Book Description
A method was developed for computing the deflection and lifetime of multiweb box beams subjected to creep under varied loads at constant temperatures. The method of analysis is based on the life-fraction rule and materials creep data obtained from constant-load and constant- temperature tensile creep tests. Calculated deflection and lifetime results are compared with corresponding test data from multiweb box beams fabricated from 2O24-T3 aluminum-alloy sheet and tested at 400 F under cyclic creep loads. An equivalent-stress concept is utilized in a portion of this study to reduce the varied-load creep problem to creep under constant stress.
