In this study, stainless steel (STS) lining support frame capable of absorbing unexpected deformation occurring during STS lining construction and operation was developed and compared with the conventional support frame in terms of structural performance such as fatigue and energy absorption capacity. Stress distributions from finite element analysis were examined to analyze potential failure locations due to stress concentrations in the support frames. Through cyclic loading experiments, failure locations and fatigue failure cycles were compared, and energy absorption capacity was calculated.
Furthermore, comparative buckling analysis for frame bar elements was conducted for the comparison of buckling performance.
Fatigue performance and energy absorption capacity of the support frame were enhanced through improved welding details and changes in geometric shape.
