Abstract

Abstract

Cable-supported grid structure with large opening is a new roof structure proposed in recent years, and its pre-stressed construction process is quite complicated. Based on Bazhong sports center project under construction as the background, combined with the actual project, the key elements to the composition of the cable-supported grid structure with large opening were discussed.According to the actual project of tensioning scheme,the improved tension compensation method was proposed for the control values of prestress of cable in different stages of tensioning, and the finite element analysis model was established, and then the cable forces and displacement variation in different tension stages were obtained. The analysis results show that the simulated cable forces were in good agreement with the design values, and the maximum and minimum cable forces of the circumferential cables are the same after the installation of diagonal braces. At the same time, the field monitoring of construction tension process showed that the simulated value was basically consistent with the measured value. The results showed that the improved tension compensation method could effectively simulate the control values of pre-stress in cable construction in different tension stages, which had a good reference value for the prestressed tension construction of cable-supported grid structures.
