Hardboard-Webbed I-Beams: Effects of Long-Term Loading and Loading Environment.

Abstract

Twelve-foot and 6-foot I-beams with webs of two different hardboard materials and plywood were subjected to constant loads in three different humidity environments. After 17,000 hours of test, the performance of the hardboard-webbed I-beams appears to be at least comparable to that of I-beams with plywood webs. Results of this study will be useful to researchers, designers, and building code officials for judging the acceptability of wood-base materials in structural components such as I-beams. (Author)
