DEFLECTION OF REINFORCED CONCRETE AND PRESTRESSED CONCRETE BRIDGES

DURCHBIEGUNG VON STAHLBETON- UND SPANNBETONBRUECKEN

THE MOST UP TO DATE INFORMATION ON THE CALCULATION OF THE DEFLECTIONS OF REINFORCED CONCRETE AND PRESTRESSED CONCRETE SUPPORTING STRUCTURES IS CONTAINED IN SPECIFICATIONS PUBLISHED BY THE EURO-INTERNATIONAL COMMITTEE ON CONCRETE (CEB). PRACTICAL APPLICATION OF THESE RECOMMENDATIONS IS HOWEVER IMPOSSIBLE BECAUSE OF THE HIGH COSTS INVOLVED. IN ORDER TO KEEP THE COSTS WITHIN REASONABLE LIMITS, TABLES AND DIAGRAMS ARE TO BE DEVELOPED WHICH ENABLE THE DATA REQUIRED TO BE ASSESSED QUICKLY. THIS SHOULD MAKE THE KNOWLEDGE IN THE SPECIFICATIONS AVAILABLE TO THE PRACTISING ENGINEER. THE WORK IS TO BE DONE IN CLOSE COOPERATION WITH THE CEB TO ENSURE THAT THE MOST RECENT RESULTS OF RESEARCH ARE TAKEN INTO ACCOUNT.
