STATISTICAL VARIABILITY AND PROBABILITY OF FAILURE OF REINFORCED CONCRETE MEMBERS

THE PROJECT DESCRIBED INVOLVED THE TESTING TO FAILURE OF A RELATIVELY LARGE NUMBER OF REINFORCED CONCRETE MEMBERS AND COMPARING THE MEASURED STATISTICAL PROPERTIES WITH THOSE CALCULATED USING STANDARD PREDICTION FORMULAE. THE OBJECT OF THE EXPERIMENTAL INVESTIGATION WAS TO PROVIDE RELIABLE STATISTICAL INFORMATION ON THE FAILURE LOADS OF THE REINFORCED CONCRETE MEMBERS. IN ORDER TO SIMULATE ACTUAL CONSTRUCTION PRACTICE, READY-MIXED CONCRETE WAS USED AND THE REINFORCING CAGES WERE MADE BY A COMMERCIAL FIRM. THREE TYPES OF REINFORCED CONCRETE MEMBERS WERE CONSIDERED: THE SIMPLE BEAM, A TWO-SPAN CONTINUOUS BEAM, AND A TIED COLUMN. LOAD TESTS WERE CARRIED OUT 28 DAYS AFTER CASTING, THE THEORETICAL STUDY WAS CONCERNED WITH THE DETERMINATION OF THE PROBABILITY OF FAILURE INHERENT IN CURRENT BUILDING CODE DESIGN EQUATIONS. THIS INVOLVED THE TESTING OF THE VALIDITY OF CURRENT PREDICTION FORMULAE. RESULTS OF THE INVESTIGATIONS ARE SUMMARIZED. /TRRL/
