Simple Supported Beams Beams Materials Engineering ...

A beam is a horizontal structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the beam as a result of the external loads, own weight, span and external reactions to these loads is called a bending moment.

12. VIBRATION ISOLATION

place to mount a vibrating machine is on the ground floor. Unfortunately (but fortunately for noise control consultants), this is not always possible. A typical problem is a rotating machine (such as a pump, AC compressor, blower, engine, etc) mounted on a roof, or on a floor above the ground floor. The problem is usually most apparent in the immediate vicinity of the vibration source. However ...

Stiffness in Timber Floors and Ceilings

A simple calculation showed that the principal beams were slightly undersized for the span, resulting in a liveload deflection that promoted a low frequency in the floor vibration. A failure to think laterally would have resulted in the complete lifting of the floor finish in an attempt to stiffen the principals. This would have been difficult in view of the ornate plaster ceiling below and ...
