Abstract:Jiantao Plaza  is a 72m-span connected structure composed of two tower buildings and steel truss connections. There are many out-of-code cases in the project, such as irregular torsion, discontinuous floor, sudden change in stiffness, complex connections and so on. The overall structure analysis was carried out for the out-of-code cases. The analysis results show that the parameters meet the requirements of the code. The key technical problems in the design of engineering structures were comprehensively introduced, including construction simulation analysis, collapse resistance analysis, joint analysis, temperature effect analysis, buckling analysis, comfort analysis and dynamic elastic-plastic analysis.

Keywords:large-span connected structure; support joint; construction simulation; collapse resistance; temperature effect;  comfort level
