What is psf live load?

What is psf live load?

U.S. building codes specify a uniform live load of 40 pounds per square foot (psf) for most residential floor designs. This load is intended to account for the large number of loads that can occur in a residence. In reality, these loads do not typically take the form of uniform loads.

What is the formula for live load?

The dead and live loads calculation as per IS:456-2000 is as follows. LIVE LOAD =(factored load ×l×l)/8 if it is simply supported.

What is 50 psf live load?

IBC Section 1607 specifies the prescribed minimum live loads based upon occupancy. For an office building, the minimum uniform live load is 50 psf over the entire floor area plus a concentrated load check of 2000 pounds over any 2′-6” x 2′-6” square space. This load should also be specified by the Building Designer.

How is psf load calculated?

Divide force by area to calculate the pressure exerted. Continuing with the example, divide the elephant’s 5,940 lbs by 3.14 square feet to calculate the pressure of 1,891 pounds per square foot. Divide the little girl’s 55 lbs by 0.0009 to calculate her pressure of 61,111 pounds per square foot.

How do you calculate live deck load?

Therefore, a deck of 120 square feet multiplied by 50 shows that your deck can hold 6000 pounds, including the structure. Dividing by 5 will allow you to determine that 4500 lbs is the max live load your deck can hold.

What is 10 psf Deadload?

Generally, the customary floor dead load is 10-12 PSF (pounds per square foot) for floors, 12-15 PSF for roof rafters and 20 PSF for roof trusses. However, these may increase when a heavy finish material, such as brick veneer walls or tile floors/roofs, is specified.

What is a concentrated live load?

Live loads, L, are a result of the occupancy of a structure. Certain occupancies, such as office space, have the potential for a larger concentrated load (such as a large copy machine) being located in a space.

What is concentrated load?

A concentrated load is a force applied at a single point on a beam or structure. It can be uniformly distributed, wherein the amount of force is the same throughout the area to which it is applied; or non-uniform, meaning it is not evenly spread out.

How do you convert PSF to pounds?

Divide the number of pounds the square feet will be subjected to by the number of square feet. For example, if you are putting 24 pounds on the 48 square foot platform, you would divide 24 by 48 and find that you have 0.5 pounds per square foot.

How do you calculate live load on a deck?

How much weight can a residential floor hold?

A modern house is designed to support a floor load equivalent to 150kg per square metre (1.5kN/m2). That’s a maximum, but permissible over the whole floor area.

How much weight can my deck take?

In general, most decks can withstand 100 lbs per square foot. So if a hot tub like the one in the example is under that weight, the average deck should be able to support it.
