DESIGN OPTIMIZATION OF PRESTRESSED CONCRETE SPANS FOR HIGH SPEED GROUND TRANSPORTATION

THE PROBLEM OF DESIGNING STIFF, LIGHTWEIGHT, AND LEAST EXPENSIVE ELEVATED SPANS TO SUPPORT GROUND VEHICLES IS INVESTIGATED. A COMPUTER PROGRAM USING THE DIRECT SEARCH METHOD WAS DEVELOPED TO CALCULATE OPTIMUM GEOMETRIC CONFIGURATIONS OF PRESTRESSED CONCRETE GIRDERS WITH NONLINEAR CONSTRAINT CONDITIONS INVOLVING STRESSES AND DEFLECTION; WITH SPECIFIED INPUTS ON LOADING, UNIT COSTS AND OVERALL SIZE, AND WITH CHECKS ON BUCKLING, SHEAR AND ULTIMATE SECTION STRENGTH. PARAMETERS ALLOW FOR CHOICES BETWEEN STIFF, EXPENSIVE CONFIGURATIONS OR FLEXIBLE, LESS EXPENSIVE DESIGNS. SEVERAL NUMERICAL RESULTS FOR SIMPLE SPANS ARE INCLUDED. /AUTHOR/
