- Even when shear wall longitudinal reinforcement was user-defined and locked, reinforcement was changing after calculation. Fixed.
- User-defined shear wall left/right boundary vertical reinforcement and boundary transverse reinforcement were not being saved to file. Saving has been enabled.
- In shear wall reinforcement calculation, design moments were being calculated based on M2 max and M3 max values and their corresponding Nd values (per TBDY Article 7.6.6). The analysis has been revised to also consider the most unfavorable M-N pair conditions (such as Mr being low at low Nd combinations).
- When the shear wall Ve value was negative, the "sufficient" check was being marked because it was smaller than Vr and Ve max (positive values). The comparison is now performed using the absolute value of Ve.
- In shear wall shear calculation when Ve>Vr, the user previously had to reduce the transverse reinforcement spacing or increase the diameter. Revised so the program automatically makes the necessary adjustments.

This caused incorrect large error warnings in buildings with bottom-floor base beams or timber bracing. False/unnecessary warnings have been prevented by comparing the floor shear force totals with the support reactions.

- Columns with B or H value of 0 are now automatically deleted during analysis.
- Penalty parameter selection can now be used optionally in rigid diaphragm finite element analysis. This also enables timber-beam structures to be solved with rigid diaphragm if desired. The penalty parameter should be high enough not to cause error messages in finite element analysis - e.g., 10,000 for reinforced concrete and masonry buildings, 250 for timber-beam structures.
