Date of Defense 1998-02-09 Availability unrestricted AbstractThree aspects in determining the first natural frequency of
steel joist supported floors were studied. The aspects are:
1) determining which finite element model best predict the behavior
of joist-slab tee-beams, 2) investigating the ability of
proposed equations to calculate the effective moment of
inertia of joist-slab tee-beams, and 3) developing a
finite element model to predict the first natural frequency
of steel joist supported floors.
Several finite element models were tested to determine which
one best predicted the experimental results of six
joist-slab setups. The model which best predicted the
experimental results was used.
Next, a study was done to determine the ability of a
proposed equation to predict the effective moment of
inertia of joist-slab tee-beams. The study modeled and
analyzed 130 joist-slab configurations and compared the
results to those calculated using the proposed equations.
Finally, a finite element modeling technique was developed
to predict the first natural frequency of steel joist
supported floors. Seven in-situ floors were experimentally
tested, and those results were compared to the predicted
values given by the models.
