为了提高建筑底层装配式竖向结构耐压能力,需要进行竖向结构压力实时监测,提出一种基于自恢复耗能支撑弹性模量分析的建筑底层装配式竖向结构压力监测方法.构建建筑底层装配式竖向结构的应力载荷分布模型,采用边界刚性约束分析方法进行建筑底层装配式竖向结构压力的荷载-挠度特征分析,提取竖向结构的极限承载力峰值,采用轴压承载力动态监测的方法进行装配式竖向结构压力的弹性模量测试,结合应力-应变关系进行建筑底层装配式竖向结构的弹性比例应变限值测试,采用自恢复耗能支撑弹性模量分析方法实现压力动态监测.仿真结果表明,采用上述方法能动态监测建筑底层装配式竖向结构压力,提高建筑底层装配式竖向结构的抗压能力和屈服响应.
In order to improve the compressive capacity of the fabricated vertical structure, it is necessary to monitor the pressure of vertical structure in real time. This article focuses on a method to monitor the vertical structural pressure on the ground floor of fabricated buildings based on the elastic modulus analysis of self-recovery energy dissipation support. First of all, the stress-load distribution model of vertical structure was constructed. The method of boundary rigidity constraint analysis was used to analyze the load-deflection characteristics of vertical structural pressure on the ground floor of fabricated buildings. Then, the peak value of ultimate bearing capacity of vertical structure was extracted. The method of dynamic monitoring of axial compression bearing capacity was used to test the elastic modulus of fabricated vertical structure. Based on the stress-strain relationship, the elastic proportional strain limiting value of vertical structure on the ground floor of fabricated buildings was tested. Finally, the dynamic pressure monitoring was achieved by the elastic modulus analysis method based on self-recovery energy dissipation support. Simulation results show that the proposed method can dynamically monitor the vertical structural pressure on the ground floor of fabricated buildings and improve the compressive capacity and yield response of the vertical structure.
