Analysis Of Earthquake Resistance Performance Of Great Span Wire Table Structure

Generally, the people thought the great span structure restrains unnecessarily much, and the self-weight of structure is light, therefore the earthquake resistance performance is good, thus has neglected to its earthquake resistance performance research, but vision more centralisms in its stability and wind resistance. In recent years, frequent earthquake indicate that different regions of the world, affecting factors of seismic response of large span structures are complex, once the structure failure is bound to have an enormous loss, so study on seismic behavior of large span structures under earthquake action value, there are very large and very important theoretical significance.This tennis gymnasium grid structure roof in a city as a backdrop, finite element model building SAP2000, using mode superposition method and time-history analysis of response spectrum method for seismic analysis of structures, its specific contents are as follows:1.Tennis Hall dynamic characteristics analysis of long-span grid structure of the roof. SAP2000model of three dimensional finite element software structure, for modal analysis of structures, seeking the vibration characteristics of structures.2.Tennis Hall seismic response analysis of long-span grid structure of the roof. Mode-superposition response spectrum method and the method of time-history analysis of two different kinds of analysis method for seismic response analysis of structure, x+earthquake vertical seismic action and y+earthquake vertical earthquake input two different condition analysis of vertical displacement and internal force of the impact of earthquakes on structures. Concludes with a number of large-span structure analysis and design with reference to the significance of the proposal.
