Double fixing capacity for veranda beams attached to posts as required in NZS 3604:2011 Timber-framed buildings Table 10.8 is as follows:
- A doubling of the fixing capacity for veranda beams to posts (because the gravity and uplift load carried is greater) is required for:
̵ posts that support a veranda beam joint
̵ the middle post(s) where a veranda beam spans over three or more posts.
Check the manufacturer’s rating of T brackets to ensure they meet the required capacity. Not all brackets can provide sufficient capacity.
