ANALYSIS OF SHINGLE JOINTS

THE DEVELOPMENT OF A MATHEMATICAL MODEL FOR SOLUTION OF SHINGLE JOINTS LOADED INTO THE INELASTIC RANGE IS DESCRIBED. AFTER SIMPLFYING ASSUMPTIONS IN ACCORANCE WITH THE AVAILABLE TEST DATA ON SHINGLE JOINTS ARE MADE, THE ANALYTICAL MODEL DEVELOPED EARLIER FOR THE BUTT JOINT IS GENERALIZED AND EXTENDED TO OBTAIN LOAD-PARTITION IN SHINGLE JOINTS LOADED BEYOND MAJOR SLIP. A COMPUTER PROGRAM WAS WRITTEN WHICH PROVIDES COMPLETE FORCE-DISPLACEMENT RELATIONSHIPS FOR BOTH THE PLATES AND THE FASTENERS FOR THE ENTIRE RANGE OF LOADING OF A BEARING TYPE JOINT. FOR MOST SHINGLE JOINTS ENCOUNTERED IN PRACTICE, THIS PROGRAM CAN BE USED TO PREDICT LOAD-PARTITION BEYOND MAJOR SLIP WHEN FASTENERS ARE IN BEARING AND SHEAR SO THAT THE TRANSFER OF LOAD BY FRICTION MAY BE IGNORED. A COMPARISON WITH THE AVAILABLE TEST DATA INDICATES AGREEMENT WITHIN 8.5% OF THE ANALYTICAL SOLUTION. /AUTHOR/
