ABSTRACT:
A precast concrete portal frame system includes two column sections and a rafter section, each of which are pre-cast off-site, each column section extending integrally toward a plane of symmetry of the portal frame to an uppermost articulated surface of each of the column sections which meet lowermost articulated surfaces of the rafter section, defining respectively opposing planes in complemental keyed relationship, the opposing planes also defining, in longitudinal cross-section, mating L-shaped surfaces, the inclined planes of the column and rafter sections provided with transverse bolting holes to provide a bolted connection between the rafter and column sections of the system. The upper part of each column section is enlarged to provide resistance to high bending moments.
