| 摘 要： | 为了研究现浇钢筋混凝土双向板肋梁楼盖中梁与板的相互作用,对一柱支承的现浇钢筋混凝土角区格双向板肋梁楼盖进行了均布荷载作用下的逐级加荷试验,分析了其裂缝出现和开展过程、破坏形态以及受力性能.基于试验结果,提出了这种楼盖结构的破坏机构,并推导了相应的极限荷载计算公式.将试验所得的板内力分别与弹性理论、塑性理论计算结果进行比较,表明按弹性理论以及基于板破坏模式的塑性理论所得结果与试验结果差别较大.

| Abstract: | In order to research the interaction of beam and slab,a cast-in-situ reinforced concrete corner lattice two-way slab supported by columns has been tested step by step under uniform load,and beam's and slab's crack developing process.The failure pattern and mechanical behavior have been analysed.Based on the test results,failure model was set up,and its ultimate loading formula was derived.Comparrison of the test results and the results calculated in elasticity and plasticity theory is made,which shows that ... |
