Are there any special considerations for connection designs?
Answer When designing moment/cantilever connections please bear in mind that both TBG300 & TBN100 have a low surface coefficient of friction meaning the interface will have a lower slip performance than a steel washer connection interface. It may also be necessary to consider the small increase in additional bending moment that will occur in the bolts due to the separation of the steelwork flanges when the thermal break connection plate is installed.
