Numerical Study on Long-term Behavior of Flat Plate Subjected to In-Plane Compressive and Transverse Loads

바닥하중과 압축력을 받는 플랫 플레이트의 장기거동에 대한 해석적 연구

Numerical studies were carried out to investigate the long-term behavior of late plates in basement, subjected to combined in-plane compressive and transverse loads. For the numerical studies, a computer program of nonlinear finite element analysis was modified by adding function of creep and shrinkage analysis. This numerical method was verified by comparison with the existing experiments. Parametric studies were performed to investigate the strength variations of flat plates with three parameters; 1) loading sequence of floor load, compression and time 2) uniaxial an biaxial compression and 3) the ratio of dead to live load.
