Lutfi,
Why should I design the Interior Zones using the End Zone pressures? Is there something in IBC or ASCE that I am overlooking? These loads tend to be, in certain situations, ... do I dare say "outrageously" high? Only in comparison to my pre-IBC design days just a year-and-a-half ago.
My concern is the over-specification of hurricane ties and cost. I will always appreciate the sincere importance of safety factor, but what about the ever-popular, and often credible general contractor response that "we have been constructing buildings for over twenty years, and we never had to reinforce the way we do today"? The buildings ARE still standing! During pre-IBC, I have always designed for wind, but the loads were typically lower at that time.
Ever since IBC, snow and wind loads (at least for Wisconsin) have, by design, increased dramatically! I will always design by requirement and with utmost safety in mind.
I am just looking for your comments and recommendations.
