SKEW GIRDERS

A THEORETICAL PROCEDURE FOR THE ANALYSIS OF SKEW GIRDERS IS DEVELOPED, TAKING INTO CONSIDERATION THE EFFECT OF ELASTIC YIELDING OF SUPPORTS. VALIDITY OF THE THEORY IS TESTED BY THREE CONCRETE MODEL GIRDER CONFIGURATIONS WITH VARIATIONS IN BOTH SKEW ANGLE AND ELASTIC YIELDING OF SUPPORT. THEORY AND MODEL TESTS SHOW THAT ELASTICITY OF SUPPORT IS AN IMPORTANT FACTOR IN ESTIMATION OF BENDING, TORSIONAL MOMENTS AND SUPPORT REACTION, BUT FIELD REACTION TESTS OF FULL-SCALE BRIDGES INDICATE THAT THE AMOUNT OF SUPPORT YIELDING IS DIFFICULT TO PREDICT AND CAN BE NEGLECTED IN DESIGN. ON THE BASIS OF THE THEORETICAL AND EXPERIMENTAL RESULTS, A PRACTICAL DESIGN METHOD FOR SKEW CONCRETE GIRDERS IS SUGGESTED FOR THREE TYPICAL CASES: STANDARD (PARALLEL) SKEW, HALF-SKEW, AND TRAPEZOIDAL SKEW. /RRL/A/
