| 摘 要： | 汶川灾后重建过程中余震不断,新浇筑的混凝土结构受余震作用后钢筋产生甩动、构件出现微裂缝等现象,这些现象是否会影响钢筋与混凝土间的握裹力,是重建项目所面临的问题之一.对早龄期钢筋混凝土试件施以不同峰值加速度的振动力后即时进行拉拔试验,分析不同振动力对不同龄期的混凝土钢筋握裹力的影响.结果表明:早龄期混凝土在12h(初凝至...

| Abstract: | The process of Wenchuan reconstruction suffered ongoing aftershock.Fresh reinforced concrete was influenced by the aftershock,such as reinforcing steel swung,crack appeared on components.It is one of the problems of reconstruction whether the phenomenon would influence the bond force.After subjected to different earthquake excitations at different ages,early-age reinforced concrete specimens were studied by pull-out tests.Under the different earthquake force,bond force of bars at different ages were discuss... |
