A response spectrum analysis can be used in seismic design of structures. My question is if the structure is built with thin gage cold formed panels and members would the analysis be accurate, assuming that non-linear behavior would be present due to large deflection? Thanks

The flange will be made of A-105 forged material.

Not having access to the 2003 B16.5, can someone tell me what the allowable pressure rating is for a 300 pound flange at a temperature of 300F? Thanks

I know that there are several standards for acceptance levels of vibration for equipment rigidly supported. However,if a piece of equipment is supported by spring isolators, are there any acceptance levels on record. I would think that the equipment itself would have higher amplitudes of...

Has anyone had any experience with the ME Scope software program? Specifically, Modal Identification capabilities? We are interested in comments from users of the equipment rather than the distributor's advertising. I would think that numerous points must be instrumented in order to accurately...

Is there a procedure for evaluating the capacity of a cold formed steel channel with a pressure loading perpendicular to the web?

Is anyone familiar with software that can do non linear analysis of thin plated steel structures?

Is anyone familiar with structural software that can do non linear analysis of thin plate structures?

International Building Code, 2006 Edition Section 6.5.15.1 states that the force on rooftop structures with an area less than 0.1*Bh should be increased by a factor of 1.9 if located on a building less than 60' tall. Seems to me that if you were to plot the force on such a structure from 0 to...

Has anyone heard of being able to do a "Bump Test" to determine natural frequencies with the equipment running? Is this possible?
