Dynamic Response Analysis Of High - Rise Building Under Wind Load

Along with the continuous innovation and the development of our country building materials, structural theory and construction technology, the changing of the way of people’s life, the speeding up of the pace of deepening reform, the accelerating of comprehensive management of the road of urbanization, the trending of population urbanization, high-rise buildings built fast from place to place. Which is attention by the people is the safety and comfort of the structure of high-rise buildings under the action of wind loads, which requires the structural engineer must use the accurate and effective method for assessing the ability of resisting the interference of wind of high-rise buildings in the designing of building structure, therefore, it has become the focus of the researching that the dynamic response analysis of high-rise buildings under the action of wind load.According to the actual situation in our country, firstly, this paper discusses and researches the theoretical method of the dynamic response of the high-rise building under the action of wind loads by combining the advanced theory of different countries.Secondly,calculating the structural dynamic response by the different theories method, analysis the structure responses of the shear force and the bending moment in different floors.Through establishing the finite element models of one engineering structure in the software of ABAQUS, and modal analysis are done on the structure to acquire of the natural frequency of vibration and the figure of vibration.Through the method of time-history analysis to structure under the environment of wind field by simulated,acquiring the maximum acceleration of time-history response, displacement of time history response on the top of the building and the shear time history response at the bottom of the building.This paper is based on the structure of the basic parameters from the modal analysis,using the different theory methods for calculation the maximum acceleration of the structure and comparing the results obtained with different theory methods to the results acquired from software,and then verify the accuracy of the calculated results from the software method,and find out some rules about shear wall arrangement reaction to dynamic response of high-rise buildings, finally put forward some suggestions about shear wall arrangement of high-rise building, and provide some references for the design of withstanding wind to practical application of the similar structure to high-rise structure.
