COST-EFFICIENT COMPUTER ANALYSIS METHOD AND PROGRAM FOR HORIZONTALLY CURVED BOX-GIRDER BRIDGES. FINAL REPORT

A computer analysis method and two program versions are presented for the analysis of horizontally curved, torsionally stiff continuous bridges with proportions approaching those of a curved beam. Natural coordinates simplify operator input for complex curvatures. Torsional properties of single and multi-cell box girders are computed within the program. Output consists of bending moment, torque, vertical shear, vertical displacement, rotation and web shear distribution. One program listing is in FORTRAN 77 for main-frame computers and one listing is in BASIC language for use on the TRS-80 Model 4 micro-computer or for conversion to other micro-computer systems. The results of this project are expected to be useful to State Bridge Division designers for preliminary design of many bridges and final design of some.
