Hello,
I was wondering if anyone could help me in understanding Section 3.1.11.3 of ASCE 113 concerning deflection calculations. This section suggests using the un-factored extreme wind and un-factored extreme icing loads if the equipment is operating during extreme wind or extreme ice. Is the factor this section is speaking of the conversion factors mentioned in the sections prior (3.1.11.1 & 3.1.11.2) or the load factors? I'm inclined to think these factors are the conversion factors, which reduce the loads applied, rather than the load factors, which increase the loads applied. It seems odd to me that we would consider a reduced load for extreme conditions (i.e. not using load factors). Any help is greatly appreciated!
