EMBEDDED BAR BEHAVIOR IN CONCRETE UNDER COMBINED AXIAL PULLOUT AND TRANSVERSE DISPLACEMENT
This paper investigates pullout behavior of embedded deformed bars in concrete under coupled transverse shear arising at a crack of reinforced concrete. It was experimentally proven that the pullout capacity, which reaches yield of steel section at a crack under umaxial tension, does not come up with full yielding of the critical section where the axial stress gets maximum, but the ultimate limit state is reached not at the RC crack plane but inside location in which induced curvature by shear slip of crack takes place. It is concluded under higher reinforcement ratio and/or flatter planes of concrete joints, coupling of pullout and transverse shear of steel at a crack cannot be ignored in structural analysis.
The paper introducess the implemented conditions which colling recycle of flexible base on Ying-DaLine.It over all xpounds the investigation of road condlitions of original pavement,indoor trial study,determination of trial lot plan as well as completion of trial lot etc.
