Abstract:Xinzhou Building adopts large-span steel reinforced concrete transfer truss and suspended steel frame to meet the architectural requirements of function and space well. The design concept and technical difficulty, the main calculation and analysis results and structural measures of all components of the selected structural system were emphatically introduced. The design method of this project can provide new way for structural design to meet the architectural requirements of lifting the ground floor and column-free spaces. The suggestions can provide references for design of similar projects.

Keywords:enlarged-base structure; structural system selection; steel reinforced concrete; concrete transfer truss; suspended steel frame; elastic time-history analysis
