In this study, the damage-plasticity model for concrete that was verified by the model experiment was used to calculate the damage to a spiral case structure based on the 117 varick street damage mechanics theory.The concrete structure surrounding the spiral case was simulated with a three-dimensional finite element model.Then, the distribution and evolution of the structural damage were studied.Based on investigation of the change of gap openings between the steel liner and concrete structure, the impact of the non-uniform variation of gaps on the load-bearing ratio esab miniarc rogue between the steel liner and concrete structure was analyzed.

The comparison of calculated results of the simplified and simulation algorithms shows that the simulation algorithm is a feasible option for the calculation of spiral case structures.In addition, the shell-spring model was introduced for optimization analysis, and the results were reasonable.
