Connections in Steel Structures (edX)

Students will leave this course with an in-depth knowledge of relevant limit states as well as a familiarity with the AISC360 (American Institute of Steel Construction) provisions for simple and moment connections. This course is best suited for students with an undergraduate civil engineering background including a basic steel design course and will build on these concepts.

Students will learn from a top researcher with over 20 years of experience in the field. Professor Varma focuses on teaching through exploring example problems and applications of fundamental concepts, encouraging his students to both understand the principles of composite behavior and be able to apply these concepts in realistic design scenarios.

This course is part of the Structural Design MicroMasters.

What you'll learn

- Design simple connections using standard AISC approaches

- Evaluate eccentrically loaded bolt and weld groups using elastic and ultimate strength approaches.

- Understand special provisions for moment and concentrated forces connections.

Syllabus

Week 1: Connection Design Review - Bolted Connections

Review bolted connection basics including force transfer mechanisms, bolt shear and bearing, and slip critical connections.

Week 2: Connection Design Review – Welded Connections

Review welded connection basics including types of welding, AISC360 provisions for fillet welds, and weld limit states.

Week 3: Eccentrically Loaded Bolts – Elastic Method

Introduce eccentrically loaded connections and detail the elastic design method for eccentrically loaded bolt groups.

Week 4: Eccentrically Loaded Bolts – Ultimate Strength Methods

Introduce the ultimate strength method for eccentric design and contrast it to the elastic method. Develop design tools to calculate the strength of an eccentrically loaded bolted connection.

Week 5: Eccentrically Loaded Welds – Elastic Method

Discuss applying the elastic method to weld design and develop design tools to calculate the capacity of an eccentrically loaded weld group.

Week 6: Eccentrically Loaded Welds – Ultimate Strength Method

Apply the ultimate strength method to eccentrically loaded weld design and develop a design tool to evaluate the capacity of a weld group using this method.

Week 7: Moment Connections and Concentrated Forces

Introduce moment connections and applicable limit states. Discuss designing for concentrated forces and appropriate stiffener design.
