Abstract:The total height of the tower one of Shum Yip Upperhills is 388m. Rigid connection of steel reinforced concrete coupling beams are installed between each of the 8 mega columns and the corewall to replace the reinforced layer outriggers. The new structural system formed by belt trusses + peripheral parallel double-bending-resistance steel frame beams + steel reinforced concrete coupling beams + giant frames + corewall can effectively resist the huge lateral forces caused by earthquake actions and wind loads. A performance-based seismic design method was adopted. The structure performance and component damage under different seismic levels were verified by shaking table tests, and appropriate structural strengthening measures were taken based on the analysis and test results to make the seismic performance of the overall structure and each component can achieve the expected seismic performance goals. This structural system can provide a reference for similar super high-rise buildings with the building height of more than 300m to avoid setting up outriggers.

Keywords:mega frame-corewall structure; steel reinforced concrete coupling beam; performance-based seismic design; shaking table test
