摘　　要：文中利用数值模拟手段对整体浇筑式和装配式墙板不同节点处的变形及力学时程响应进行分析。结果表明,随着时间的推移,整体浇筑式第一层角点及第二层角点处的位移表现为振荡的变化规律,位移时程响应曲线存在多个峰值,整体浇筑式第一层及第二层角点位置的位移时程响应曲线的一致性较好。装配式第一层角点及第二层角点处的位移表现为振荡的变化规律,位移时程响应曲线存在多个峰值,然而,三个装配式角点位置的位移时程响应曲线的一致性相对较差。装配式第一层角点处的剪力同样为振荡的变化规律,曲线存在多个峰值,且装配式第一层角点位置的剪力时程响应曲线一致性较差,节点1-1的剪应力值远远高于节点1-3和1-6位置的剪应力。对于节点1-3,峰值剪应力基本稳定,维持在约3416Pa。Numerical simulation was used to analyze the deformation and mechanical time-history response at different nodes of integral cast and assembled wall panels.The results show that with the increase of time,the displacements at the first layer and the second layer of the inte-gral pouring type are oscillatory,and there are many peaks in the response curve of displacement time history.The response curve of displace-ment time history of the first and second layer of the integral pouring type has a good consistency.the displacements at the first and second lay-er corners of the assembled type show oscillatory changes,and there are multiple peaks in the response curves of the displacement time history.However,the consistency of the response curves of the three assembled corners is relatively poor.The shear force at the corner of the first layer of the assembly is also oscillatory,and there are multiple peaks in the curve.Moreover,the time-history response curve of the shear force at the corner of the first layer of the assembly is poor in consistency,and the shear stress value at nodes 1-1 is much higher than that at nodes 1-3 and 1-6.For nodes 1-3,the peak shear stress is basically stable,maintaining around 3416 Pa.
