摘　　要：首先提出了一种新型钢筋混凝土四向肋空心楼板,为研究新型楼板的受力性能,采用ANSYS有限元分析软件建立了四角支承的四向肋空心楼板、两向肋空心楼板及实心板有限元分析模型,分别在三种荷载工况下,分析对比了上述三种混凝土楼板的挠度、应力大小及分布。研究结果表明本文提出的新型钢筋混凝土四向肋空心楼板具有优越的受力性能。In this paper,firstly proposes a new kind of reinforced concrete four-way rib hollow floor,for the study of mechanical properties of the new floor,f our-way rib hollow floor,two-way rib hollow floor and solid floor supported by four corner columns are taken as rational finite element models by ANSYS,comparative analysis of their deflection,maximum stress and distribution patern are presented in detail using three kinds of calculation schemes.Study results show that the new reinforced concrete four-possess rib hollow floor with superior mechanical properties.
