Abstract
The principal aim of this paper is to present a numerical model for predicting the
natural frequencies of elastic composite beams, like bridges, with different
intermediate conditions. The prediction of natural frequencies is carried out
using the Transfer Matrix- Analog Beam Method [TMABM]. The effects of
intermediate conditions such as elastic supports and hinge have been included in
the presented model. Elastic composite beams are composed of an upper slab and
a lower beam connected at the interface by shear transmitting studs. Parametric
studies on the effects of various geometric and material parameters on the
fundamental natural frequencies of elastic composite beam are conducted. The
obtained results show that these parameters must be taken into accou
