建筑楼面多种活荷载组合系数设计方法探讨

图书馆、档案馆等建筑内除了设置有藏书库外,一般还有阅览室、会议室及各类办公用房等,而各类教学楼、办公楼等建筑可能也会划定部分楼面作为藏书库。藏书库的楼面荷载取值比一般的楼面荷载都要大,根据《建筑荷载规范(GB5009-2001)》和《建筑抗震设计规范(GB50011-2001)》的要求,藏书库与其它功能的楼面在计算荷载组合和重力荷载代表值时所采用的可变荷载组合系数是不同的。为此对两部规范中提到的可变荷载组合值系数进行辨析,然后探讨在结构设计中运用常用的结构设计软件满足两部规范对可变荷载组合值系数取值的复杂要求。

Design Method for Buildings with Multiple Live Load Coefficients for Combination Values

Library buildings and archives buildings include not only large area of stack rooms,but also sizable area for reading rooms,meeting rooms or offices;on the contrary,part of the floor area of school buildings or complex office buildings may also be used as stack rooms.The uniform live load for stack rooms is significantly larger than the typical floor types.Moreover,both Load Code and Seismic Code respectively define Live load coefficient for combination values,which are not identical in meanings and values ...
