BLAST LOADING OF 8-FOOT ALUMINUM BEAMS. Technical Report R-148. Type C Final Report

Technical Report ·
OSTI ID:4058634
Sixteen built-up beams fabricated from 5456-H311 and 5456-H32 aluminum alloy were tested under uniformly distributed static and blast loads. The beams had a clear span length of 8 feet 1 and 5/16 inches and an end fixity of 85%. Three beams were loaded statically to failure. The remaining beams were subjected to blast loads of smaller magnitude to determine the dynamic response. Buckling occurred after yielding in the lower flsnge and web adjacent to the supports at static and dynamic loads of 130 and 63 pounds per inch, respectively. Based on a yield load with a factor of safety of 1.65, design static and dynamic working loads of 64 and 29 pounds per inch, respectively, are recommended for the specific beams tested. A chart is included which may be used to predict the maximum deflection of a structural member in the plastic range under a longduration load once the static properties are known. (auth)
