고력볼트로 체결된 T-stub의 지레작용력 및 접촉력 예측모델

초록

High strength bolted T-stub under a tensile load is affected by prying action force and contact force between element. If design formulas considering prying action force and contact force does not propose, T-stub under a tensile load is possible to destroy on smaller strength than predicted design strength. Therefore, in order to prevent it, Through many studies until now, prediction models for prying action force and contact force between element of High strength bolted T-stub have been proposed. However, in Korea, there have not been the proposal for a design formula considering it. Therefore, this study propose a more accurate improved prediction model than prorosed model by applying the three-dimensional nonlinear finite element analysis.
