WHY YOU & YOUR EMPLOYEES SHOULD ATTEND THIS SEMINAR
The use of Fibre Reinforced Polymer materials (FRP) is often preferred for the strengthening of existing structures over more traditional methods due to the versatility of the solution, the light-weight of the material and the unobtrusiveness of the final result. However, no New Zealand guidance currently exists on how to design these strengthening systems, and engineers typically refer to international guidelines.
The seminar will present an overview of the most commonly used design guidelines for FRP materials as externally bonded reinforcement, the American Concrete Institute ACI 440.2R-2017, with input from other international documents. The provisions from ACI 440.2R are often insufficient for real applications, especially for seismic strengthening. The seminar will provide insight on several research studies conducted in New Zealand and overseas and, where possible, design guidance.
A key element of seismic strengthening of existing structures with FRP is anchorage, given the different tensile strength between the concrete and the FRP and the risk of a larger-than-expected earthquake. Anchorage however is so far not included in any design guidelines, despite extensive research completed in the last few years. Special emphasis will be placed on determining when anchorage is required and how to design suitable FRP anchors.
THIS SEMINAR WILL COVER
- Understanding the basics of Fibre Reinforced Polymer (FRP) materials, how the technical information is presented and what data to use.
- In depth understanding of the main design guidelines (mainly ACI 440) and how to use them for design.
- Awareness of the limitations of the guidelines.
- Evidence and research-based guidance for FRP strengthening solutions that are outside the scope of the main guidelines.
- The application of externally bonded FRP systems in seismic conditions.
- Understanding the advantages of anchorage for externally bonded FRP system, when anchorage is required, and how to design FRP anchors.
- Comprehensive seminar notes
- Experienced speakers with extensive knowledge of FRP materials and their application for strengthening existing buildings
- The opportunity to network with industry peers
