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.
