|
摘要
为研究方钢管混凝土的抗震性能,对以往学者在钢管混凝土柱延性影响因素方面的研究进行了总结,指出了钢管混凝土延性的影响因素主要有含钢率、混凝土强度等级、轴压比、长细比和钢材的屈服强度等几种,明确了延性随各种影响因素的变化规律,并对影响机理进行了分析,以达到改善方钢管混凝土柱延性的目的。
In order to study the anti-seismic performance of the square steel tubular concrete column,the paper sums up the research on the influencing factors which influence the ductility of the steel pipe concrete by experts previously,points out the influencing factors of the ductility of the steel pipe concrete include the steel ratio,the grades for concrete,the axial-load ratio,the slenderness ratio,the yield strength,identifies the change law for the ductility along with the influencing factors,and analyzes the influential mechanism,so as to improve the ductility of the square steel tubular concrete column.
