Finite element analysis on seismic resistance of precompressed steel-reinforced-concrete columns
Abstract：Based on a steel concrete column,a new column form named steel concrete column of precompression chamber was presented. The engineering~ significance and recent researches of the steel concrete column of precompression chamber were introduced. The article applies the ANSYS finite element analysis software, through the low-week-repeated-load experiment of 9 steel concrete columns of precompression chamber for different concrete intensity ranks,different steel pre-compressed ratios and different axis presses ratios, and obtains the pre-compressed ratio destruction shape and hysteresis curve under above different situations. It was concluded that the steel concrete column could improve its aseismic performance,but the performance will be reduced when improve its concrete intensity and part axis press ratio.
