STRUCTURAL DESIGN BRINGS WEST GATE BRIDGE FAILURE

THIS SUMMARY OF AN AUSTRALIAN ROYAL COMMISSION REPORT ON THE WEST GATE BRIDGE COLLAPSE IN MELBOURNE (OCTOBER 15,1970) INDICATES THAT THE CONSULTANT ENGINEERS "FAILED ALTOGETHER TO GIVE A PROPER AND CAREFUL REGARD TO THE PROCESS OF STRUCTURAL DESIGN." THE BRIDGE WAS DESIGNED AS A CONTINUOUS BOX GIRDER BRIDGE WITH THREE CENTRAL SPANS STAYED BY CABLES. POOR CAMBER CONTROL HAMPERED ERECTION OF SIDE SPANS. JACKING AT SOME DIAPHRAGMS WAS EMPLOYED TO ELIMINATE LOCAL CAMBER VARIATIONS. WHEN BUCKLING DEVELOPED, BOLTS WERE REMOVED TO FLATTEN THE BUCKLE. THE REPETION OF THIS PROCEDURE LED TO COLLAPSE OF THE WHOLE SPAN. /CE-ASCE/
