Learning Objective:
By the end of this course, students will be able to analyze and design horizontally curved and skewed steel girder bridges using LRFD principles and methods consistent with current engineering practice. They will demonstrate the ability to select and apply appropriate analysis techniques to design curved steel I-girder and tub girder systems considering. Students will also integrate fabrication and construction considerations into their designs and apply finite element tools to solve practical bridge engineering problems.
Description:
This course emphasizes the practical analysis and design of horizontally curved and skewed steel girder bridges using Loud and Resistance Factor Design (LRFD), reflecting methods and standards used in current engineering practice. Students develp an applied understanding of steel bridge behavior and learn ot select appropriate analysis approaches, including approximate, two-dimensional, and three-dimensional methods commondly used in real-world design and evaluation projects. The course focuses on the deisign of curved steel I-girder and tub-girder systems, including stability bracing requirements and considerations regarding fatigue, redundancy and detailing considerations. Fabrication and construction issues unique to curved steel bridges are integrated throughout the course to reinforce realistic design assumptions. Students gain hands-on experience with finite element software used by practicing bridge engineers. The course prepares students for immediate contribution in bridge engineering practice.
