FYI design wind speeds are:
Serviceability limit state 39 m/s
Permissible stress method 50 m/s
Ultimate limit state 61 m/s
With global warming in mind it is becoming common to design for the next
higher wind class which would be 47, 60 and 74 m/s respectively.
So, it's not unreasonable to be concerned about the integrity of the
wall (as it never would be), but the proposed solution is faulty. I
need to convince this engineer of that without making my clients the
guinea pigs. Bruce et al's book arrived a couple of days ago. I will
meet with the engineer again next week armed with all the information
and some good advice, thanks everyone.
