Abstract

BOLTED END-PLATE STEEL CONNECTIONS HAVE BECOME MORE POPULAR DUE TO EASE OF FABRICATION. THIS PAPER PRESENTS A THREE DIMENSION FINITE ELEMENT MODEL (FEM), USING THE MULTI-PURPOSE SOFTWARE ABAQUS, TO STUDY THE EFFECT OF DIFFERENT GEOMETRICAL PARAMETERS ON THE ULTIMATE BEHAVIOR OF THE CONNECTION. THE PROPOSED MODEL TAKES INTO ACCOUNT MATERIAL AND GEOMETRICAL NON-LINEARITY, INITIAL IMPERFECTION, CONTACT BETWEEN ADJACENT SURFACES AND THE PRETENSION FORCE IN THE BOLTS. THE FINITE ELEMENT RESULTS ARE CALIBRATED WITH PUBLISHED EXPERIMENTAL RESULTS ''BRIEFLY REVIEWED IN THIS PAPER'' AND VERIFIED THAT THE NUMERICAL MODEL CAN SIMULATE AND ANALYZE THE OVERALL AND DETAILED BEHAVIOR OF DIFFERENT TYPES OF BOLTED END-PLATE STEEL CONNECTIONS. USING VERIFIED FEM, PARAMETRIC STUDY IS THEN CARRIED OUT TO STUDY THE ULTIMATE BEHAVIOR WITH VARIATIONS IN: BOLT DIAMETER, END-PLATE THICKNESS, LENGTH OF COLUMN STIFFENER, ANGLE OF RIB STIFFENER. THE RESULTS ARE EXAMINED WITH RESPECT TO THE FAILURE MODES, THE EVOLUTION OF THE RESISTANCE, THE INITIAL STIFFNESS AND THE ROTATION CAPACITY. FINALLY, THE ULTIMATE BEHAVIOR OF THE BOLTED END-PLATE STEEL CONNECTION IS DISCUSSED IN DETAIL, AND A RECOMMENDATION FOR THE DESIGN PURPOSE IS MADE.
