In this study, a new closed-form solution for transverse free vibration analysis of laminated composite beams (LCBs) with arbitrary number concentrated masses is developed. The LCB modeled based on the Euler–Bernoulli beam theory and are simulated considering Dirac delta function. Obtained governing equations are, then, solved semianalytically, while frequency equation mode shapes extracted two...

This article deals with the free vibration analysis and determination of the seismic parameters of a sloping-frame which consists of three members; a horizontal, a vertical, and an inclined member. The both ends of the frame are clamped, and the members are rigidly connected at joint points. The individual members of the frame are assumed to be governed by the transverse vibration theory of an ...
