| 摘 要： | 对钢筋混凝土板的截面采用分层组合模型能较好反映板受力后的开裂、应力、应变与裂缝开展等情况,并考虑混凝土在双向受力作用下的非线性性能.采用三角形薄板单元,对钢筋混凝土分层组合模型建立单元刚度矩阵.编制了非线性有限元分析程序,对所试验的复杂支承条件的钢筋混凝土板做了分析,分析结果与试验数据基本相符.有限元计算分析结果对实际应用具有参考价值.

| Abstract: | The layered and combined model is used for reinforced concrete slab section.This model may well reflect the cracking,stress,strain and crack derelopment of the slab after loading.In the paper,the nonlinear properties of concrete under biaxial stresses are considered.An analytical nonlinear finite element program of reinforced concrete slab for the whole history of loading is made by using the triangular element of thin slab.Nonlinear analyses are conducted for experimental reinforced concrete slabs with complex supporting conditions,and computed results are compared with experimental data to shown the reasonable agreement between them.The result of finite element computation is of referential value for practical application. |
