New Madrid

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Good afternoon,

I need to do some analysis for an industrial outfit right by New Madrid, MO. �Of course, I am familiar with the seismic history of, and the code requirements for, the area. �However, I was not quite ready for the LRFD seismic coefficient of 1.13 and the corresponding pullout forces of 500 lbs per baseplate for a moderate-size (not the heaviest) equipment. �The currently existing (not-so-old) installation at the same site does not appear to meet anything close to the criteria dictated by the IBC. �Sure enough, before 2000 IBC, it was Seismic Zone 3; after that, it became about 2-4 times worse that the former Zone 4 - or anything on the West Coast. �

Can somebody working in the NMSZ share the experience on how do they do practical structural design utilizing existing structures there? ��
