摘　　要：通过对钢筋混凝土双向密肋楼盖在均布荷载作用下的试验,测出楼盖的实际承载能力、楼盖双向中线的各点挠度及楼盖在各级荷载作用下的最大裂缝宽度,并描出板底裂缝分布图形.钢筋混凝土双向密肋楼盖的破坏特点和受力性能进一步得到证实.实验结果表明,钢筋混凝土双向密肋楼盖在均布荷载作用下,其极限平衡荷载理论计算值与实际试验结果十分相近.楼盖中心最大挠度理论计算值也满足正常使用极限状态的要求.The maximum load of two-way reinforced solid slabs and their bending near the two-way central line were measured experimentally. Moreover, we got the maximum width of cracks under various loading levels, and obtained the graphs of cracks position. Finally, we gave out the damage characteristics and the load performance of two-way (reinforced) solid slabs. The result of experiments showed that the two-way (reinforced) solid slabs under various loads. The numerical results is very close to the experimental values.
