Experimental and Analytical Studies for the Effect of Embedded Pipe Directions on Flexural Behaviors of Hollow Core Slab with PCM

PCM을 포함하는 중공슬래브의 배관방향에 따른 휨거동 평가를 위한 실험 및 해석 연구

The purpose of this study is to investigate effect of directions of pipe for thermal activation on flexural behaviors of hollow core slab embedded with PCM. The study includes experimental and analytical methods. For former method, specimens having pipes in two different directions and a specimen without having pipe is fabricated and subjected to four-point loading system. From the experiments, load-deflection curves and crack propagations show that there is no significant differences between the specimens. Analytical results from the finite element models having same conditions as experiments show that the modeling method is able to capture structural and mechanical behaviors of hollow core slabs with PCM. The validated modeling method is also used to simulate hollow core slab including heat transferred from the pipes. The latter analysis shows that the hollow core slab with pipe can be considered as the slab without pipe, regardless of heating and directions of pipes.
