Abstract

Abstract

Seismic performance of traditional steel reinforced concrete ( SRC) columns was indistinctively improvedrelative to RC columns in that I and H shaped steel couldn't supply enough constraint for core concrete, henceapplication of the composite columns is limited in high earthquake intensity region, and two new type steel reinforcedconcrete columns are proposed based on this background. Numerical models of five specimens which have beencompleted are established using nonlinear finite element method, and accuracy of the numerical analysis is verified bycomparing ABAQUS results with the experiment of five new columns under low cyclic reversed loading, with focus onhysteretic curves, skeleton curves and stress state of steel. In addition, effects of axial compression ratio, concretestrength grade and stirrup spacing on seismic performance of new columns are analyzed, and limited values of axialcompression ratio for three seismic grades are proposed, which supply a reference for standard revision andengineering calculation.
- new steel reinforced concrete columns,
- numerical simulation,
