1、3. 1. 1恒载恒载:又称永久荷载,在结构使用期间内,荷载的大小不随时间的推移而变化、或其变 化与其平均值相比较可以忽略不计、或其变化是单调的并能趋于限值的荷载。如结构自重、 构造层重、土压力等。结构白重和构造层重的标准值计算,可按照施工图纸的设计尺寸和材料的单位体积、或 面积、或长度的重力,经计算直接确定:土压力标准值的计算详有关基础设计资料。楼面恒荷载楼面恒荷载主要由三部分组成:建 筑面层恒荷载、结构层恒荷载、顶棚恒 荷载,分布形式详图3. 1.1所示。(1)由建筑面层引起的楼面恒荷载 计算建筑面层引起的楼面恒荷载计算, 必须根据建筑楼面面层的具体做法 确定,常用建筑楼而面层恒荷载取值可
