I, too, would like todo away with an interior wall, but only halfway down and have a nee-wall with a post at one end. Is this feasible? thank you for any replys.

Anything is feasible. It just takes some money.

Be sure to understand what you are doing.

The current wall load is shared along the entire wall length. If you remove the center section and place a beam to support the area removed, you now have moved the load to the remaining wall or posts that are left. This increases the amount of weight this smaller area must support. Now it gets tricky.
If the load is directed over lets say columns located in the basement. This load is now transfering directly onto the footing supporting the column. More on this later. However this load most likly will not end up over the column but somewhere over the support beam in the basement. This beam was designed to hold the weight of the wall above across its entire length from post to post. You now have put additional weight somewhere in the middle of the beam which will then deflect down because of the pressure placed upon it. You may need to add a support post under the new load area. Of course doing so will require a new footing to support the new post. Do not set the post on the floor as its not a structural part of the basement.
Now to the load being directly over the old post. The footing that supports this post was sized to hold up the weight placed upon it based on shared loads across the entire beam it supports. Once you move the load to one side or another the load profile changes and the support for the post will also change. Sometimes for the best, but most of the time not so.
It is strongly suggested that a professional engineer or designer determine what size beam is needed where your opening the wall at. And what is going to be required to support the remaining wall area that is holding up the new beam. Its not that hard to figure out. But if its done wrong. You may not see it right away, but over time things will begin to settle and crack. Not something you want to happen after spending lots of cash doing the job and then have to fix it.

Home Care Club has described perfectly what must be considered in doing what you propose, and by the way, we do not know each other except for in this forum.

I often tell my clients "anything you can say in words can be done...the question is what will it cost!" Another way of saying just what Home Care Club siad at the top of his message.

Thank you for your prompt response! I forgot to mention that there is a door that willbe taken out but the one endwill remain. This should help with support. Does this make a difference in construction? Thank you again.

It all depends on where the loads will be coming down, and what they are coming down on. What you would be doing is converting uniform load to concentrated loads. Someone has to evaluate the concentrated loads and then determine what will be needed to carry them. Skyhooks don't count, there has to be a clear and proper path from the ends of the beam or beams to the earth, and whatever lies between has to be investigated for its ability to accept and transfer the loads until they reach the earth, and that includes basement or crawl space column footings that no one can see. A professional will know what assumptions to make, and how to trace the load paths so that no skyhooks will be needed. So, everything matters, but without seeing all the conditions which are affected by what you want to do, that's about all that can be said.
