Simply Supported BeamSpring-Mass Damper SystemVibration ControlProton exchange membrane fuel cells or sometimes called as polymer electrolyte membrane (PEM) fuel cells is a device for energy transformation in a changing process from one form of energy to another form of energy. It became as an ...
13. What is the primary cause of positive bending moment in a simply supported beam? Internally shear forces Externally applied loads Distributed axial loads Torsional moments Answer:B) Externally applied loads Explanation: When the beam bends concavely upward due to externally applied stresses, there...

The paper investigates the vibration response of functionally graded (FG) and viscoelastic/fractionally damped beams located on the Pasternak foundation. The vibration suppression of this simply supported FG beam subjected to a point harmonic load is studied by attaching fractionally damped absorbers in o...
Six simply supported (NPCBs) beams, five beams with openings, and one solid specimen used as a reference beam were all tested as part of the experiment. All of the beams were subjected to a monotonic midpoint load test. The configuration of the opening (quadrilateral or circular), as well...
Finally, based on the simplified model of the vehicle, bridge and TMFD, coupled differential equations of motion is derived, the same has been solved numerically using the Newmark’s linear acceleration method. The bridge is idealized as a simply supported Euler–Bernoulli beam with uniform ...
A simple elastic simply supported beam with two breathing cracks is considered for the dynamic analysis. The stiffness of the cracked beam is found out by using influence coefficients. The influence coefficients are calculated by using castigiliano's theorem and strain energy release rate (SERR). ...

In this paper, a novel method is proposed to evaluate the system reliability of a simply supported beam bridge by considering multiple failure criteria based on multivariate copulas and the analytic hierarchy process entropy weight (AHP–EW) method. The method first considers multiple failure criteria...
