본 연구에서는 철근콘크리트 프리캐스트 대형판의 접합부 설계방법 및 해석방법에 대해서 연구를 수행하였다. 접합부의 설계방법은 수평접합부와 수직접합부의 구조적 거동에 대한 안정성 및 일체성을 확보하기 위한 설계법을 제시하였고, 접합부의 해석은 강체스프링 모델에 의한 탄소성해석을 수행 하였다.

The stability and integrity of precast large panel structures are analyzed with nonlinear mathematical model considering the inelastic properties of horizontal joints. In this research, an analysis for cyclic loading test was carried out by the macro model that idealized the horizontal joints as inelastic-nonlinear spring systems. As a results, the strain hardening ratio of shear slip element was estimated as about 0.05%- 0.2% of initial shear stiffness. And under lateral load, the rocking motion due ti overturning moment was dominant rather than shear slip motion in the behavior of precast structures.

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.
