| 摘 要： | 基于纤维模型有限单元柔度法,考虑轴向、弯曲和剪切效应,对钢筋混凝土结构承受单调荷载作用进行非线性分析.应用多轴应力状态下的塑性应力-应变关系理论,在单元模型中考虑了弹塑性区域剪切变形对单元弹塑性刚度的影响,建立能够考虑梁柱非线性剪切变形的纤维单元在复杂加载历史中的切线刚度矩阵.在所建立的截面刚度矩阵中,剪切变形和轴向、弯曲变形不耦合,而剪切和弯曲力在单元层面耦合,且在梁单元上满足力的平衡关系.将计算结果和钢筋混凝土柱的加载试验结果相比较,验证了模型的有效性. |

| Abstract: | The RC structure under monotonic loading was analyzed,including axial bending and shear effects.Based on the plastic stress-strain theory of multi-axis stress state,and taking into account of shear deformation in plastic region to stiffness of the element,the tangent flexibility matrix which accounts for nonlinear shear deformation of column element during the complex loading was set up.Shear deformations are thus uncoupled from axial and bending effects in the section stiffness,but shear and bending forces... |
