Pipe Rack Loads - 01/21/05 07:39 AM
I am making a comparison of anchor loads on a pipe rack in seismic ( load acting axially to the pipe case U i.e pure Seismic ) based on hand calculation and CAESAR output. I am new to pipe stress.
My methodology is :
Total wt.times base shear coefficient - Total Friction load = Total Anchor load and load per Anchor= Total load /nO. OF ANCHORS.
If my hand calculation method is correct, the Anchor load should be equal to zero if the base shear value ( which i have taken as 0.3g) is equal to friction coefficient ( taken as 0.3).
I have used Friction coefficient at all restraints ,all og which are vertical restraints but the CAESAR II calculated values and Hand calculation results do not match.
Kindly correct me where I am wrong.
