| 摘 要： | 城市桥梁建筑景观需要使许多高架桥桥墩设计成异形构件,而一般的梁单元方法只能近似分析其力学性能.以天津东旭路桥的异形桥墩为工程实例,利用ANSYS的三维实体单元,正确仿真异形桥墩的整体结构,分析其在恒载和组合工况作用下的三维应力分布情况;并利用ANSYS的钢筋混凝土非线性分析功能,计算桥墩混凝土开裂区的钢筋应力,分析混凝...

| Abstract: | Many piers of viaduct bridges are designed to special shape due to demands of urban bridge's architectural landscaping,but the classic beam element method can only obtain their approximate structural analysis results.Taking the shaped pier of Tianjin Dongxu Road Bridge for example,this paper precisely simulated the whole structure of shaped pier with ANSYS's 3D solid element, and analyzed its 3D stress distribution under dead loads and combinations.Furthermore,the paper adopted the reinforced concrete nonli... |
