A Computer Method to Evaluate the Vibration Response of Stiffened Floor Systems to Impact LoadDonahue, Michael E. 01 January 1982 (has links) (PDF)
Composite construction of floor systems with steel joist or I-beam stiffeners supporting a concrete slab have a tendency to sustain perceptible vibration due to small impacts. An engineering design aid, utilizing a small micro-computer and a BASIC computer program, was developed to analyze rectangular floor systems for susceptibility to sustain vibrations perceptible to humans. The analytical method for the normal modes of vibration using the Rayleigh-Ritz method and the superposition of the normal mode response is derived. A vibration index is calculated to qualitatively rate the floor. The computer method was validated using published data for an I-beam supported concrete slab and a design application for a steel-joist supported floor is demonstrated using a representative human induced impact load.
