TORSIONAL PROPERTIES OF COMPOSITE STEEL BRIDGE MEMBERS. THE DESIGN OF CURVED VIADUCTS. PROGRESS REPORT

THE ANALYSIS OF CURVED COMPOSITE HIGHWAY BRIDGES REQUIRES THE TORSIONAL PROPERTIES OF COMPOSITE GIRDERS. THE THIN WALLED THEORY OF VLASOV WAS APPLIED TO COMPOSITE BEAMS TO DERIVE A SERIES OF EQUATIONS UTILIZED IN EVALUATING THE TORSIONAL PROPERTIES OF TYPICAL COMPOSITE HIGHWAY GIRDERS. A SERIES OF TABLES ARE PRESENTED, LISTING ALL PERTINENT PROPERTIES. EXAMINATION OF THE TRENDS BETWEEN THE BENDING AND TORSIONAL PARAMETERS PROVIDED A SERIES OF EQUATIONS IN WHICH WARPING STRESS IS SET EQUAL THE PRODUCTS OF BIMOMENT, BENDING STRESS DIVIDED BY BENDING MOMENT, AND A CONSTANT DETERMINED BY A PLOT OF THE DATA. THE MAXIMUM BIOMENT VALUES WEREE DETERMINED FOR VARIOUS TORSIONAL LOADINGS. FOR ALL TORSIONAL PROPERTIES IT WAS ASSUMED THAT THE SECTION IS THIN-WALLED AND THAT THE WARPING SHEARING STRESS DEFORMATIONS CAN BE NEGLECTED. /AUTHOR/
