高强钢筋混凝土偏压柱的裂缝宽度试验研究
The Crack Width Test of Reinforced Concrete on Bias Component
【摘要】 通过9根HRBF500钢筋混凝土偏心受压柱和1根HRB400钢筋混凝土偏心受压柱进行单向加载试验研究分析,并与受弯构件试验裂缝宽度情况进行对比,可知偏压构件的裂缝宽度试验值与实测值之比要相对小于受弯构件的比值,应将规范公式中的钢筋混凝土偏压构件受力特征系数进行折减,提出了偏压和受弯构件受力特征系数的建议值.
【Abstract】 Through the experiments of nine eccentrically loaded columns with 500 MPa steel bars and one with 400 MPa bars,compared with the experimental cracks of the flexural members,it is known that the ratio between the experimental and measured crack width values of the eccentrically loaded columns is lower than that of the flexural members,therefore the force characteristic coefficient of the bias members should be reduced and the recommended value of the force characteristic coefficient of the bias and the flexural members is provided.
