In this article on increasing the efficiency of steel combined structures, tasks rational design, regulation and control structural parameters elements, use steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder truss elastic supports, which operates under distributed load, moment 72 times smaller than single-span beam. suggested to high-st...
In this paper, the problem of adding damping to a vibrating string is considered. Instead of using feedback control or frequency domain techniques, a wave-analysis approach proposed by von-Flotow for beams and trusses is used. This technique is based upon the premise that resonances are caused by waves reflecting off of discontinuities. By eliminating the reflections, the resonances will dissap...
