load; impact load; calculation and design
