REINFORCED CONCRETE STRUCTURE

PURPOSE:To improve bearing force without increasing the arranging quantity of bars. CONSTITUTION:In a reinforced concrete structure having reinforced concrete columns 1 and a reinforced concrete beam 10 adapting an X-shaped arrangement structure which is erected between the reinforced concrete columns 1, an X- shaped beam main reinforcement 13 consisting of at least two beam main reinforcements 11, 12 horizontally extended while obliquely crossing each other in the plane view, both end parts of which are mutually bent inward with their intersection as a supporting point, and situated within the same perpendicular plane, is arranged in the reinforced concrete beam 1. Plural sets of the X-shaped beam main reinforcements are set in parallel to each other with a space to mutually form parallel main reinforcements in the plane view, and both end parts of the main reinforcement are extended to the bar arrangement internal parts of the reinforced concrete columns 1.
