Abstract

Abstract

The shape of the gymnasium of Luan Sports Center is similar to the famous top ten tea products "Luan Guapian", the structure of the gymnasium adopts a space specially-shaped curved steel truss structure with a span of 89.7 m. This paper first proposed three construction plans. Multi-point asymmetrical overall lifting synchronous control scheme with lifting frames in the gymnasium was determined, by comparing the technological advancement, construction safety and economic rationality. Multi-point asymmetric overall lifting synchronous control technique was developed for a space specially-shaped curved steel truss structure. The paper focused on the principle of asymmetric lifting synchronous control of lifting equipment and systems, optimize the lifting point scheme and designed the lifting frame, etc. Using MIDAS, the entire simulation of synchronous lifting and asynchronous lifting was carried out, which provided countermeasures for the overall lifting scheme. Real-time monitoring system based on mass data processing and real-time transmission of cloud platform for stadium steel structures was developed, and the actual measurement results were compared with simulations. The results showed that the multi-point asymmetric overall lifting synchronous control technique was suitable for the construction of the roof structure of the gymnasium of Luan Sports Center. The cloud platform real-time monitoring technology and numerical simulation technology could ensure the safety and reliability of the construction.
