Decoding Eurocode

Best in class solutions with International ETA approvals

On 1st April 2015, Eurocode design standard has replaced British Standards as Singapore’s prescribed building codes for structural design. (BCA_Newsroom). This also means that there is now a specific set of codes that also addresses the design method post-installed rebar and anchors. 

In EC2 Clause, it states that the design methods for post-installed rebar connections must follow EC2/Technical Report 023. And for post-installed anchors, the design must follow ETAG 001 Annex C . Thus, the design methods for the two applications are completely different:

Structural Rebar connections - EC2 / TR 023

Structural Rebar connections and extensions can be safely designed like cast-in connections utilizing the design provisions provided within Eurocode 2 and EOTA TR023
