钢筋混凝土空心楼盖在竖向荷载下的简捷计算方法

SIMPLIFIED ANALYSIS FOR HOLLOW-SLAB UNDER VERTICAL LOADS

根据刚度等效的原则 ,将钢筋混凝土空心楼盖等代为正交密肋梁体系 ,板上荷载转化为等效节点荷载后 ,利用现行通用结构分析软件对受各种竖向荷载作用下的钢筋混凝土空心楼盖作精确分析 ,方便地得到楼盖的内力和挠度 .并用实验进行了验证 ,结果表明 。

According to the principle of equivalent rigidity,the hollow-slab was anagogic to closely spaced beams,and the loads upon the hollow-slab can be transformed to equivalent node's load of beams. With this method,the multi-loaded hollow-slab can be analyzed simply and accurately with current software of structure analysis and gain the internal force and deflection expediently.The comparison showed that this method was in good agreement with the test results,hence the method was valuable in practice.
