The viscoelastic simple beam is taken as the mechanical model of flexible foundation with beam-wise.
In vitro pre-stressed reinforces the Guilin some workshop simple beam
Today most simple beam bridges are strengthened by a truss, which is based on the triangle.
Under the action of all these loads, we can determine the angles of rotation at the ends of each simple beam.
And numerical example is adopted to explain the influence of external prestress to the vibration frequency and modality for simple beam.
This paper reports the test results of 12 beam specimens including 8 SCC simple beams and 2 vibrated concrete simple beams and 2 SCC continuous beams under static loading after long-term actions.
Based on the simple beam theory, it analyzes the vibrancy character of straight-leg flexure structure, and derives the practical formula of this structure to calculate the resonance frequency.
The purline is often designed as a simple beam, and only it′s strength needs to be calculated, if the roof panel can prevent it′s lateral buckling and torsion.
