STUDY OF CHECKING AND DELAMINATION IN GLULAM BRIDGE MEMBERS

THE EXTENT, CAUSE AND EFFECT OF DELAMINATION IN GLUED LAMINATED TIMBER BRIDGE MEMBERS WAS STUDIED. THE PAPER PRESENTS THE RESULTS OF A FIELD SURVEY OF 57 BRIDGES WITH GLUED LAMINATED TIMBER LOCATED IN THE PROVINCES OF ONTARIO, MANITOBA, SASKATCHEWAN, ALBERTA AND BRITISH COLUMBIA AND IN THE STATES OF WASHINGTON, OREGON, IDAHO, MONTANA AND MINNESOTA. THE INSPECTIONS INDICATED THAT VERY LITTLE DELAMINATION OCCURS IN PROPERLY TREATED GLULAM BRIDGE MEMBERS AND THAT, WITH ONE EXCEPTION, WHERE DELAMINATION DOES EXIST, IT IS NOT SERIOUS. THE PAPER ALSO CONCLUDES THAT THERE IS SOME EVIDENCE THAT THE MOST EFFECTIVE PRESERVATIVE FOR STRUCTURAL TIMBER IS 100 PERCENT CREOSOTE WITH A RETENTION OF 8 POUNDS PER CUBIC FOOT. /CGRA/
