Which is a false statement regarding hollow-core slabs? Select one: a. They are lighter than solid slabs. b. They are two-way structural elements. c. They span intermediate lengths. d. They are often 4 ft wide e. They can be produced as an extrusion.

B

Explanation:

- Hollow core slabs are usually one way slabs supported at two opposite sides. This is because the caved out volume from the slab weakens the structural integrity to point loads as it is for two way slabs with support on all four edges. Hence, the two supports on edges distributes the loads along the edges, keeping the stress induced in the slab to be uniform where the mass/length ratio of the slab is greatest providing structural integrity for high distributed loads, low cost, and mass production.
