This 3 000 pound concentrated load if it was based upon beams every 12 feet and joists every two feet would equate out to a uniform live load requirement of 125 psf.
Garage floor load.
Garage floor parking surfaces must be made from approved noncombustible and nonabsorbent materials.
Joist span is also governed by the weight placed on the floor.
However if the attic is intended for storage the attic live load or some portion should also be considered for the design of.
Floors in garages or portions of buildings used for the storage of motor vehicles shall be designed for the uniformly distributed live loads of table 1607 1 or the following concentrated loads.
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.
Floors in garages or portions of buildings used for the storage of motor vehicles shall be designed for the uniformly distributed live loads of table 1607 1 or the following concentrated loads.
For example a floor joist at 16 spacing s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its center.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
The code also specifies minimum uniform loads of 30 psf for sleeping rooms which are unlikely to experience live loads as big as say the living room 20 psf for uninhabited attic spaces and 50 psf for passenger vehicle garage floors.
Note that some of the engineered wood product design software on the market uses the commercial code.
Dead load for residential construction is generally considered to be about 10 pounds per square foot.
2 for mechanical parking structures without slab or deck which are used for storing passenger vehicles only 2 250 pounds per wheel.
Dead load and live load.
Location and configuration of heavy loads should be looked at on a case by case basis.
Frtw fire retardant treated wood might meet with the approval.
Floor loads are described using two measurements.
2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes.
The reduction in the minimum uniformly distributed live load for passenger vehicle garage floors from 50 to 40 psf 2 4 to 1 9 kpa from asce 7 98 to asce 7 02 lessens the impact of the proposed change but should not be used as justification for the change.
Loads should be determined in accordance with this chapter.
1 for garages restricted to vehicles accommodating not more than nine passengers 3 000 pounds acting on an area of 4 5 inches by 4 5 inches.
