Analysis Different Taper Hybrid System Under The Influence Of Wind Load And Seismic

Wind load design has become the main control reason in the structure with the building structure towards high ,big , small ,long flexible project development .The research of wind-induced response and its equivalent wind load of the structure is particularly important .Considering development trend of the structure in future ,the form of structure will be more diversified and complicated.In this paper,It establish the hybrid structure models under different taper by the finite element software ANSYS,make static analysis and dynamic analysis.It is both the displacement curves along the height and modal analysis,and analysis of earthquake action in the structural.Can know the hybrid structure of different taper under the action of wind load,more stable with large taper and the structure will become increasingly stable with the taper increases.Hope that it can provide help to shape design for the structure in the future .This article made the following works:1) It establish four hybrid structure models of different tapered under wind loads by the ANSYS software;2)It analyze modal of the four establishment models,obtain the natural frequencies and mode shapes in order to study the dynamic performance by the ANSYS software;3) It make static analysis of the four models, including the X direction and Y direction node displacement of structure and the displacement curve along high degree of direction,in order to research deformation under the wind load by the ANSYS software;4 ) It make dynamic analysis for structural comparing the nodal displacement and axial force of the structure,make nodes and the displacement curves and the dynamic axial force curve, then study the mixed system on the seismic performance of structure by the ANSYS software.The results show that:1) Through the analysis of wind loads, can know the relative taper model, the displacement of their nodes was reduced; at the same time their period is change along with the changing taper;2) The maximum displacement in X is greater than Y, Z in seismic studies on the structure. The internal forces showed a decreasing trend with the different taper.
