Abstract:
Two 0.38 scale model roof girders were tested to develop an unusual type of precast concrete building frame. The roof girder selected departs from customary practice primarily by its slender and graceful T cross section, by its high strength longitudinal tension reinforcement, and by its inclined stirrup reinforcement. Structural design was based on the ultimate strength design procedure given in the appendix of the 1956 ACI Building Code, with some departures justified by the model girder test results . Twenty 58-h girders were later manufactured for two laboratory buildings.
