Dynamic Performance of the Steel Tube Filled with Steel-Reinforced Concrete Finite Element Analysis

Abstract:

In order to analyze the dynamic performance of the steel tube filled with steel-reinforced concrete under dynamic loading, the paper based on finite element approximation and inverse power of the iterative algorithm, used FORTUNE language to establish the structural dynamic analysis program. Calculated the critical loads and natural period of vibration and other data of the steel tube filled with steel-reinforced concrete column, and through curve analysis, obtained the rules of the stability of steel and seismic performance on the column from the influence parameter of slenderness ratio , steel ratio , concrete strength and etc. The results show that the slenderness ratio impacts greater than other parameters, so it must be strictly controlled within a certain range; meantime, the results also prove that improving steel ratio and reduce the strength of the concrete is not significant on the earthquake action
