| Abstract: | Guangzhou TianYu Building is a steel reinforced concrete frame-reinforced concrete core walls hybrid structure system.It is divided into two independent structural systems——north and south tower by seismic joint.South tower is 186.5 meters high and north tower is 159.5 meters high.North and south towers’ aspect ratio and the ratio of the total width of the core tube to the height of core tube are all beyond normal limits.In order to provide seismic resistant design basis for this high-rise hybrid building,Earthquake Engineering Research & Test Center of Guangzhou University conducted(1/30) scale model shaking table test,and used finite element software ETABS for modal analysis and time-history analysis.Test and analysis results show that the structural system has sufficient horizontal stiffness.On the whole,the structure meets the seismic requirements.In major earthquake,the relative displacement of the south and north towers and the story drift angle are so large that north tower and south tower would collide.It is suggested that increasing the distance between the two towers suitably or taking energy dissipation measures should be done. |
