Abstract :
The free vibration characteristics, such as fundamental frequency and mode shape of stiffened plates employing standard
finite element analysis, are investigated in this paper. The parametric study is presented for free vibration characteristics of
stiffened plates with various parameters, such as type, orientation and number of stiffeners, boundary conditions and aspect
ratio of plates and stiffener depth to plate thickness ratio. Typical mode shapes are also presented for clamped square eccentrically stiffened plates. Finally, design charts with non-dimensional parameters are proposed to determine the fundamental
frequency of commonly adopted clamped stiffened plates in construction. These charts will be very much useful for designers
for obtaining the fundamental frequencies of the stiffened plates of different dimensions without doing much complicated
analysis or using standard computer codes.
