one-way slab
one-way slab
(OP)
Two questions about 1-way slabs.
1) When are 1-way slabs preferable to 2-way slabs? I can only think of the ease of design and perhaps the geometrical requirements of a particular project, i.e. column locations.
2) When calculating live load reduction based on floor (or flat roof) area, do you consider the total floor area or a single span of the one way slab? For example, think of a continuous 1-way slab spanning beams 20' o.c. in the short direction. For the purpose of live load reduction, do you consider a single span of slab (let's say, 20' x 40') or a total floor area consisting of several such spans (e.g. 100' x 80')?

RE: one-way slab
2. I don't have my ASCE 7 here, but I seem to remember that one can't reduce LL for the design of a one-way slab. Somebody correct me if I'm wrong.

Limitations on One-Way Slabs:
The tributary area, AT, for one-way slabs shall not exceed an area defined by the slab span times a width normal to the span on 1.5 times the slab span.
