고강도 T형강 합성트러스 실험

Most of the truss are designed without considering the composite effect between slabs, because design rules for using composite truss does not decribed in KBC2009. The objective of this experiment is to verify composite effect of composite truss made of 600MPa class steel. Two composite truss specimens and two steel truss specimens were made for the tests. The experiment were conducted under concentrated central loading and two point loadings on simple supported at each side, with the oil jack covering up to 490kN. Composite effect between concrete slabs is ascertained from test result.
