摘要
深入研究新型混凝土无梁空心板基本力学性能有助于该技术的工程推广和应用。通过ANSYS有限元分析方法对新型混凝土无梁空心板的应变、应力分布规律进行了深入研究,验证了该空心板的双向承载性和"平截面假定"。并以此为基础结合钢筋混凝土受弯构件正截面承载力计算方法介绍了适用于该新型混凝土无梁空心板的正截面承载力简化设计计算方法。
The study on the basic mechanical properties of new concrete girderless hollow slab is beneficial to its promotion and application.Based on the ANSYS finite element analysis method,the strain and stress of this new concrete girderless hollow slab are calculated.It is found that the biaxial bearing capacity of this hollow slab is high,and the strain accords with plane cross-section assumption.Finally,a simplified calculation method of normal section bearing capacity is put forward.
