Design of a Base Plate - BS 5950-1:2000

[wsg1]

Hello,

I am looking at designing a base plate for a pipe support frame using the effective area method. When it comes to calculating c I get two negative values. Does this mean the beam itself is capable of distributing the load across the concrete base and thus any size base plate can be used?

Any advise would be helpful.

Thanks,

Wsg1:
If you are going to do engineering you have to learn to speak engineering too, and ask questions with enough meaningful info., to suggest you have a vague understanding of the problem. Not that you are just following a recipe and if you could only figure out “c” you would make the best darn.... whatever. A sketch showing your arrangement and “c” and the formula that “c” is used in would help too, since we don’t all have a copy of BS 5950-1:2000, on whatever page. I’ve got a different cookbook, but I’ll bet I’ve made your cake before.

There are lots of people here willing to be helpful, and some of them are pretty darn knowledgeable too, and give darn good advice. But, we don’t have the benefit of the drawings you are looking at, so we don’t have the foggiest idea what your question really is or if you are even asking the right question or truly understand the problem you are trying to solve. Ask yourself; have I given enough info. so that someone reasonably versed on this subject gets the picture, gets the question? Could I (meaning you) even understand my own question, assuming I understand the general problem, with the info. I have given, and without the aid of a sketch or the exact formula I am trying to blindly apply?

wsg1,

Looking at BS5950-1:2000 under `column bases` section 4.13.1 it appears that `c` is a distance from the face of your column (pipe) to the edge of the baseplate. So I am not sure what `c` you are calculating.

As dhengr points out - some more clarification is required!
