Serial Information: Transactions of the American Society of Civil Engineers, 1959, Vol. 124, Issue 1, Pg. 472-490
Document Type: Journal Paper
Design procedure for simply supported steel beams making possible utilization of statically indeterminate composite action and favorable initial stress distribution to strengthen available beam sections; variation of Queen Post truss with pretensioned tie rod is studied and weight savings of over 30% demonstrated by example design; techniques based entirely on elastic considerations.
