Evaluation of Structural Behavior of Precast-Concrete Column and H-Beam using Non-linear Finite Element Analysis

비선형 유한요소해석을 이용한 PC 기둥-H 형강보의 구조거동 분석

Nonlinear finite element analysis is conducted to predict the structural behavior of precast concrete column and steel beam connected by using bolted connections. The Nonlinear FEM program is based on the modified compression field theory which has good accuracy in the concrete structures. The link element is properly used to model the discontinuity between precast concrete column and steel beam. Predictions from the proposed model are compared with experimental results and it is concluded that structural behaviors of the composite structures, such as strength capacity, crack pattern and failure mode, can be predicted quite successfully.
