Tests of ten rigid frames, 5 ft 9 1 2 in. high, 7 ft h 7 in. wide, were made to study the effect of sustained loading for 2 years on stress distribution. Measurements were taken of strains in concrete, tension and compression steel, deflections, rotations, and changes in horizontal reactions of the two-legged frames. An evaluation of the effect of time vield on flexural members is made.
