A Calculation Model for Lining Crack Width Based on Bond Slip

doi:10.11988/ckyyb.20210301

Abstract

Abstract: On the basis of the bond-slip theory,a force transmission system of “solid element to shadow node and to beam element” is proposed and applied to the separated modelling of a reinforced concrete lining structure.The stress of the stressed steel bar is calculated by finite element method,and the maximum width of crack is obtained in association with the calculation formula specified in code.Compared with test results,the feasibility of calculating the maximum crack width of lining by using the force transfer system of finite element modeling in association with code formula is verified.The research offers a novel calculation method for the maximum crack width of similar projects.

Key words: reinforced concrete lining, bond slip, force transmission system, maximum crack width, finite element
