摘要

摘要: 加劲肋空心管现浇钢筋混凝土无梁楼盖是一种新型的空心无梁楼盖体系。为了了解这种楼盖体系的受力性能，开展四边简支楼盖模型试验。试验表明，这种楼盖体系具有承载力高、刚度大、延性好的受力性能。根据试验现象，提出将加劲肋空心管无梁楼盖比拟成正交异性薄板的理论分析方法，根据理论计算结果与试验实测结果的对比，表明该方法是正确合理的，计算结果与试验结果吻合良好。

Abstract: Stiffening ribbed hollow pipe cast-in-place reinforced concrete girderless floor is a new style hollow girderless floor system. Model experimental research on simply-supported floor has been done on this new kind of floor system. The experiment results show that the floor system has the mechanical property of high bearing capacity,big rigidity and good tensility. A theoretical method is presented that the stiffening ribbed hollow pipe girderless floor can be analyzed by converting it equivalently to orthotropic solid slab. It is indicated that the method is correct and reasonable according to the contrast of theoretical calculated results and experimental measured results. The theoretical results coincide with the measured results well.
