IAPMO UES EC 033
Full Name
IAPMO UES EC 033 – Evaluation Criteria for Cold-Formed Steel Shear Tab Connection at the Steel- Concrete Interface of Composite and Non-Composite Members
Scope
IAPMO EC 033 outlines the evaluation criteria for cold-formed steel shear tab connections at the steel-concrete interface of composite and non-composite members. 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 these connections in construction.
The scope of EC 033 includes:
- Purpose: to establish minimum requirements for cold-formed steel shear tab connections at the steel-concrete interface of composite and non-composite members.
- Applicability: it applies to shear tab connections used to transfer shear forces between cold-formed steel members and concrete slabs or walls. These connections are commonly used in composite floor and wall systems, as well as in non-composite applications where shear transfer is required.
- Performance requirements: it defines the minimum performance standards for these connections, including shear strength, stiffness, ductility, and fatigue resistance. This ensures that the connections can withstand the design loads and provide adequate structural performance.
- Testing procedures: it outlines standardized testing methods to evaluate the performance of shear tab connections under various loading conditions, such as static, cyclic, and fatigue. This helps to verify the strength and durability of the connections.
- Design considerations: it provides guidance on the design and detailing of shear tab connections, including the selection of materials, dimensions, and connection configurations. This helps to ensure that the connections are properly designed and constructed to meet the intended performance requirements.
By adhering to IAPMO EC 033, manufacturers and designers can ensure that their cold-formed steel shear tab connections meet the necessary standards for safety and performance. This can lead to their products being listed and labeled by IAPMO UES, which helps to build trust and acceptance in the market.
