PROBLEM TO BE SOLVED: To simplify construction, improve strengths and reduce costs while partially employing ultra-high strength fiber-reinforced concrete precast blocks, in a column and beam joint of reinforced concrete column and a steel beam. SOLUTION: In the joint structure of a reinforced concrete column 2 and a steel beam 3, a precast block 11 employing an ultra-high strength fiber-reinforced concrete is arranged at a position in contact with the steel beam 3. Employment of an ultra-high strength fiber-reinforced concrete satisfactory in deformation capability at the column and beam joint 1 provides strengths to withstand against stress concentration on the joint, thereby eliminating development of cracks to prevent local destruction. Furthermore, reinforcing bars may be reduced or eliminated. The joint structure employs precast blocks, simplifying construction. COPYRIGHT: (C)2011,JPO&INPIT
