Concentrated load on slab
Concentrated load on slab
(OP)
Can anyone suggest a good book, reference material etc., to deal with calculating moment, shear, etc as a result of point loading a concrete slab. I just realized I've only ever dealt with beams. Even my old engineering texts have alot on beams but nothing about concentrated loads on slabs.

For bending moments, try the yield-line (also called Johansson's) method to get a first estimate of bending moments.

RE: Concentrated load on slab
b_ef = b + 2.4*a*[1-(a/L)]
where:
- 'b_ef' is the effective width
- 'b' is the load width
- 'a' is the perpendicular distamnce from the nearer support to the section under consideration
- 'L' is the clear span of the slab
If the load width, 'b_ef', is conservatively assumed to be 0 and the concentrated load is at midspan, then the effective width of the slab is 60% of the clear span, 'L'.
