Abstract: The construction project of Tsinghua Primary School Complex Building in Chengguan District is located in the downtown area of Lanzhou. The surrounding environment is complex, the site is small, and the structure is complicated. The mechanical performance requirements of the steel conversion box girder on the top of the basketball court are high. Through structural stress analysis, optimized design, reasonable layout of the site, and strengthening of safety management and control, the construction problems of large span, large cross-section, and super-thick steel plate components in narrow sites are solved.
Keywords: steel structures; narrow site; steel plate; box girder; welding; construction
