The Analysis of the Composite Beam in the Earthquake Response by the Finite Element

Abstract:

By large-scale finite element software ANSYS, the seismic response of large span steel - concrete composite beams were analyzed, to get the change rule of the deflection and stress of the design. And analysis of the extension of design parameters for influence factors, such as concrete grade, reinforcement ratio, the height of steel beam, is to get their effect of the seismic responses of the composite beam deflection and stress, and provide powerful basis for optimal design of composite beams. For the model in the interface by setting the three direction spring element to simulate the interface slip and vertical uplift, and choosing three directions of EI Centro seismic wave including relatively rich spectrum as input, the result of analysis is relatively accurate.
