Hi there
Can anyone confirm that CL14.6.2 only applies to isolated shear walls with "discontinuous edges", and does not apply to walls within a closed core box?
I find that CL14.6.2.3 is quite onerous that where stress exceeds 0.15f'c, all verticals bars needing restraint. But then in a closed box, stress could be double that amount and not require restraint?
I guess it makes sense as an isolated wall will be more likely to fail in stability, so the compression rules only apply to them, but the tension reinforcement rules apply to both boxes and isolated walls to achieve ductility.
In this sense, for ductile core boxes, these walls are designed as columns, but don't necessarily need restraint if CL11.7.4 is satisfied. But then CL11.7.4 says that all walls must be restrained in accordance with CL14.6?
