【摘要】 通过单调加载静力试验,对3个植筋连接的新旧砼试件进行研究,考虑植筋直径、埋深、和箍筋率等因素对新旧砼结构的抗剪承载力的影响。通过试验,研究植筋连接的新旧砼结构的破坏形态和极限荷载,从而表明,箍筋率的增加能明显的提高结构的抗剪承载力。更多还原

【Abstract】 3 test samples of structure consisting of existing and new concrete with planting bar connection test had been investigated by monotonic static loading. Some factors which(including planting bar diameter, burial depth, stirrup ratio, etc)should be taken into consideration, had some influences on shear bearing capacity of old and new concrete structure. The failure pattern and the ultimate load of the structure was investigated by test, which reveal that the increase of stirrup ratio can significantly improve the shear bearing capacity of the structure.更多还原
