Abstract : The accumulation of experience in the studies of prestressed beams of considerable age has appreciable importance for estimating the behavior of such designs over a period of time. This is particularly important for the actual prestressed beams in the roofs of industrial buildings, which are used in our country in a large volume and exist under varying operational conditions. Discussed are the results obtained from testing the prestressed--pitched beam in the roofing of industrial buildings with a span of 18 m (the beam is placed in the roofing with a spacing of 6 m), having been located in an open area for more than three years (1,251 days).
