Nonlinear Finite Element Analysis for the Precast Concrete Large Panel Subassemblage subjected to Horizontal Force

수평하중을 받는 프리캐스트 콘크리트 대형 판넬 부분구조의 비선형 해석

During earthquakes, the joints provide a principal means for energy dissipation, and these are also responsible for introducing a nonlinear behavior to the overall building system, while large panels remain in the elastic range. In analysis for the precast concrete large panel system, it is difficult to make a general analysis for their behavior because of differences in joint details. Therefore, in case of presence of vertical joints, it is more difficult because of the interaction between the horizontal joints and vertical joints, In this study, a nonlinear finite element analysis is performed using the gap element, friction element, and concrete material model, and the results are compared with the experimental results.
