The authors consider the determination of eigenforms a beam on elastic support parts. Elastic parts made rubber and laminated metal plates find wide use for seismic isolation bridges in earthquake-resistant construction. Determination structures is main stage when designing buildings resisting impacts. span structure girder considered as system uniformly distributed load, free vibrations which ...

Abstract When a glued laminated timber (GLT) beam with round hole is subjected to shear force and bending moment, the will crack fail due large tensile stress perpendicular grain stresses. If stresses acting on are known, it possible estimate fracture load. However, necessary obtain by finite element analysis, which very time consuming. In this study, easily load, we proposed formula bearing ca...

This paper is concerned with the development of new simple 4-noded locking-alleviated smart finite elements for modeling the smart composite beams. The exact solutions for the static responses of the overall smart composite beams are also derived for authenticating the new smart finite elements. The overall smart composite beam is composed of a laminated substrate conventional composite beam, a...

This paper presents a technique to predict the severity and the location of the damage in beam-like composite laminates by using modal parameters as input for an artificial neural network. A laminated cantilever beam is modelled using ANSYS 5.6© finite element software. Normal mode dynamic analyses have been performed for the first three natural modes of intact and damaged beams to find the mod...
