CURVED BEAMS TEST DESIGNERS

LONG CURVED STEEL GIRDERS HAD TO BE DESIGNED FOR THE DON VALLEY DUKE-DUCHESS INTERCHANGE IN TORONTO. ROADWAY GEOMETRY DICTATED 230 FEET RADIUS CURVES. NORMALLY CONSTRUCTED OF A SERIES OF SHORT CHORDS, RESTRICTIONS IMPOSED BY THE DON RIVER AND ADJACENT RAILWAYS DEMANDED GIRDERS OF SUCH LENGTH THAT THE ECCENTRICITY RULED OUT THE USE OF STRAIGHT MEMBERS. THE COMPLEX PROBLEM OF CO-ORDINATES IN THREE DIMENSIONS WAS SOLVED WITH THE AID OF A COMPUTER. PROBLEMS INVOLVED IN THE FABRICATION OF THE GIRDERS ARE BRIEFLY DESCRIBED. /CGRA/
