Checking vibration on steel framing for a mezzanine, I got 2 similar answers by following example 4.4 of AISC Design Guide 11 (Designing for Floor Vibrations) and the Floor Framing software from the www.AISC.org/steeltools downloadable software. While those answers were similar, the analysis provided by FloorVibe via Ram Structural System indicated members being increased about 60% (conservatively). Has anyone else encountered such a discrepancy?
