- Rayleigh-Ritz finite element model
Date of Defense 1997-12-05 Availability restricted AbstractA displacement-based Rayleigh-Ritz finite element model is developed to simulate
the static and dynamic behavior of stiffened plates. By con1paring natural frequency,
time-history, and power density predictions with experimental results, it is shown
that the model can be used to predict the vibratory behavior of wood floor systems
constructed With either solid-sawn joists, I-Joists, or parallel-chard-trusses. Furthermore.
using the model. it is shown that appropriate structural modifications can be
used to improve the performance of wood floor systems by increasing natural frequency
and reducing peak time-history velocity. Using the techniques described. a
design example is included that indicates ho,v floor acceptability can be achieved.
