Out-of-plane responses of a circular curved Timoshenko beam due to a moving load. (English) Zbl 1061.74027
This paper is devoted to the determination of dynamic responses of a circular curved Timoshenko beam due to a moving load using the curved beam elements. The authors show that the stiffness matrix and mass matrix for the curved beam element and straight beam element are available for Euler (classical) beams, rotary curved beams and Timoshenko curved beams. In addition to typical circular curved beams, the authors also study a hybrid curved beam composed of one curved-beam segment and two identical straight-beam segments subjected to a moving load.
