摘要
分别对两种含钢率及不同钢管壁厚的双钢管高强混凝土柱进行了轴压静载试验,得到了双钢管高强混凝土柱在轴压作用下的破坏过程和特点,分析了其受力机理,讨论了双钢管高强混凝土柱轴压承载力计算方法,给出了近似计算公式.
Two steel-concrete composite columns of high-strength concrete-filled double tube elements with steel tube dimension different from each other were tested about static load-bearing capacity.The paper has described the elements' breaking up characteristic,discussed the method for the columns'load-bearing capacity determination and proposed the approximately calculating formulae.
