Structural Load Testing: When Calculations Aren't Enough

Structural load testing is an important tool for evaluating existing buildings and building components when traditional analysis alone cannot confidently resolve questions of strength, serviceability, or code compliance. These situations commonly arise in aging structures, adaptive reuse projects, historic buildings, and facilities with incomplete documentation or nontraditional construction. While load testing can be highly effective, determining when it is appropriate, how it should be conducted, and how results should be interpreted require careful engineering judgment. 

In this webinar, engineers John Pearson and Rich Lindenberg provide a practical overview of structural load testing for existing structures. The presentation discusses why load testing is performed; how it is addressed in building codes and material standards; and the differences between proof, ultimate, and failure testing. Through a series of real-world case studies, the presentation illustrates how load testing can be used to manage uncertainty, validate analytical assumptions, and avoid unnecessary repairs or strengthening. 

By the end of the webinar, you will be able to: 

• Identify common scenarios in which structural load testing is an effective evaluation tool and when alternative solutions may be more suitable 
• Explain the code basis and performance objectives for different types of load tests 
• Distinguish between load-controlled and displacement-controlled testing approaches 
• Describe how load testing can be integrated into broader structural assessment and risk management strategies
