PROBLEM TO BE SOLVED: To provide a concrete frame, which hardly causes brittle fracture of concrete. SOLUTION: The concrete building frame 10 is constituted by horizontally and vertically connecting a plurality of triangular structure units 60 each formed by assembling a pair of bar-like concrete diagonal members 30 and a concrete floor member 20 in a triangular shape. According to such a structure, the diagonal member bears an oblique compression stress which is born by a compression strut in a column in the prior art, and the compression stress acts on the diagonal member substantially in the axial direction without local increase in compression load, thereby the brittle fracture can be prevented.
