【摘要】 针对地震载荷作用下混凝土梁柱节点结构,提出了一个多屈服面强度模型。通过详细定义加载—卸载—再加载过程,该强度模型可以处理弹性变形、非相关流动、硬化和混凝土损伤。数值计算表明,该模型能够很好地模拟地震载荷作用下混凝土梁柱节点的变形行为。更多还原

【Abstract】 In light of concrete beam-column joint structure under seismic load,the paper puts forward the multiple yield surface model.Through specifically identifying the loading-unloading-reloading process,the strength model can deal with elastic deformation,non-relevant flow,hardening and concrete damage.The numerical calculation shows that the model can better simulate the concrete beam-column joint deformation performance under the seismic load.更多还原
