This will amount to twice as much load on the exterior walls compared to a building with a center wall. Read meyerhof s bearing capacity theory and formulas here. Floor joist span use this table to determine the maximum lengths of floor joists based on species of lumber joist spacing and joist size. Live load psf dead load psf exterior exposure.

The dead load on a floor is determined by the materials used in the floor s construction. The top column labled span carried by beam determines the span supported by your beam. For example if building is 24 x 24 and has trusses and the load on the roof will be for 30 lb snow load and a ceiling with no storage will total out like this. Length of beam is the total including all spans of the beam in mm or ft.

Live load psf dead load psf span calculator for wood joists and rafters available for the iphone. The column on the left of each chart labeled beam span represents the beam length with bearing required for your project. If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot. Multiply the maximum load per square metre by the total area of the floor.

The properties of the beam and section are specified by typing directly into the input fields. Young s modulus is set to a default value of 200 000 mpa or 29000 ksi for structural steel but can be edited by the user.
