摘要
为了研究普通钢筋混凝土梁在冲击荷载作用下的应力与位移分布规律,本文采用非线性有限元分析软件Abaqus建立了钢筋混凝土梁的有限元分析模型,结合试验测得的混凝土与钢筋材料的力学性能参数分析了钢筋混凝土梁在冲击荷载作用下应力场与位移场分布情况。结果表明,梁侧面最大拉应变区域与梁出现裂缝的区域相同,其破坏规律可用最大伸长线应变理论进行解释。
In order to study the stress and displacement distribution of ordinary reinforced concrete beams under impact loading,the finite element analysis model of reinforced concrete beams is established by using nonlinear finite element analysis software Abaqus.The distribution of stress field and displacement field of reinforced concrete beams under impact loading is analyzed by combining with the mechanical properties parameters of the concrete and steel materials.The results show that the maximum tensile strain area on the side of the beam is the same as the cracked area in the beam,and the failure law can be explained by the maximum elongation line strain theory.
