摘要
采用H型钢作为连接节点,以偏心距和后浇段箍筋形式为参数,对高钛型高炉渣混凝土装配柱、现浇柱进行了轴向偏心受压试验,研究其纵筋的力学性能。结果表明:在小偏心和大偏心的荷载作用下,装配柱受力特性、破坏形态均与现浇柱基本相同;装配柱、现浇柱的极限承载力实测值与计算值非常接近;装配柱的后浇段采用螺旋箍筋能提高其极限承载力。
H-shaped steel was used as the connection node,and the form of the post-poured section stirrups and the eccentricity were taken as parameters.Axial eccentric compression tests were conducted on high-titanium slag concrete assembled columns and cast-in-place columns to study the mechanical properties of their longitudinal reinforcement.The results show that under small and large eccentric loads,the stress characteristics and failure modes of the assembled columns are basically the same as those of the cast-in-place columns.The measured and calculated ultimate bearing capacities of the assembled columns and cast-inplace columns are very close.For the assembled columns,using spiral stirrups in the post-poured section can increase their ultimate bearing capacity.
