• What is the problem of over vibration of fresh concrete?

    This serves to push down and subject the fresh concrete to confinement within the zone of vibrating action. Over vibration should normally be avoided during the compaction of concrete. If the concrete mix is designed with low workability, over vibration simply consumes extra power of the vibration, resulting in the wastage of energy.

  • Deflection Limit State B G Structural Engineering

    Any nonstructural partition under the beam must be able to accommodate this deflection. However, if it cannot, then the amount of live load deflection that can be accommodated becomes the new deflection criteria for this beam. Vibrations. Certain vibrations have been found to be objectionable in most occupancy classifications.

  • Resonance Its Causes and Importance. What is Resonance?

    When the object is made to approach or work in its natural frequency, say for example if the motor casing has a first natural frequency of 25 Hz and the motor is to run at 1500 rpm ( 25 Hz) the casing will start to vibrate in a very excited manner, with no control on the amplitude of vibration.

    The study of free inplane vibration of curved beams, using different beam theories, is more challenging than that of straight beams, since the structural deformations in curved beams depend not only on the rotation and radial displacements, but also on the coupled tangential displacement caused by the curvature of structures.
