CONTINUOUS GIRDERS WITH DISTRIBUTED LIVE LOAD

FOR CONTINUOUS BEAMS WITH CONSTANT CROSS-SECTION AND AN IDEALIZED MOMENT-CURVATURE RELATION, THE SHAKEDOWN VALUE OF UNIFORMLY DISTRIBUTED LOADING IS CALCULATED. THE RESULTS ARE PRESENTED AS SIMPLE FORMULAE FOR BEAMS WITH 2,3 AND 4 SPANS, WITH THE LIMITATIONS THAT ONLY BEAMS WITH SYMMETRICAL SPANS ARE CONSIDERED IN THE CASE OF BEAMS WITH 3 AND 4 SPANS. IT IS FOUND THAT THE SHAKEDOWN LOAD MAY BE 30% BELOW THE COLLAPSE LOAD WITH CERTAIN RELATIONS BETWEEN SPANLENGTHS THAT ARE WITHIN THE PRACTICAL RANGES. /AUTHOR/
