Dynamical Analysis of the Multispan Beams with Method of Multiple Scales

Yıl 2017, Sayı: Özel Sayı - Special Issue, 26 - 29, 31.12.2017

Multi-span beams are statically indeterminate
structures in general. They have many applications in civil engineering,
mechanism, navigation engineering and so on. For example, multi-span bridges
have been widely used in highway and railway. It is of great importance to
study the dynamic characteristic of the multi-span beams for engineering design
and scientific research. Many engineers and scientists have contributed to the
solution of the problem with their innovations, and still the subject draws
considerable attention from researchers by now. In this study, we investigate primary
resonance case of multi-span beam subject to axial load. Firstly, the mathematical
model of the problem is derived by using extended Hamilton principle. This
model has geometric nonlinearity. Here, two system of partial differential
equations are obtained for axial direction and transverse direction. The
numbers of equations and boundary conditions depends on span number. After
coupling equations in transverse and axial directions, the system of nonlinear
integro-differential equations are obtained and solved using the method of
multiple time scales.
