配置600 MPa级钢筋的混凝土十形截面柱抗震性能试验
Experimental on Seismic Behavior of Cross-shaped Concrete Columns with 600 MPa-grade Reinforcing Bar
摘要
Abstract
Six special-shaped concrete columns with 600 MPa-grade reinforcing bar and one common special-shaped concrete column with HRB500 reinforcing bar were tested under cyclic loading. The influences of stirrup spacing and axial compression ratio on failure characteristic,bearing capacity, ductility performance,hysteretic properties,energy dissipation capacity and rigidity degradation were analyzed. And applicability of 600 MPa-grade reinforcing bar in special-shaped columns was studied. The results show that bending-shear failure was occurred for special-shaped columns under the combined action of compression,bending and shear. Special-shaped columns with smaller stirrup spacing ehibit better displacement ductility and better energy dissipation capacity. Axial compression ratio has a great effect on ductility performance. With the increasing of axial compression ratio,the displacement ductility decrease while the bearing capacity of special-shaped columns increases. Special-shaped columns with 600 MPa-grade reinforcing bar show better bearing capacity compared with special-shaped column with HRB500 reinforcing bar and exhibit good sesmic performance.关键词
