Worked example demonstrating the design process for a portal frame using elastic analysis methods. This document provides guidance on designing portal frames according to Eurocode standards. It discusses the importance of accounting for second order effects in portal frame analysis and design.
The publication contains explanations on different types of portal frames, considerations in the design of portal frames, functional components of portal frames, actions on portal frames, and a design example of portal frames using elastic analysis.
The examples above illustrate a portal-frame solution with just one reinforced corner (top), two reinforced corners on a single garage door (middle), and two reinforced corners flanking a double garage door.
