Abstract:

A METHOD IS PROPOSED FOR THE SOLUTION OF THE INELASTIC LATERAL BUCKLING PROBLEM OF AS-ROLLED WIDE-FLANGE BEAMS SUBJECTED TO EQUAL END MOMENTS. THE METHOD IS BASED ON THE DETERMINATION OF THE REDUCTION IN THE LATERAL AND THE TORSIONAL STIFFNESSES DUE TO YIELDING. THE EFFECT OF INITIAL RESIDUAL STRESSES IS INCLUDED IN THE CALCULATIONS. AN EXACT ANALYTICAL PROCEDURE IS WORKED OUT FOR SEVERAL EXAMPLES AT FIRST, AND THEN A SIMPLIFIED FORMULA IS PROPOSED WHICH REDUCES THE COMPUTATIONAL WORK CONSIDERABLY. CURRENTLY USED EMPIRICAL DESIGN PROCEDURES ARE CHECKED AGAINST THE RESULTS, AND A POSSIBLE MODIFICATION OF ONE OF THEM IS DISCUSSED
