［摘要］防空地下室在战时具有预定的武器防护能力，其结构设计具有构件可靠度低、有动力响应、材料强度高、允许进入塑性状态、可不验算变形裂缝和各部位等效静荷载不同的特点。本文以甲类核6级防空地下室为例介绍了等效静荷载的选取及影响因素，说明了结构构造的重要性，对比了防空地下室设计与抗震设计的联系与区别。

Abstract： Civil air defense basement has a predetermined protection ability of weapons in wartime， which owns such characteristics including low reliability, dynamic response， increasing the strength of the material， allowing to work in a plastic state， no checking deformation and crack， and the value of the equivalent static loads at different locations are different． The equivalent static load of nuclear grade 6 air defense basement and influencing factors were introduced and the importance of detailing requirements were emphasized． The relation and the difference between seismic design of buildings and design of air defense basement were compared．

Keywords： civil air defense basement； structural design characteristic； equivalent static load
