| 摘 要： | 在考虑锈蚀引起的钢筋横截面损失和粘结强度下降的前提下,建立锈蚀钢筋混凝土梁的有限元分析模型。钢筋单元采用三维杆单元,混凝土单元采用8节点实体单元,钢筋与混凝土之间的粘结单元采用非线性弹簧单元。利用大型有限元ANSYS分析软件,对锈蚀梁的受力性能进行模拟分析,模拟结果与试验方法结果吻合,说明采用非线性有限元方法分析锈蚀梁受力性能正确有效。

| Abstract: | The section loss of steel bars and degradation of bond intensity were taken into consideration in this study.The three-dimensional rod element was taken as the steel bar element,the eight-node solid element as the concrete element,and the nonlinear spring element as the bonding element between the steel bars and concrete.The bearing capacity of the reinforced concrete beam with corroded steel bars was simulated by making use of the large-scale finite element software ANSYS.Similarity of the ANSYS simulation... |
