connecting new residential garage floor to existing basement
i am designing a suspended floor for a new residential garage. the slab will be 12'x36'. the owner plans to pour walls under 3 sides and asked about connection methods to the existing wall. from my design, the slab will be 6" thick with #8 rebars in one direction and #4 bars in the other. would drilling rebar into the existing wall be sufficient to support? what about a steel angle? i'm pretty new at this and could use some help.

a few questions first.
the existing wall,what is it made of.cmu,concrete?how thick,and how tall is the wall.
what type of reenforceing does it have?
what type of footing does it rest on?
some walls can,and some walls can not do what you are asking in this case.
we need to determine what your wall can do as is.
why the choose of the #8 bars?
i know the wall is concrete. as far as the other details, i don't have them at this time. i would imagine the wall is 6" thick and no idea about the reinforcement. is there a quick way to determine if the wall in question can sustain what i'm asking about?
after rechecking my calcs. i see that they could use #5's spaced closer if desired. do you think the #8's would be too much?
thanks
no,
the #8 bars are not too much were, i come from better safe than sorry. i am on the ouside looking in,with not even 1/1000 of the info you have on the project.but i do think the #5 bars will do. you have to make that call.
is the wall back filled on one side?
if so you have to know what size the footing is.if you are not careful here that wall could lean-in,or fall all together under the added load of the new construction.
that is why you need to answer the questions that i posed.
i am more than sure you do not want you hard work to be for nothing
thanks for the help. i will be meeting with the owner today to obtain additional information.
you're right i don't want my hard work to be for nothing and i want to make sure it's done correctly. not so the owner can save a buck.
thanks again.
