蜂窝状钢骨混凝土不对称十字形截面柱正截面承载力试验
|
摘要
设计了2根蜂窝状钢骨混凝土不对称十字形截面异形柱试件,并进行双向偏心压力作用下的试验研究,以揭示蜂窝状钢骨混凝土不对称十字形截面异形柱的工作机理、破坏形态并计算了极限承载力.试验结果表明:蜂窝状钢骨混凝土不对称十字形截面异形柱的破坏形态与普通钢筋混凝土构件相似,计算的横截面平均应变基本符合平截面假定,腹板开洞有利于提高混凝土与钢骨的协同工作能力,钢骨腹板开洞基本不影响蜂窝状钢骨混凝土不对称十字形截面异形柱的极限承载力.
Two honeycomb-type steel reinforced concrete(SRC) asymmetrical cross-shaped section columns were tested under biaxial eccentric loading to study the bearing behavior,the failure patterns and the column ultimate bearing capacity.Test results show that the failure mode is similar to reinforced concrete structure and the average strain of plane cross-section is basically coincident with the hypothesis.Opening holes on the web plate are advantageous to improve the interoperability between the steel and the concrete,and the ultimate bearing capacity of honeycomb-type SRC asymmetrical cross-shaped section columns is almost not effected by the opening hole on the steel web plate.
