WELDING TECHNOLOGY OF LOADING STEEL PLATE SHEAR WALL IN SUPER HIGH-RISE STEEL STRUCTURE OF JIN TOWER IN TIANJIN

The steel plate shear wall (SPSW) in core tube of the Tianjin Jin Tower project is the highest steel plate shear wall (SPSW) on the world nowadays. The corresponding welding techniques on SPSW of the Tianjin Jin Tower, which bearing with a structure load, were summarized and expatiated from various aspects, i.e. the design schemes analysis of welding, optimization design of welding joints and welding procedures, welding stress monitoring and quality analysis, the selection of welding materials, and the vibrating string stress sensor was attempted to apply in the process of welding stress monitoring, these monitoring data then were used to improve the control measures of welding stress again. It was found that avoiding weld cracks as well as dealing and analyzing welding defects in time were emphasized during the process of constructing the SPSW of Tianjin Jin Tower project.
