REINFORCED CONCRETE STRUCTURE HAVING MULTIPLE CYLINDER TYPE STEEL FIBER

摘要

PURPOSE: A reinforced concrete structure having a multi-cylinder type steel fiber is provided to induce ductile breaking due to continuous extension of a steel fiber by shortening the steel fiber into the length of a segment piece upon destruction of concrete members. CONSTITUTION: A reinforced concrete structure having a multi-cylinder type steel fiber comprises the following steps: arranging a plurality of steel fiber segment pieces which are shaped into cylinders in the longitudinal direction; attaching each fragment piece by an aqueous adhesive for integrally composing a steel fiber combination body(1); pouring concrete into a mold(10) which holds a plurality of steel fiber combination bodies side by side; and burying the steel fiber combination bodies of which segment pieces are separated from each other by the aqueous adhesive in the concrete.
