Dynamic Nonlinear Analysis of an Out-of-Code Highrise Building

Abstract:

The most common analysis methods of complex high-rise buildings are the response spectrum analysis, elastic time history analysis, pushover analysis and etc. Meanwhile, for the analysis of those high-rises whose height is higher than 200 meters, period is longer than 4 seconds, the dynamic nonlinear analysis would be more accurate. In this paper, the dynamic nonlinear analysis was executed in use of the Perform-3D program. The results show that the maximum top displacement can meet the national codes; most tie beams and the frame beams of the upper structure yielded in the IO~IS stage and parts reached the CP stage; both the laminated columns and the frame columns had a good performance on the shear behavior; and it is also proposed to strengthen the reinforcement at the reducted storeys. By all these above, it can be judged that the structure reached the codes’ seismic performance objectives.
