The Computer Analysis of Orthotropic Steel Plate Superstructures for Highway Bridges. Volume II. Program Description Type I Bridge

摘要

The volume describes a complete set of computer programs, together with the input-output format, for structural design of a highway bridge superstructure using orthotropic steel plate decks. This volume is applicable to Type I bridge, an orthotropic plate deck on twin I-shape girder. The deck span consists of closed ribs, floor beams, and plates. The programs are written specifically for IBM 1620 computer system with 60K memory locations. There are seven phases in the volume. They should be executed consecutively. Programs for Phases I through V inclusive are written in FORTRAN II while programs for Phases VI through VII are in SYMBOLIC PROGRAMMING LANGUAGE. The maximum number of lanes of the bridge considered in this volume is six, although little effort is required to increase the number of lanes. It should be noted that the secondary stresses are not considered in Type I bridge as discussed in this volume. (Author)
