Wall Load into Floor Load 1

[Cassidy G]

Hi! Good day, Engineers.

Can anyone help me how to convert wall load into floor load. Can you give me formula or can anyone explain it.

Let say, Pw is the weight of masonry wall given by the code in kPa or psf, psi.

I'm going to check if the slab can carry the masonry interior wall/partition wall without intermediate beam.

Then I will apply the wall loads converted to floor loads to concrete frame.

Thank you in advance. God bless.

You would have to provide more information. Is this a concrete frame or a residential lumber framed building?

First of all kpa and lb/ft are two different units of measurements ( the first is pressure, the second is distributed load)

Dead load of walls is given in kN/m of lb/ft. In residential building, most of the time this load is carried all the way through to foundation walls.

Sometimes you can have a beam directly below the wall, in which case you design the beam for the kN/m or lb/ft you compute.

Is your slab soil bearing?

Concrete two storey residential housse.

Psf or psi, I mean.

I will check if intermediate beam is necessary.

This is suspended slab

A quick solution maybe to install a wide flange steel beam directly below the wall, and adjustable steel posts on either sides.

You would also need to provide concrete footings to the post.

I highly recommend you consult a local engineer. He'd be able to compute the loads correctly, and assess the situation further.

No, Sir. This concrete structure.

Yes, Sir. Forget about foundation. I know how to design it. I'm just asking how can I apply the wall loads to beam. The wall is partition and located at the center of slab without intermediate beam.

Can you post a sketch? It sounds like you're describing a slab with a line load, which is pretty simple. If it's a one way slab, it's really basic - any concrete design textbook will cover it. A two way slab gets a bit more complex, but not too bad.

If a one-way slab, and heck even for most two way slabs, I would just take a reasonable width of slab (minimum the width of wall plus twice the slab depth, more if I have transverse slab reinforcing to help engage more of the slab) and see if it has the capacity to support the line load from the wall.
