The jurisdiction that I do most of my work in is preparing to make the switch to IBC 2012 as the governing code. I am in a coastal hurricane prone region with a Vasd = 120 mph. Using the IBC 2012 charts for Risk Category II the Vult = 130 mph. I understand the differences in the codes and modified load combinations but using the new code both my MWFR and C&C design pressures are about 30% less with IBC 2012 than with IBC 2009. Has anyone else run into lower design wind pressures? I thought that even though the nomenclature within the code has changes, design values would be similar.
