Design of Plate Girders

CE 59700

Credit Hours:

1

Instructor:

Amit Varma

Learning Objectives:

After completing this course, you will be able to:

  • Understand basic buckling theory including beam and plate buckling behavior.
  • Proportion plate girders appropriately for strength and stiffness requirements.
  • Evaluate the flexural capacity of I-shaped plate girders regardless of component slenderness.
  • Describe the different shear force transfer mechanisms in plate girders including the shear strength of webs with and without tension field action and effects of transverse stiffeners.
  • Evaluate the shear capacity of an I-shapes plate girder and design transverse stiffeners as appropriate.

Description:

This course will cover fundamental concepts and applications of plate girders in the design of steel buildings and bridges. At the end of the course, the student will have an in-depth knowledge of relevant limit states / failure mode in steel components and structures, and a familiarity with the applicable topics in the AISC Specification and their basis in research / testing. The students will have some experience in solving design examples and looking at applications of the fundamental concepts learned in the course.

Homework:

Four homework assignments will be assigned throughout the course. These assignments include 1-2 problems for students to work out. Homework assignments are expected to be turn in to Gradescope in a pdf format. Homework assignments should be neat and easy to read. We recommend using Mathcad or a similar program. 60% of grade

Quizzes:

Quizzes cover the materials presented in that week's videos. Quizzes are multiple choice/true false and focus on assessing student’s knowledge after watching the videos. 15% of grade

Final Exam:

The final exam is cumulative and consists of long answer problems. 25% of grade
