进行了9根两面高温的钢筋混凝上偏心受压构件的试验.结果表明,不均匀高温下的钢筋混凝土偏心受压构件的极限承载力并不一定随偏心距的增加而下降,而是存在一个偏心距不等于零却有最大承载力的极强偏心距点,此点两侧随偏心距的增加构件的极限承载力下降.文中还给出了构件的各种表观现象、破坏形态、侧向挠度和轴向变形等性能随试验温度的变化规律.
Nine high temperature reinforced concrete eccentric compression members were tested.The results show that the ultimate bearing capacity of reinforced concrete eccentric compression members under inhomogeneous temperature does not necessarily decrease with the increase of eccentricity distance but exists An eccentricity is not equal to zero but has the maximum bearing capacity of the extreme eccentricity point, both sides of the point with eccentricity increases the ultimate bearing capacity of components decreased.The article also gives a variety of components of the apparent phenomena, damage morphology, side The deflection and axial deformation and other properties with the test temperature changes.
