【摘要】 对碳纤维布(CFRP)横向约束的混凝土矩形偏心受压柱进行了静载性能试验,测得了小偏心受压柱加固后的极限承载力,并在小偏心范围内,对不同偏心率下的CFRP加固混凝土柱受压的极限承载力和可靠度作了分析.结果表明:外贴CFRP能有效地提高小偏心受压混凝土柱的抗压极限承载力和可靠度,且其极限承载力和可靠度的提高幅度随偏心距减小而增大.更多还原

【Abstract】 Reinforced concrete rectangular columns covered with carbon fiber sheets under eccentric pressure are studied experimentally and theoretically.After the ultimate bearing capacity of the columns is tested,the ultimate bearing capacity and reliability of the reinforced concrete columns covered with carbon fiber sheets are analyzed within the little range of eccentricity.It is shown that the increase of the ultimate bearing capacity and reliability is obvious with the help of carbon fiber sheets,and the increasing amplitude is increased if the eccentric distance is decreased.更多还原
