Does any body know how to design a footing for CIP facing of permanent solider pile wall?

Thx

yes, would you like to hire me?

Generally I would expect the facing to be attached to the soldier pile instead of resting on a footing.

Geopavetraffic,

The facing will be attached to the soldier pile. But, is it necessary to design a footing for CIP facing?

Thx

Generally, if the facing is attached to the pile, there is no need to have a footing. However, the devil is in the details and the designer of record needs to look at this.

We have seen shotcrete facade using shear studs but not cast in place concrete. Generally, you need to look at the earth pressure on the bottom 3 ft of the shored height plus any surcharges and design it to span horizontally. The shotcrete lagging is proportioned as a beam with rectangular or trapezoidal loading- generally in the 250 to 400 psf range but it depends on the shored height and the magnitude of the surcharge loads. You then need to incorporate vertical joints in the finished wall plus Mira Drain. Try to allign the vertical joints with every other soldier beam web. It is easier to just use precast concrete lagging.

Dear friends,

Thank you all for your valuable suggestions.

Initially, I didn't consider the footing for the CIP facing and I designed the CIP facing as one-way slab. Now, I'm getting several inputs from contractor and other team members regarding the footing.

Thanks

The facing can be designed to hang from the soldier beams. However, I usually install a level work pad below the wall facing. The pad is about 2 feet wide and one foot thick, lightly reinforced if reinforced at all. The work pad provides a stable, level base upon which the wall forms can be placed and aligned. The work pad need to support the weight of the concrete forms, reinforcing steel, and wet concrete before the concrete hardens. Usually, for a 1 foot thick wall facing, this load is not very great when spread over a 2 foot wide footing work pad. Because of the work pad and wall facing dimensions, the work pad concrete should be totally in compression (therefore, little or no resteel), with no flexure.

I agree with PEinc.
