How much weight per square foot will a standard wood framed floor hold?
The answer to this question depends upon several criteria: 1. The span of the floor framing members 2. The 'on center' spacing of the floor framing members 3. The nominal dimension of the floor framing members (2x12 etc.) 4. The grade and species of the wood 5. Size and location of any holes or notches in the framing members A typical residential floor designed for a 10 psf Dead Load, 40 psf Live Load and a deflection criteria of L/360 (mid span deflection limited to L in inches/360): 2x12 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 17'-10". 2x12 joists at 16" on center spacing, Southern Pine #2, will have an allowable max span of 18'-10". 2x10 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 15'-5". Random thoughts: Thinset ceramic tile with mortar will add about 10 psf dead laod. Location of very heavy objects can be critical when determining a floors capacity.
How many feet are in a span?
A span is 8" or 0.67 foot. That is an informal measurement from the tip of the thumb to the tip of the pinkie on a average spread hand.
What measurements were used in ancient times?
hand,foot,span,cubit,kernels of corn,
What size micro lam beam is needed for a 16 foot span supporting a floor with 8 foot joist on either side of it?
That really cannot be answered without looking at the entire set of plans.
How many steps are equal to 500 feet?
Depends upon your personal "stride" ... the span of distance between each foot when walking normally.
