MNSEA Monthly Meeting - January 2023
Speaker / Presentation: Strengthening with Fiber-Reinforced Polymer (FRP) with Dillon Rudrud, Simpson Strong-Tie
FRP isn’t the most common application, so the goal of this presentation is to educate attendees all on its basic premise and explain what resources are available to the engineer and how to properly apply the principles of FRP design.
- First, we will define the individual components of the composite system and delve into how each component works together in the system.
- Once the individual components have been defined, we will introduce two common products: uni/bidirectional fabrics and pre-cured laminate strips. We will explain their differences and in addition to how these products interact with and strengthen concrete.
- Next, we will go over installation methods for both fabrics and laminates. In addition to proper installation techniques, we will provide an overview of recommended quality control measures and ASTM tests that should be performed on-site.
- The last general topic we will cover the guidelines and provisions outlined in the ACI440.2R, ACI440.7R – FRP-specific guides – and ACI562 – the code for concrete repair and rehabilitation. We will go over simple design examples and explain how these apply to FRP analysis and design.
- Finally, we will summarize all of the covered topics and convey the services which Simpson Strong-Tie’s engineering department offers at all points of the project. We will provide services by way of feasibility studies, drawing details, budget estimates, and final stamped submittals.
