摘要
当多层工业厂房采用等效均布楼面活荷载计算重力荷载代表值时,GB50011-2001(2008年版)《建筑抗震设计规范》均未明确规定对应的可变荷载地震组合值系数ψEC的取值。文中通过2个典型工程算例的比较,发现ψEC对多层工业厂房地震作用计算结果影响较明显,并探讨ψEC的取值原则和提出若干建议,可供多层工业厂房抗震设计参考。
The Code for Seismic Design of Buildings（GB50011-2001,2008 version）has not specified live load seismic combination coefficient ψEC for multi-storey factory building. The paper presents two typical calculation examples to demonstrate the importance of ψEC for seismic design of multi-storey factory building,discusses rational range of ψEC. Recommendations on values of ψEC under different circum- stances are also provided,which can be reference for seismic design of multi-storey factory building.
