Numerical analysis on mechanical behavior of cast-in-situ concrete cellular voided two-way plates supported

针对现浇混凝土蜂窝式空心双向板的受力性能,利用有限元分析软件ANSYS,进行了非线性数值模拟,分析结果与试验结果吻合较好,证明所建立的三维有限元模型是有效的。利用该模型,分析了现浇混凝土蜂窝式空心双向板的破坏形态以及混凝土强度等级、面层钢筋配筋率、底层钢筋配筋率、面板层厚度、空心率等因素对构件受力性能的影响,为工程设计提供参考依据。

The nonlinear numerical simulation analysis was conducted to investigate the mechanical behaviors of cast-i-n-situ concrete cellular voided two-way plates supported by ANSYS software and the calculated results were agreed well with the experimental ones.The results show that the 3D finite element analysis model is effective.The failure mode of plates was analyzed using the model.Furthermore me-mechanical behavior was studied corresponding to different para-meters such as concrete strength grade, steel reinforcement ratio on the surface, The underlying steel reinforcement ratio, panel thickness, hollow rate and the results provided some useful references for engi- neering design.
