1、明A.1压型钢板钢筋桁架组合楼承板的性能特点压型钢板钢筋桁架组合楼承板在施工阶段自身承受楼板湿混凝土自重及相应的施工荷载，不需要设置支撑;在使用阶段钢筋桁架上下弦钢筋与混凝土整体共同工作承受使用荷载。A.2压型钢板钢筋桁架组合楼承板的设计与选用说明压型钢板钢筋桁架组合楼承板应按单向板进行设计，跨中板底钢筋、支座负筋均应按计算确定，顶部横向分布筋须满足构造要求。当无特殊防火措施情况下，底板一般不参与使用阶段结构计算，仅作模板用C对一般工业与民用建筑，确定结构平面布置后，按附录B的允许跨度选用合适的板型，并复核板跨中底部钢筋是否满足使用阶段计算要求；支座负筋及顶部横向分布钢筋须按照计算结果另行图纸
