Abstract

This research focuses on finding a method for creating cost effective and innovative steel bridges in Colorado. The design method that was discovered to create this cost efficiency was designing the beams as simply supported for non-composite dead loads, beam weight and wet concrete, and then making the beams continuous at the pier for composite dead loads and live loads. This method eliminates the need for an expensive field splice and simplifies design details at the interior support, creating cost savings. During the research, a software package was created at Colorado State University that takes user inputted data, such as span lengths, out to out width, number of girders, and overhang along with various other inputs and outputs the lightest wide flange shape that will satisfy the loading. The girders were designed using appropriate provisions from the AASHTO LRFD Bridge Design Specifications 4th edition 2007.
