archeng59, The column is encased in concrete, but the flange of the column that is on the inside of the building only has the 3.5" over encased concrete cover. Hopefully this makes more sense. Thanks.

I am trying to get a bit of opinion based on experience. I have some columns that have approximately 3.5" of concrete cover. What is the feeling to using isolation joints or not using them in this situation. I am thinking they are still needed because concrete will tend to crack and 3.5"...

civilperson, Thanks for the claification. I will surely look at using the basement wall rather than the retaining wall.

StructuralEIT, Thanks again for the advice. I'll be sure to consider this in my analysis.

Sorry about the confusion. Let me try to clarify this is a bit. The columns do not sit on the wall, they go to the base of the wall and sit on the foundation. StructuralEIT your question is a good one so I shouldn't have to worry about the column load in the wall design. On the other hand if...

Case 1: I am trying to design a concrete basement wall and I have columns offset from the wall 10" all the way down to the footing/base of wall. I thought that I could use the column load x the "e=10" to get a point load moment and add it to the lateral load moment to design the wall. Would...

Thanks for the input. Some helped to refresh my memory and the others were different ways to go about it.

I am trying to design joist spacing under drift load. I know its more of a trial and error to find the space that works but I can't remember how to go about doing this. Does anyone have any good examples to share or where I can find one. Thank you.

UcfSE, Thanks for the input. It is greatly appreciated.

I am designing a building where I need to used shear walls at various loacations along the building wall. In finding the shear (v) I used the [uniform loading x tributary width between shear walls]/2 and in calculating the stress I used the length of wall as the (d) factor. (M/Vd) Would this...
