Seismic Design and Deformability of Interior flat Plate-Column Connections Subjected to Unbalanced Moment

불균등 휨모멘트를 받는 플랫 플레이트-기둥 접합부의 변형능력과 내진설계방법

Flat Plate structures subjected to lateral load are susceptible to the brittle failure, therefore deformability of plate-column connections should be ensured to resist against earthquake. However, according to previous study, existing experiments overestimate the deformability of connections and current design provision do not accurately explains them. In the present study, parametric study using nonlinear finite element analysis was performed. Based on the numerical results, seismic design method considering the deformability of connections was developed.
