Shandong Port Building adopts a mixed structure system of concrete-filled steel tubular column-steel beam-reinforced concrete core tube.The six inclined steel tube concrete columns at the corner are indented layer by layer from bottom to top,which echoes with the upward tightened sail shape.The structure has irregular items such as local discontinuities of floor slabs of each floor,through floor columns and height overruns.The performance-based design was carried out according to the seismic performance target of grade C.The elastoplastic analysis under rare earthquake was carried out using SAUSAGE to find out the weak parts and components of the structure,and targeted seismic strengthening measures were taken.The rigid-flexible steel-cable net curtain wall system is adopted in the air lobby,the main structure supporting the curtain wall was introduced.ANSYS was used to analyze the inclined column to straight column joints of concrete-filled steel tubular columns.The analysis results show that the seismic performance of the structure is good and meets the set seismic performance target.
