THE EFFECTS OF INELASTIC ACTION ON THE RESISTANCE TO VARIOUS TYPES OF LOADS OF DUCTILE MEMBERS MADE FROM VARIOUS CLASSES OF METALS PART II. INELASTIC BEHAVIOR OF ALUMINUM ALLOY I-BEAMS WITH RECTANGULAR WEB SECTION CUTOUTS

摘要

This report contains an exploratory investigation of the plastic bending of aluminum alloy I-beams with rectangular web section cutouts. The mechanism method of analysis employing the upper bound theorem vas employed in predicting the ultimate loads of the various beams. the experimental results are in good agreement with the predicted ultimatenloads.
