Structural engineers today overwhelmingly use computerized methods to complete analysis and design tasks. These tools have great power, but also carry great risk of error or misinterpretation of results if the user has not mastered the fundamental structural concepts.

While complex problems are hard to solve by hand, engineers have long employed approximate analytical methods to estimate internal forces and deflections in structures subjected to well defined load patterns. These classical methods, while approximate, provide key insight into structural behavior that can be used to check and validate more sophisticated models.

The goal of this SE University session is to review three such methods: the principle of virtual work, the portal frame method, and the cantilever method.


Learning Objectives:

After participating in this session, the learner will be able to:

  • Understand conservation of energy and the principle of virtual work as it applies to truss and frame structures.
  • Understand the portal frame method and how it can be used to estimate approximate forces in a building frame structure.
  • Understand the cantilever method, how it differs from the portal frame method, and how it can be used to approximate forces in a building frame structure.

Handouts and registration emails for this session will be sent to SE University companies on Friday, March 9th.
