摘　　要：利用大型通用有限无软件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单元类型和专门的材料模型CONCRETE ,钢筋采用LINK8杆单元和随动硬化双线性弹塑性 (KinematicHardeningBilinearPlasticity)模型来实现 ,并与Suidan和Schnobrich[1] 的方法进行比较 ,计算结果与Suidan和Schnobrich预示的响应十分吻合。Large-scale multi-purpose finite element program ANSYS is used to simulate the dynamic response of reinforced concrete beam under blast loading.ANSYS own element type—SOLID65 and special material model—CONCRETE are adopted fot the concrete and LINK8 element type and kinematic hardening bilinear plasticity material model are adopted for the reinforcing steel bar.Compared with Suidan and Schnobrich's [1] method,the results tallies with the response which Suidan and Schnobrich has indicated.
