recent days, Complex Steel Structure Construction Force Research and ApplicationWhich is exploited by Sinoconst group and Tsinghua University was awarded second-class national technology prize. This project already won first-class technology progress prize issued by Education Department.

    Complex Steel Structure Construction Force Research and Application is mainly researched complex steel structure stress or time variation in construction, research and control structure form, boundary condition, loading, environmental function, material character so as to ensure engineering safety and quality. This project is mainly contained three new technologies which are complex steel structure substep deformation pre-adjusting technology, steel structure roof whole rise integrated construction model, analysis on systematic technology and complex initial stress steel structure construction tensile technology and deviation controlling technology. The achievement has been reached domestic top and international advanced level. Above researched achievement has already applied on lots of significant projects such as national stadium (bird nest), Shenzhen Baoan stadium, CCTV new address main building, capital airport A380 plane hangar, Macao multi-functional stadium, new white clouds airport terminal and hangar, Guangzhou new stadium, Tianjin Taida citizen culture hall and etc, and obtain sound technical economic benefit.
