INTRODUCTION TO THE PROCEEDINGS OF A WORKSHOP ON SYSTEMS BUILDING FOR BRIDGES

SPECIAL REPORT 132 COMPRISES THE PROCEEDINGS OF A WORKSHOP ON SYSTEMS BUILDING FOR BRIDGES HELD IN MAY 1971. THE FIRST THREE PAPERS REVIEW THE CURRENT STATUS OF BRIDGE BUILDING, MATERIALS, AND SYSTEMS BUILDING. THE NEXT GROUP OF PAPERS CONSISTS OF SUMMARY REPORTS OF THE THREE WORKING SESSIONS AND THE FOUR CONFERENCE GROUPS. THE REPORT CONCLUDES WITH COMMENTS BY PARTICIPANTS DURING AN INFORMAL DISCUSSION AT THE FINAL SESSION. WORKSHOP PLANNING AIMED AT GETTING GOOD STATE-OF-THE-ART COVERAGE FOR CONCRETE, STEEL, AND FOUNDATIONS AS USED IN SYSTEMS BUILDING OF BRIDGES. THE COVERAGE FOR FOUNDATIONS AND STEEL IS LESS COMPLETE THAN THAT FOR CONCRETE. DISCUSSIONS OF DESIGN PHILOSOPHY WERE ALSO LESS REWARDING THAN HAD BEEN HOPED. IT WAS APPARENT FROM THE WORKSHOP THAT TECHNOLOGY FOR MANUFACTURING, TRANSPORTATION, AND ERECTION IS CURRENTLY AVAILABLE. FOUNDATIONS PRESENT A REAL PROBLEM, AND ALTHOUGH PROGRESS IS NOT IMPOSSIBLE ITS ACHIEVEMENT WILL BE SLOW AND EXTREMELY DIFFICULT. SYSTEMS BUILDING TECHNIQUES FOR PIERS, ABUTMENTS, SUPERSTRUCTURES, AND DETAILS AND APPURTENANCES ARE NOW BEING USED; FROM THE STANDPOINT OF TECHNOLOGY, CONCRETE HAS A PRICE ADVANTAGE, AT LEAST FOR THE PRESENT. THERE WAS A STRONG FEELING THAT BETTER USE CAN BE MADE OF AVAILABLE MATERIALS. THE STEEL INDUSTRY NEEDS TO BECOME MORE INNOVATIVE AND MORE COMPETITIVE WITH THE PRESTRESSED CONCRETE INDUSTRY. ALUMINUM MUST BECOME MORE COMPETITIVE IN COST. EXPERIENCE IN EUROPE INDICATES THAT WITH NEW AUTOMATED FABRICATION TECHNIQUES, STEEL, ALUMINUM, AND TIMBER CAN BE USED MORE THAN HERETOFORE. AT THE END OF THE CONFERENCE, FOUR AREAS WERE DESIGNATED IN WHICH SYSTEMS BUILDING SEEMS TO HOLD THE GREATEST PROMISE.
