消防车等效荷载表

编制日期:2007.06.25

(单向板按<荷载规范>GB50009-2001之附录B计算,适用于消防车满载总重为300kN的大型车辆.按车辆最大轮压为60kN,作用在0.6mx0.2m的局部面积上的条件并按最不利组合确定。双向板按弹性薄板小挠度理论计算确定。)

本表的适用范围：1. 设计楼板可以直接采用本表数据。2. 设计楼面梁：1）对单向板楼盖的次梁和槽形板的纵肋可乘以0.8的折减系数。2) 对单向板楼盖的主梁可乘以0.6的折减系数。3)对双向板楼盖的梁可乘以0.8的减系数。3. 设计墙、柱和基础时：1）对单向板楼盖可乘以0.5的折减系数。2) 对双向板楼盖和无梁楼盖可乘以0.8的折减系数。
