【摘要】 为研究方截面CFRP-钢管混凝土的动力性能,在试验研究的基础上,进行理论分析,得到方截面CFRP-钢管混凝土动力情况下的极限承载力。试验表明,方截面CFRP-钢管混凝土构件的动力性能更优于钢管混凝土。它的刚度退化缓慢,延性略好于钢管混凝土。且由于CFRP的作用,方截面CFRP-钢管混凝土构件耗能更多。更多还原

【Abstract】 In order to study the dynamic behaviors of CFRP-concrete filled square steel tube, a theoretical analysis is done based on the experimental study, whose ultimate bearing capacity is obtained. It is finally concluded that the dynamic behavior of CFRP-concrete-filled square steel tube member is more superior to that of concrete-filled steel tube; and the ductility of the former is slightly better than the latter; the stiffness of the former degrades slowly. The former can also dissipate more energy.更多还原
