The problem raised by your correspondent, F.W. Davey, in the current issue of your journal contains a fundamental error in the analysis and his results are therefore valueless.
WHILE many advantages of pre-stressed concrete beams over the ordinary reinforced concrete beam, such as reduction of deflections, lighter construction, greater safety against cracks, and possibilities for precast work, have been recognised, there is a widespread fear among engineers that these advantages may be lost due to a considerable
loss of prestress in course of time. Uncertainty is also felt about the exact effects of pre-stressing on a normal reinforced concrete beam.
