Abstract
This study shows mechanical properties of Channel-Shaped precast PC slabs (CPC slabs) by experiments and analysis. It clearly indicates that CPC slabs have a large load carrying capacity and high durability against the traffic load through a series of systematic experiments, static and fatigue tests. On the other side, bending moment distribution of CPC slabs using wheel live loads is different from ordinary flat RC slab, due to its channel shape. Therefore, we cannot use the bending moment calculation formulae of slab design using live wheel load that defined in the Japanese specifications for high way bridge. So, FEM analysis for CPC slab was carried out to provide the original bending moment calculation formula. And the design method of CPC slabs is shown in this paper.
