Abstract |
The interference between the lattice bar of existing LB-DECK and the bars placed at site degrades the constructability, which is pointed as a problem. HB-DECK simplified the shape of lattice bar, and converted the direction of main rebar direction to the distributing bar direction, and installed the rib on the underside of HB-DECK to increase the stiffness. The purpose of this study is to verify the structural performance of HB-DECK and cast in place concrete slab. The static load test was conducted to verify the structural performance according to Korean highway bridge design code(2015) and composite behavior of HB-DECK with Cast in Place Concrete Slab. Three-dimensional finite element analysis was carried by MIDAS FEA, and analyzed to compare the result of analysis and experiment. At a result, composite behavior was examined between HB-DECK and cast in place concrete slab, and structural performance satisfied Korean highway bridge design code(2015).
