and ICB2012 (http://tyrone.org/wp-content/uploads/2017/05/icc.i…) and ACI (http://tyrone.org/wp-content/uploads/2017/05/icc.i…)

I will attach the plain view and side view with the dimensions.

Also, I will attach the loads (dead, live, rain and wind) and the combination load.

PLEASE design the members with the concrete wall with showing step by step please and refer to where you get the information or the equation for choosing the members(steel beam) which code and method used ect.

Please show steps.

I have a starting drawing just to show you how I want it on microstation file and another for Risa 3d but I could not upload them here, If there is a way let me know so I sent them to you.

Note, I have changed the roof and make it flat with a slope.
