摘要：

The influence of various effects on mode localization in multispan beams is studied. The finite element method is used to study localization as a function of Timoshenko beam effects; beam end conditions; span length, Mass, and stiffness imperfection; viscous damping; axial force; transverse support and rotational coupling stiffness; and modeling resolution. Three configurations are studied, starting with two separate 2-span models and culminating in a 10-span configuration that resembles lattice-type large space structures. The results show that, in addition to the ratio of imperfection to coupling stiffness, transverse support stiffness and Timoshenko beam effects are also parameters that influence mode localization in structures with repeated segments.
