Notes:
The horizontal press performance of column is deteriorated because of special-shapedsection. Moreover, because the antiseismic performance of columns is worse, it is only used inregions where seismic intensity is lower. So the main problem is to enhance the ductility. This teststudy on mechanical performance has been carried out through fourteen SRCTSSC and RCTSSC.The study focuses on the impact of test axial pressure ratio(nt), hooped reinforcement ratio(ρv),shear span ratio(λ) and steel ratio(ρss) to the shear strength and the antiseismic performance ofSRCTSSC. It can be concluded that the shear strength of SRCTSSC is increasing with theincreasing of nt and ρss , but the degree of increasing is small when nt is a certainty value, and thatthe shear strength of SRCTSSC is decreasing with increasing of λ; The shear resistance formula ofT-shaped column is derived through tests, the calculated results are in correspondence with those ofthe tests. It also can be concluded that the hysteretic loops of the SRCTSSC are full and thehysteretic behaviors are improved and that the displacement ductility is increasing with increasingof ρv and ρss , but decreasing with the increasing of nt and the degree of variety in high axial pressureratio is larger than in low axial pressure ratio. If steel bars are added, the shear strength anddisplacement ductility of SRCTSSC is increased in a large degree, and the capacity of energydissipation is also enhanced. This test, for applying the special-shape column to higher intensityregion, has the certain instructive significance
