【摘要】 通过对设置了外伸短梁的2榀钢纤维无粘结预应力扁梁框架以及用来对比的普通混凝土扁梁框架的拟静力试验,讨论了钢纤维对梁、柱的破坏形态、框架滞回曲线、钢筋的应变以及钢筋和混凝土之间的粘结滑移的影响更多还原

【Abstract】 Based on the experiments of two unbonded-prestressed wide-beam frames with steel fiber concrete and one with conventional concrete for comparing under low reversed cyclic loading, influenced of steel fibers to the failure pattern of beam and column, hysteresis loops, strain of reinforcement and bond slipping between the bar and concrete have been discussed.更多还原
