The USGS spectral response graphs are all based off of 5% damping, however IEEE-693 (6.9) and ASCE 113 (5.6.2.1) for electrical substation design both state that a maximum damping value of 2% must be assumed for all structures.
These structures are basically inverted pendulums supporting...

Dang... and here I thought it was a simple question...
Is SAP seriously not capable of modeling a cable over a frictionless connection? Doesn't this happen pretty much all the time? Am really I the only one who has ever had this problem?
Starting to regret purchasing this senselessly complex...
I'm designing a simple guyed structure where the guy wires are strung across horizontal arms. Typically called a "Sidewalk" guy.
The guy cable starts by attaching to the top of the pole and then drapes across a frictionless pulley on the extended horizontal arm before anchoring to the ground...
