Abstract

In this study, in order to establish impact resistant design method for the roof of RC rock-shed by using reinforced concrete mixed with PVA short-fiber, impact loading tests of large-seale shear-failure type RC beam taking with/without PVA short-fiber and falling height of steel weight as variables. From this experiment, following results are obtained: 1) impact resistant capacity of large-scale shear-failure type RC beams can be improved due to mixing PVA short-fiber into concrete; and 2) evaluating input impact energy in terms of impact resistant capacity, that of the RC beam mixed with 1 % of volume ratio of PVA short fiber can be upgraded by 2.5 times than that of the RC beam mixed without short-fiber.
