How load is measured on Tributary Area


In this exclusive civil engineering tutorial presented by John Tingerthal, you will learn to find out the distributed load on a beam and column for a unsymmetrical deck supported with beam and plank system.

Plank and beam construction alias framing stands for a type of framing that does not contain joists rather than broadly placed beams spaced with large planks. This system is suitable for timber framed roofs.

When the beam provides support to a floor, roof, or wall which contain a pressure loading normal to the surface, the entire force on the beam is equivalent to the area of surface supported (i.e. the tributary area) times the pressure on the surface.

In this video, solution is given to the following problem:-

Find out the loads on each beam.

Find out the loads at each column support.

Where,

Live load is given as 60 psf

Dead loads are given as follow:-

Deck = 8 psf

Beam = 10 plf

Column = 100#

To get more details on this, go through the following video tutorial.
