Abstract

Offers guidance on preventing serviceability failure in ply-web roof beams and will be of interest to designers. It considers creep and other important factors. Procedures which have been commonly used in the design of ply-web beams have generally proved adequate for strength requirements, but experience has shown that additional dead and imposed loads (such as repair material and ponding caused either by inadequate drainage systems or sometimes by creep of these beams) have created excessive deflections or even failure as a result of insufficient strength. The majority of failures of ply-web beams, however, has been caused by inadequate serviceability.
