Question
HI,
Am supervising a 0ne story construction in Nakuru-kenya with hollow pot slab. I have never seen it practically being constructed but given the procedure, I will work it out. I have little theory of the same and still doing research. Please help.

Answer
Hi Ibrahim,

Hollow-pot slabs are essentially one-way spanning ribbed slabs, but the gaps between the ribs are filled in so as to have a flush flat soffit for plastering. One way ribbed slabs are well covered in BS 8110, and essentially each rib is designed like a beam for bending/shear, etc.

The main disadvantage of having the pots (instead of just the ribs) is that it increases the weight, but for a single story building that does not matter too much.

Incidently, I will soon be returning home to Kenya and will also be building a house near Nakuru!
