Abstract

Abstract

Based on the low cyclic loading experiments on specially shaped columns, it was compared that the results in terms of damage characteristic, bearing capacity, displacement and ductility, hysteretic characteristic, skeleton curve, rigidity degradation and energy dissipation.The effect of axial compression ratios on seismic behavior of specially shaped column with high strength steel bar was analyzed.It was shown that the axial compression ratio had greater influence on seismic behavior of specially shaped column with high strength steel bar.With the decrease of axial compression ratio, the deformation capacity of specially shaped column with high strength steel bar was enhanced, the ductility and hysteretic characteristic was improved and the rigidity degradation becomes slow.The bearing capacity of specially shaped column with high strength steel bar was enhanced with the increase of axial compression ratio.
