Recent Advances and Engineering Practice in High-Rise Steel Structure Building

Steel structure is known for its advantage of high strength, light self-weight, good seismic performance, fast construction speed, and green sustainable development, which had a rapid development in the 30 years after the reform and opening up. Over the past decade, the proportion of steel structures used in high-rise buildings such as residential buildings and high-rise industrial buildings has significantly increased. Various steel structure systems have also seen new developments in super high-rise buildings. The design for seismic performance, energy dissipation and shock absorption technologies, and the promotion of high-performance steel materials have enabled steel structures to exert greater advantages in high-rise construction. However, compared to foreign advanced technologies in high-rise buildings, there is still a significant gap in material performance, structural design methods, and economic aspects of steel structures in our country. It is necessary to promote interaction across the entire industry chain and further develop related technologies.
