摘要
采用重力加载系统 ,模拟预应力混凝土板梁在正常使用极限状态的荷载效应 ,对试验板梁的应力、应变、挠度和裂缝进行理论计算 ,通过理论值与实测结果的对比分析 。
With gravity loading system to simulate the load effect of prestressed concrete(P.C) slab beam at normal working limit state, it is aimed to calculate theoretically the stress, the strain, the deflection and the width of cracks of the slab. This article compares the theoretical value with trial results, to evaluate the bearing capacitym of the trial slabs.\;
