it "feels good".
Does anyone have evidence which would allow me to not use stucco or GWB as
SWs and still feel like I've tried to accommodate a customer's request?

V (949) 248-8588 * F(949) 209-2509The reality is that wallboard is stronger than stucco and plywood is stronger than wallboard; hence, it will take more energy//a more forceful earthquake to cause catastrophic failure. This is a double edged sword because the size of the survivable voids (hence number of survivors) is inversely proportionate to the weight of the structural members.During catastrophic collapse more people survive in reinforced stucco structures.As a specific example of one of many: none of the indigenous stucco-like structures during the Gujarat Earthquake collapsed; whereas, many thousands of modern structures did.Response:Expecting ridicule from FEMA -type intellectuals who have expressed their intellectual capabilities in the past with such notables as their condemnation and ridicule of the FIFA...in other words ..their chat room level assaults on the entire world..I made a comment solely because I expect there are some people out there who aren't hillbillies who actually care about sincere things.I thought that I would endure the assault because somebody out there would get the survival part of the info..escape from the dogma and start to think.doug copp

Was this a typo? did you mean to say that GWB is stronger than stucco?
Based on my experience.......stucco is much stronger than GWB; hence the code values of each.
