Sensitivity analysis can reflect the influence of design variables on constraints, and the application of sensitivity data analysis to structural design can take structural efficiency,design safety and engineering economy into account. This paper briefly introduces the principle of sensitive data analysis and takes the Skywalk, which is a long-cantilever structure with hung floor in Shimao ShenGang International Center, as a case study. Design constraints of vertical deflection and vibration serviceability are used to drive the optimal design of steel box girders and internally filled concrete using sensitivity data. It can be used as a reference for the structural design and cost control of similar projects.
