Boundary Elements for Shear Walls

[bertiskorny]

How do I get ETABS v9 to design the boundary elements for shear walls? I want concentrated longitudinal steel and transverse reinforcement? Thank you.

If you assign a seismic zone to the model, it will calculate your minimum boundary zone for you (function of Pu/P0 etc..)-

What I do after that is proportion the steel to fill the required boundary zone, and minimum steel otherwise; (of course depending on the controlling loading scenario, I might end up packing the segment full of steel..)

Short answer: ETABS is not detailing software, it's analysis software, it's your job to quantify and interpret the FEA results- and to specify reinforcement accordingly.

Using general section, define the vertical rebar yourself and let etabs check your design.
