预制带肋底板混凝土双向叠合板极限承载力
|
摘要
为适应复杂荷载条件及不同的楼盖跨度,对预制带肋底板的结构体系进行了拓展。基于塑性绞线理论,推导了均布荷载作用下常见边界条件预制带肋底板混凝土双向叠合板(双向叠合板)的极限承载力与塑性绞线形成位置,提出了双向叠合板正交2个方向单位宽度极限弯矩的简化计算公式,进行了均布荷载作用下四边简支与四边固支双向叠合板2个算例的塑性极限分析,结果表明:基于该文给出的极限承载力公式的计算结果与试验结果吻合较好。
New types of precast concrete ribbed panels are developed in order to adapt to the complex loading conditions and different floor spans.Based on the yield line theory,equations for the ultimate bearing capacity and yield patterns of two-way composite slabs of different edge conditions and under uniformly distributed loading are developed,and the simplified formulas for the ultimate moment per unit width are proposed.The plastic limit analyses of two examples on the simple support and the fixed support are conducted,and the calculation results show good agreement with the experimental data.
