Hello,
I am designing a shear wall according to CSA A23.3-2019 using S-Concrete. The wall is a segment of a core wall (each leg is designed separately). Because the wall is laterally supported by concrete flanges, the longitudinal reinforcement is considered restrained against spalling as per CSA A23.3-19 Clause 11.2.10.5, and therefore the spalling factor may be ignored.
Unfortunately, S-Concrete does not provide an option to overwrite or disable the spalling factor.
Additionally, S-Concrete automatically uses an effective shear depth of 0.8 Lw; however, according to the code definitions:
- dv: effective shear depth, taken as the greater of 0.9d or 0.72h, and for walls need not be less than 0.8 Lw;
- d: distance from the extreme compression fibre to the centroid of tension reinforcement (but need not be less than 0.8h).
Considering these definitions for d and dv, the effective depth may be greater than the fixed value of 0.8 Lw used by the software.
I would appreciate it if you could address these two concerns.
Regards,
Moe Masumi
