| 摘 要： | 国内外大型的有限元软件有许多,就动力非线性分析而言,大型通用有限元软件ANSYS有明显的优势.以Suidan和Schnobrich1]的试验为比照,利用大型通用有限元软件ANSYS对钢筋混凝土梁在爆炸荷载作用下的动力响应进行数值模拟,其中,混凝土采用ANSYS软件中特有的SOLID65单元类型及其对应的材料模型CONCRETE,钢筋采用LINK8杆单元和随动硬化双线性弹塑性(Kinematic Hardening Bilinear Plasticity)模型来实现.计算结果与Suidan和Schnobrich预示的响应十分吻合,并较好地模拟了梁的压碎和开裂过程.验证了该数值模拟方法以及有限元计算模型的正确性,为动载作用下钢筋混凝土梁非线性有限元分析提供了一有效方法.

| Abstract: | To nonlinear finite element analysis under dynamic loading, ANSYS is outstanding in many general large-scale finite element programs. The methods of Suidan and Schnobrich are compared, the general large-scale finite element program ANSYS was used to simulate the dynamic response of reinforced concrete beam under the load of explosion. The concrete adopts ANSYS own element type-SOLID65 and special material model-CONCRETE, and the reinforcing steel bar adopts LINK8 element type and Kinematic Hardening Bilinear Plasticity material model. The results agree with the response which Suidan and Schnobrich indicate, and the splitting and crushing course of beam is well simulated. It proves the correctness of the method and the model of finite element analysis, and provides an effective way for nonlinear finite element analysis of reinforced concrete frame under dynamic loading. |
