低粘结高强钢筋混凝土柱抗震及恢复性能研究
This paper represents the experimental results of four circular fly ash concrete (FAC) columns which wasconstructed and tested to study the influences of the types of longitudinal rebars and transverse reinforcementmethods on seismic behaviors under reversed cyclic loading. The test results indicated that specimens withhigh strength rebars having poor bond property exhibited smaller residual deformation and more stableseismic resistances than the specimens reinforced by conventional high-strength deformed rebars. Thespecimens confined by steel plates behaved not only higher lateral resistance but also less residualdeformation than the specimens confined by conventional spiral hoops. The self-centering capacity of RCcolumn primarily depends on the yielding condition of the tensile longitudinal bar. The analytical methodwhich can consider the steel bond slip is capable of reasonably evaluating the seismic responses of concretecolumns reinforced by steel with a variable bond property, however, should be further calibrated to predictthe residual drift.
