STRUCTURAL PERFORMANCE OF WOOD-CONCRETE COMPOSITE BEAM FOR APPLICATION TO BRIDGE SUPERSTRUCTURE

摘要

There have been many researches that deal with the wood-concrete composite system especially for the bridge superstructure. Many of the researches have been conducted to find out or improve the shear performance of the wood-concrete composites. This study was performed as the basic study of the wood-concrete composite system. The yield mode and the reference design value (Z) were derived with different anchoring length of the simple steel rebar based on the EYM (European Yield Model). Simple shear test of wood-to-wood composite was designed and performed for verification. Results shows that the yield load shows over 40% of predicted Z value which would be occurred by the differences in yield strength of tested steel rebar between the actual and designed value. Further studies including the pull-out effect of the rebar and actual yield mode investigation are now in progress.
