The governing differential equations are of sixth order and the boundary conditions allow enforcement of total fixity of the end of a beam.
However, the equations have different degrees of freedom depending on whether the end of a beam sticks or slips, so we encountered difficulties in time integration.
In particular, the influence of the fastening condition at the end of a beam on the nature and on the amount of passive damping is investigated.
Based on traditional concrete column-steel beam hybrid structures, this paper ventures to propose three new hybrid joints with bolted connections by moving the plastic-hinge from the end of a beam to a weakened point, according to the idea of weakening the extension beam end-joint of a steel structure.
A pair of Langevin transducers placed at either end of a beam with either a right-angle V-shaped or Λ-shaped cross-section was used to excite and absorb ultrasonic flexural vibrations transmitted along the length of the beam from one transducer to the other.
Early balance scales--first seen in Sumeria about 9,000 years ago--consisted of two weighing pans attached to either end of a beam, which sat delicately balanced on a central pivot.

A semirigid connection is idealized as a zero-length elastoplastic element attached to either or both ends of a beam element.
All un-corroded beams failed with the development of diagonal shear crack in the shear span at both ends of a beam, the crack advancing from the support and moving towards the load point (Fig. 6).
The concrete within the gross cross section in end portions of a column from the face of the beam to a distance equal to the overall column depth, and in end portions of a beam from the face of the column to a distance equal to the overall beam depth, was modelled as partially confined.
First, the coefficient matrices for the intermediate concentrated elements, pinned support, applied force, left-end support and right-end support of a beam are derived.
The machines in those films were basic: a seat on the end of a metal beam.
