IAPMO UES EC 038
Full Name
IAPMO UES EC 038 – Evaluation Criteria for Diaphragm Strengthening Using Fiber-Reinforced Polymers
Scope
IAPMO EC 038 outlines the evaluation criteria for diaphragm strengthening using fiber reinforced polymers (FRP). This standard, developed by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES), focuses on assessing the suitability and performance of FRP systems for strengthening existing concrete diaphragms in buildings.
The scope of EC 038 includes:
- Purpose: to provide a standardized set of requirements for evaluating the suitability of FRP systems for strengthening concrete diaphragms in buildings.
- Applicability: it applies to FRP systems used to enhance the in-plane shear capacity of existing concrete diaphragms, typically in seismic retrofitting or structural rehabilitation projects.
- Performance requirements: it defines the minimum performance standards for FRP systems, including bond strength, shear strength, and durability, to ensure they can effectively reinforce the diaphragm and improve its seismic performance.
- Testing procedures: it outlines standardized testing methods to evaluate the bond and shear performance of FRP systems on concrete diaphragms, considering factors such as concrete strength, surface preparation, and FRP material properties.
- Design considerations: it provides guidance on the design and detailing of FRP strengthening systems for concrete diaphragms, including layout, anchorage, and connection details.
By adhering to IAPMO EC 038, manufacturers can ensure that their FRP systems meet the necessary standards for strengthening concrete diaphragms. This can lead to their products being listed and labeled by IAPMO UES, which helps build trust and acceptance in the market. Engineers and contractors can also refer to EC 038 for guidance on selecting and installing appropriate FRP systems for their projects.
