FATIGUE STRENGTH OF HYBRID PLATE GIRDERS

THE RESULTS OF 63 HYBRID GIRDERS TESTED AT THE UNIVERSITY OF TEXAS, AUSTIN ARE PRESENTED. SIX GIRDERS HAD A441 STEEL FLANGES AND THE OTHERS HAD A514 STEEL FLANGES. ALL GIRDERS HAD A36 STEEL WEBS. FORTY-THREE GIRDERS WERE TESTED IN BENDING, THREE IN SHEAR, AND SEVENTEEN IN COMBINED BENDING AND SHEAR. VARIABLES INVESTIGATED WERE WEB SLENDERNESS RATIO AND THE STRESS RANGE. BASED ON THE LIST RESULTS AND THOSE OF HOMOGENEOUS CARBON STEEL PLATE GIRDERS PREVIOUSLY INVESTIGATED, CONCLUSIONS ARE DRAWN ON WEB SLENDERNESS RATIO AND INITIATION OF FATIGUE CRACKS. /ASCE/
