Shoe Footing Design

This should be in the Civil Engineering section.

No, you cannot do this.

Why would you even ask?

Give this folly up NOW!

Forget this insane idea and hire a civil engineer or someone with at least a little experience in designing things that they can see.

We are an anonymous forum and have no idea what you are even attempting to do.

I cannot:

Building code applies for your location and I have no idea. What does the soil look like there? How high will the stairs be? How high will a step be? You could try to find some soil stability figures, calculate the weight of your construction and go from there for the shoe surface. Some area's require deep foundations.

You do not have to get everything inspected? If yes, get a plan designed locally.

Hi! The building is in north-east of Hyderabad city. Excavated soil top is hard Murray to disintegrated rock. Stairs are dog-legged standard with 11" thread and 6" risers with 3'6" mid landing and width of the flights. Can send the pictures.

Design isolated footing for housing or building in DOCUMENT ...

Some people have more to explain here:

Take the scheme to a local building designer and get that individual to carry out the design. Submit the drawings to the local authority's Planning Office for approval. Pay for it, and accept that in so doing that individual carries the liability should it go wrong_.

Why not demolish the existing sump and make space to construct a footing type which anyone would typically use for this purpose (stair case pedestal, right?) in your locale?

Special foot designs are normally only considered if there are more permanent obstructions in the way.

Build a better sump somewhere else.

.......have you considered doing this in steel instead?

Can you post a sketch?

First off, what is a "shoe footing"? That must be a local term. Are you describing a shared footing, aka combined footing, that supports more than one column?

I believe everyone who preceded me has already said what I needed to say.

But, I might add that we do not know many many factors concerning your building, as well as the soil conditions and it's strength.

We also do not provide FREE engineering design services for many reasons, for obvious reasons, one of them is liability should you or your building contractor screw up royally resulting in the entire house of cards crumbling to the ground maiming and/or killing people + property damage.

You need to hire a local structural engineer that knows the local building codes (if they exist at all), materials, underlying soil conditions, and how your building was constructed.

I believe the shoe-footing is an eccentrically loaded pad footing. However, the question is ambiquious or at least unclear to answer. Maybe a plan would help in this case. The questioner here shall post a plan to understand what he needs help on, especially when he / she mentions existing structure; else there are plenty answers & links here here to ponder upon.

Don't know why you bother to ask the question here , the standard of construction in your city and your country in general is dependant on no regulation at all. I wonder if it might be because of all the collapses and dead bodies you seem to be getting lately. Trying to get a how to do it from this forum is at best dishonest and at worse criminal negligence. PAY a structural engineer to look at the situation and if they say NO accept it

I for one do not wish to contribute to the shoddy way your goverment runs it's civil construction.

Yes, a spread footing can be designed for your application. Unless you are a registered professional engineer, I would strongly recommend that you get the services of a reputable engineering firm to do this for you. There will be lots of different codes which will likely apply, everything from local(municipal) to county, state and sometimes even federal, and, you need someone who is familiar with each one that does apply. When you have found such a firm or person, they should do some soil sampling to see what the bearing strength of your soil/fill is and then should come up with a complete plan of what has to be done including any underpinning required prior to final installation of your footings. This is not a "weekend" project if done properly. One last thing, if you do not do it properly and you do have an "accident" that does structural damage, you will not have any insurance to do any repairs - check the riders in your home insurance policy.

You can ''design'' anything you want to, but the question remains, ''Should you?''

If (you) are not a licensed, reputable, specifically-experienced, structural AND foundation engineer, then you should immediately hire consultants that ARE...

Amazing technique.
