摘要
常见界面粘贴滑移模型包括双曲线模型、双线性模型和三线性模型,对静载下CFL与混凝土粘贴界面的受力形式与破坏形态进行分析,在CFL-混凝土粘贴界面破坏过程中,当粘贴界面相对滑移量大于s_0分割点时,CFL板材与混凝土发生相对滑移,界面内部开始损伤;当粘贴界面相对滑移量大于s_u分割点时,界面损伤破坏。
Common interface bond slippage models include hyperbolic curve model, bilinear model and trilinear model. Forces and failure forms at bond interface between CFL and concrete under dead load were analyzed. During the failure of CFL-concrete bond interface, there was relative slippage between CFL plate and concrete and internal failure will happen in the interface if the relative slippage of bond interface is greater than S0 breakpoint; the interface failure will happen if the relative slippage of bond interface is greater than Su brealqaoint.
