Joists were attached using triple grips. After checking stability it was clear that while rigidity in the N-S direction was excellent, the E-W direction was quite wobbly (as some of you might expect). The design was augmented with bracing as indicated on the diagram and included bottom-of-post to bearer braces on the E and W sides and bearer to bearer bracing in the middle section. Nogging was also added.
E-W rigidity is now excellent with no significant movement of the deck at all after a solid kickl! The builder also attached tension straps, as can be seen in the first picture, to insure that squareness is retained. This also improved rigidity.
Steps are next, then the decking boards (Merbau)
