【摘要】 采用试验与计算两种方法,对新旧混凝土结合的Z型粘结试件受力与破坏状态进行了研究。结果表明,模型尺寸引起的附加力偶对Z型粘结件极限荷载有较大影响;粘结面的结合强度决定了试件的破坏形式;利用Z型粘结试件测定新旧混凝土结合面抗剪强度值需要相应的修正。更多还原

【Abstract】 Using two methods of the test and calculation, the stress and destruction states of fresh and old Z-type adhesive specimens were studied. The results show that: additional couple have a greater impact on the ultimate load of the specimen; Combined strength of the adhesive surface determines the form of damage; Shear strength of the adhesive surface need amendment according to the test results.更多还原
