Abstract:
Presents the results of tests on end-supported, re-inforced concrete slabs. 3 x I2 in. cross section, which were subjected to sustained loads for 5 years. The variables included three concrete slumps, two water-cement ratios, three span curing methods. lengths, and two changes Total and plastic flow deflections, in the concrete compressive strains, and changes in the steel tensile strains were obtained. The importance of the plastic flow problem in thin reinforced concrete slabs is forcibly emphasized by the large increases in deflections and strains that were obtained over 5 years.
