Abstract: Higher strength concrete and lighter concrete have been employed for the construction of slender concrete structure. Such concrete also requires for superior structural performance and higher durability. For rational design of durable concrete structure, the structural performance of concrete must be evaluated appropriately. The purpose of the present study is to obtain the shearing behaviour of various concrete elements, and to quantify various reinforcements for shear failure of concrete member. Mechanical behaviour of FRC element is evaluated experimentally by the simple pure shearing machine. The concrete materials in the present study include high strength concrete and high performance lightweight concrete.
Every concrete specimen without fiber was brittle failure caused from a crack. Conversely, first crack in concrete specimen with fiber occurred in the centre section and some cracks occurred in various sections after max loading. The relationship between shearing stress and deformation of FRC elements were investigated, which such relations cannot be obtained in case of brittle materials. FRC elements under pure shearing stress indicated extreme more ductile performance than plain concrete. As the ultimate strength, pure shearing strength of FRC elements had almost 20 percent higher than the strength of plain concrete.
