Title                   Introduction to Bridge Design
Lecturer            Ho-Kyung Kim
Credit                3-2-2
   
  Objective

This course teaches basic concept and procedure of bridge design. Based on the fundamental theory acquired from the pre-requisite structural analysis subjects such as mechanics of materials, structural analysis 1 & 2, this course starts from the definition of design method and design loads. The former parts are closely related to design subjects such as design of steel structures and/or design of concrete structures. Reflecting current trend of changing to Load Resistance Factor Design for steel structures, this course basically follows the LRFD method. However, for better understanding of current LFD and ASD methods adopted in KBDC, comparative examples with different design methods are also provided. At the last part of the course, all students will be encouraged to provide design solutions for a simple bridge as a term project. This will be useful to utilize all knowledge acquired in the class and promote mutual cooperation as a member of a team.

The main goals of the course are:

1) Understand design loads and combinations for highway bridge

2) Understand design philosophies and methods (ASD, LFD, LRFD)

3) Develop ability to use computer-assisted design software for bridges

4) Design a slab-on-stringer bridge as a teamwork

5) Develop ability to present
