Drop-weight tests and static loading tests of RC frames made of polypropylene fiber-reinforced concrete are conducted to observe shock resistance performance and residual ductility. Experimental variables are fiber content and mass of the drop weight. In the impact test, the maximum drifts of the specimens are proportional to the mass of the drop weight although several collisions occur due to rebounding and the maximum acceleration is not always increased as the mass increases. In a static loading test, the initial stiffness is improved and crack lengths in the hinge areas of the columns are reduced by mixing the polypropylene fibers.
