Abstract: A simple design formula is derived here to evaluate the fundamental frequency parameter of initially stressed (subjected to axial concentrated load at the ends) uniform beams resting on elastic ...

Abstract: A methodology is developed in this paper to evaluate the first transition foundation stiffness for columns subjected to end concentrated loads, on a Winkler foundation, where the buckling mode shape changes. The method is ...

Abstract: A Rayleigh-Ritz free vibration analysis of a simply supported beam is carried out in this note with prestress effects included through an axial compressive load and with shear deformation and rotatory inertia considered. ...

Abstract: Finite element and Rayleigh-Ritz methods have been effectively used to evaluate the thermal postbuckling behavior of columns with immovable ends in the axial direction. However, these methods do suffer from problems like ...

Abstract: In continuation of their earlier work on free vibration behavior of uniform beams in the presence of an axial load, the writers of this note evaluate the vibration characteristics of tapered beam-columns. The Rayleigh-Ritz ...

Abstract: A novel formulation is used to study the thermal postbuckling behavior of circular plates, with the edges supported to not have lateral deflection and elastically restrained against rotation. The elastic restraint is ...
