Structural System Check:Around 20 PSF added per AHUFloor Deck: Ok from manufacturer cut sheetsBeams: Lateral-torsional failure directly under AHU
Redesign: Put stiffener plates at midpoints
The Eberly Campus Community Center Structural System Check:Girder: Lateral-torsional failure
Redesign: Stiffener Plate at the midpointSteel Pipe Columns: Ok from LRFD Steel ManualMasonry Bearing Walls: Ok from the
Masonry Designer’s Guide

Acoustics Check:Auditorium reverberation times: AcceptableIncrease in relative humidity:
Decrease the reverb. times of lower frequencies
Increase the reverb. times of higher frequencies
