Simulation of Wind Load Response of Super Tall Building Structures under Load Action
Different from ordinary buildings,with the increase of height,the basic natural vibration period and flexibility of the structure of super high-rise buildings increase,while the damping ratio decreases.In order to improve the stability and safety of the structure of super high-rise buildings,this paper proposed a method of analyzing wind load response.Based on random vibration theory,a motion equation of irregular structure under wind load in super high-rise buildings was established,and then structural displacement change was analyzed.Moreover,the wind effect of the building's irregular structure was analyzed through static wind effects and dynamic wind effects.According to the analysis results,the wind load response analysis of the building structure was completed using the load reverse recognition algorithm and discrete Kalman filter theory.Simulation results show that the proposed method can accu-rately obtain the turbulence degree,wind speed time series,and wind center trajectory of the irregular structure of su-per high-rise buildings,indicating that the accuracy of the simulation analysis result of wind load response is high.
