Abstract

Abstract

For small and medium-sized steel structure sports venues, a prestressed construction technology is proposed to reduce the impact of the construction process on the structural state and to fully utilize the characteristics of the steel structure itself, which has a certain elastic deformation range. The main feature of the process is to first construct the main truss, followed by the roof grid. After the main truss is completed, it is pulled down to a specific position (within its elastic range) using a pull-down cable, and the roof grid is connected to it. After all connections are completed, the tension in the pull-down cable is gradually released in stages. After the pull-down cable tension is released, the main truss experiences a certain degree of rebound. During this process, the roof grid forms a prestressed structure, and a stable whole is formed between the main truss and the roof. A numerical simulation was performed to analyze the construction process and determine the optimal prestressed construction scheme.
