摘要
为研究负弯矩钢筋保护层厚度在大于设计要求1倍情况下,对楼面板承载力及挠度的影响。文中以某工程为例,采用弹性薄板理论、ANSYS有限元分析法和静载试验法研究双向板的承载力和挠度。结果表明楼面板承载力及挠度满足规范要求,为类似工程提供参考。
To study the influence of the thickness of the reinforcement cover of the negative bending moment rein-forcement on the bearing capacity and deflection of the floor panel when it is thicker than 1 times the design require-ments.Taking an engineering floor panel as the case,ANSYS finite element analysis with elastic sheet theories,and the static load test method were used to study the bearing capacity and deflection of the two-way slab.The results show that the bearing capacity and deflection of the floor slab meet the requirements of the codes,which provides reference for similar projects.
