Performance-Based Design and Table Test Study on Hybrid Structure Combined with outside Steel Grid and Inner Reinforced Concrete Tube

Abstract:

With the hybrid structure including outer steel grids and inner reinforced concrete core tubes (RCCT) as the background, the key problems involved in the performance-based structural design are analyzed and the table test is conducted. Anti-seismic and stability indicators are defined based on the structural characteristics; The research on seismic response is made through elastic-plastic time-history analysis and verified through the table test; The overall stability of the outer steel grids and the anti-collapse capability following the ineffectiveness of some key components are analyzed. Results show that the structure in which the outer steel grids are connected with internal steel frame and RCCT is practicable, and the said three systems can work together effectively; The time-history analysis shows that the structure is weak at the elevation of 5-15m but can still meet the expected anti-seismic target under rare earthquakes. The space steel structure features sound stability and high redundancy, which ensures the structure will not collapse even if several key components are damaged.
