DETAILING FOR STANDARD PRESTRESSED CONCRETE BRIDGE BEAMS

THIS BOOKLET GIVES INFORMATION ON THE DETAILING OF REINFORCED CONCRETE BEAMS THAT ARE MADE TO A SERIES OF STANDARD SECTION SHAPES FOR BRIDGE CONSTRUCTION. ITS OBJECT IS TO GIVE METHODS WHICH AVOID DETAILS HAVING AN UNDESIRABLE EFFECT ON PRODUCTION, EFFICIENCY OR SUBSEQUENT PERFORMANCE. SEPARATE SECTIONS OF THE BOOKLET GIVE INFORMATION ON THE VARIOUS FEATURES OF BEAM CONSTRUCTION. THE FIRST DEALS WITH THE CONCRETE USED AND INCLUDES NOTES ON STRENGTH REQUIREMENTS, COMPACTION, DEFECTS INCLUDING CRACKING, AND CURING METHODS. THIS IS FOLLOWED BY THE DETAILING OF PRE-TENSIONED STEEL, INCLUDING DATA ON STRAND PATTERN DEBONDING AND DEFLECTING, AND THE EFFECT OF STIRRUP GEOMETRY, SECONDARY REINFORCEMENT IS THE SUBJECT OF THE NEXT SECTION INCLUDING NOTES ON VERTICAL STEEL AT BEAM ENDS AND STIRRUP LOCATION AND FIXING. PALLETS AND SOFFIT AND SIDE FORMWORK ARE DEALT WITH, TOGETHER WITH THE DETAILING OF SKEW; A TABLE GIVES INFORMATION ON RATIONALIZED SKEW ANGLES. THE USE OF CAMBER TO OFFSET LONG TERM DEFLECTION, THE REDUCTIONS OF BOWING AND THE EFFECT OF DEBONDING SKEW BEAMS ARE DISCUSSED. THIS IS FOLLOWED BY NOTES ON LIFTING POINTS AND EDGE BEAMS. THE BOOKLET CONCLUDES WITH NOTES ON THE SITE ERECTION PROCEDURES WHICH HAVE A BEARING ON DETAILING.
