Development status of steel structure design and construction methods

The specifications of steel structure design are continuously improved, which also provides an effective guarantee for the designers of China's steel structure industry to improve their professional literacy, and various forms of steel structure design software suitable for the use of computer technology have been gradually developed. In recent years, China has made great progress in the construction technology of steel structure, such as the lifting slip technology with a large span, the microcomputer hydraulic overall lifting technology with intelligent system, and the software simulation technology used in the construction and installation of steel structure. Among the existing steel structure buildings, there are many typical successful cases, such as the twin frame slip in the passenger terminal of Baiyun International Airport in Guangzhou, and the roof slip in the sports exhibition center in Harbin. Through 3D real-time dynamic simulation, all kinds of construction assembly, lifting test and even optimization construction process are basically completed, and problems existing in the construction scheme can be detected in advance and modified in time, eliminating the procedure of site trial assembly and achieving twice the result with half the effort.
