ANALYSIS OF SHINGLE JOINTS

DEVELOPMENT OF A MATHEMATICAL MODEL IS PRESENTED FOR THE SOLUTION OF SHINGLE JOINTS LOADED INTO THE INELASTIC RANGE. AFTER MAKING SIMPLIFYING ASSUMPTIONS IN ACCORDANCE WITH THE AVAILABLE TEST DATA ON SHINGLE JOINTS, 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 COMPARSION WITH THE AVAILABLE TEST DATA INDICATES AGREEMENT WITHIN 8.5% OF THE ANALYTICAL SOLUTION. /AUTHOR/
