I am performing some volunteer structural design for a small church that will be constructed in Haiti. Does anyone know how to obtain wind and seismic data for Haiti?
Google "wind speed Caribbean" and it will pull up several pertinent documents for that part of it.
I don't know if there are any official design criteria or engineering practice restrictions.
They have a lot of experience on these sorts of projects and can probably answer a lot of questions you'll have (potentially including whether any more specific design documents are currently in place).
They don't have any wind speeds for Haiti, but the United States DoD structural engineering code (UFC 3-301-01) does list the following seismic data for Haiti:
Port-au-prince - Ss = 1.89, S1 = 0.79
Cap-Haitien - Ss = 1.50, S1 = 0.60
It isn't exactly Haiti, but Puerto Rico is at least in the same vicinity, and the ASCE 7-10 code gives wind speeds for Puerto Rico. You might begin there for some numbers to use as a starting basis.
