摘要
通过静力加载试验对比现浇混凝土整体板及在跨中拼接的混凝土叠合板的受弯性能(挠度、裂缝、承载力、破坏形态)及承载受力机理,并利用有限元程序ANSYS对各试验板进行非线性数值模拟。结果表明,计算值与试验值吻合较好。在此基础上提出改进叠合式楼板设计的建议。
Based on the static loading experiment of four reinforced concrete floor slabs, two ordinary and two superimposed with connections, the paper studied their loading mechanism and bending performance, such as deformation, cracks, bearing capacity and fail modes. With the FEA program, ANSYS, adopted, the nonlinear numerical simulation of the slabs under the monotonous static load is done, and the corresponding results are compared with the experimental ones. Finally, proposals for superimposed slabs＇design are put forward.
