MBIE will issue a warning about the use of loop bar details in flange-hung double-tee precast concrete floor units, and publish an amendment to Verification Method B1/VM1.
Last updated: 3 April 2018
A warning has been issued on the use of the loop bar details (that do not comply with NZS 3101 Concrete Structures Standard) in flange-hung, double-tee precast concrete flooring units.
This warning is due to concerns about the structural performance of the detail in earthquakes.
It relates to Building Code Clause B1 Structure.
This warning is issued from 3 April 2018.
