Freestanding Wall Design

Freestanding Wall Design

Freestanding Wall Design

(OP)
Hi,

I have to design a 2.5m cavity wall as a free standing wall.

Can I assume that each leaf will take different lateral load values as the inner leaf is 215mm and the outer leaf is 100mm. So in theory the inner leaf will attract twice the load as the outer leaf as it's twice as stiff.

The cavity is large at 180mm between leafs.

Anyone do anything like this before?

BS 6399 Part 2 calcs tell me I have 1.5kN/m2 suction on the wall so I think this wall will fail anyway.

Any thoughts welcome.

John.

RE: Freestanding Wall Design

You can try to design some cantilever reinforced masonry piers every 2.0-4.0m to provide your lateral stability. Then the rest of the wall can span horizontal between the peirs

RE: Freestanding Wall Design

A cantilevered 2.5m high wall, resisting 1.5 kPa, must be reinforced. So I would reinforce the thicker leaf and brace the other leaf off the reinforced one.
