Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation was to study the flexural fatigue strength of two prestressed steel I-beams which had previously been fabricated in connection with a jointly sponsored project under the auspices of the Iowa State Highway Commission. The beams were prestressed by deflecting them under the action of a concentrated load at the center of a simple span, then welding unstressed high strength steel plates to the top and bottom flanges to retain a predetermined amount of prestress. The beams were rolled sections of A36 steel and the plates were USS "T-1" steel. Each of the two test specimens were subjected to an identical repeated loading until a fatigue failure occurred. The loading was designed to produce stresses equivalent to those which would have occurred in a simulated bridge and amounted to 84 percent of a standard H-15 live load including impact. One of the beams sustained 2,469,100 repetitions of load to failure and the other sustained 2,756,100 cycles. Following the fatigue tests, an experimental study was made to determine the state of stress that had been retained in the prestressed steel beams. This information, upon which the calculated stresses of the test could be superimposed, provided a method of correlating the fatigue strength of the beams with the fatigue information available on the two steels involved.

Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Reinforced Concrete Research Council of ASCE. This report reprints a collection of studies advancing the knowledge of the effects of fatigue loading on the structural behavior of prestressed concrete flexural members. Each study represents one phase of an extensive research program conducted at Lehigh University and sponsored by the Pennsylvania Department of Transportation, the Federal Highway Administration, and the Reinforced Concrete Research Council. The four areas of study are: the effect of stress gradient on the probable fatigue life of plain concrete, as related to the compression block of prestressed concrete flexural members; the probable fatigue life of seven-wire prestressing strand under repeated loading of either constant or varied magnitude; the probable fatigue life of prestressed concrete flexural members, as limited by the fatigue failure of the prestressing strand; and the susceptibility of prestressed concrete flexural members to fatigue failure in shear. This report provides guidance to structural engineers faced with the design or analysis of prestressed concrete flexural members and to research engineers who are seeking to extend the knowledge of structural behavior as affected by repeated loading.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past 20 years, the Transport and Road Research Laboratory has carried out a co-ordinated programme of fatigue testing, including work on the fatigue performance of reinforced and pre-stressed concrete beams. The research has led to a better understanding of the fatigue behaviour of plain concrete, the various types of reinforcing bars in air and concrete, continuous welded, lapped and coupled bars, and the effects of corrosion. The work of TRRL and many other organizations is reviewed and a summary of current design rules with recommendations for assessing the fatigue life of new structures in service is given.

This book was released on 1963 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two composite, prestressed, steel beams, fabricated by slightly different methods, were fatigue tested to destruction. Stresses and deflections were measured at regular intervals, and the behavior of each beam as failure progressed was recorded. Residual stresses were then evaluated by testing segments of each beam. An attempt was made to assess the effects of the residual stresses on fatigue strength.
