An additional precaution was added in rigid diaphragm analysis to prevent a node from creating multiple MPC (Multi-Point Constraint) connections to the master joint.
In the rigid diaphragm analysis, a correction (which could cause a small deviation) was made to the mass center calculation in the option "Distribute the masses of vertical elements equally to the storey they are connected to".
General improvements made

V.9.1.5.0 02/01/2026

When user-defined reinforcement was selected in a reinforced wall, the program was changing the user's selected reinforcement after calculation. Fixed.
When user-defined reinforcement was selected in a reinforced wall, the number of horizontal legs was considered as 1. Fixed so that user preference is taken into account.
General improvements made

V.9.1.4.0 17/12/2025

Even when longitudinal reinforcement in shear wall reinforcements was entered as user-defined and fixed, the reinforcements were changing after calculation. Fixed.
User-defined shear wall left/right boundary vertical reinforcements and boundary horizontal reinforcements were not being saved to file. Now saved.
In shear wall reinforcement calculation, design moments were calculated and processed based on M2 maximum and M3 maximum values and their compatible Nd values (per TBDY Article 7.6.6). The analysis has been revised to also take the most unfavorable case of M N pairs into account (such as Mr also being low in low Nd combinations).
When the shear wall Ve value was negative, the sufficient checkmark was being placed because it was less than Vr and Ve max (positive values). The comparison is now made using the absolute value of Ve.
In shear wall shear calculation, when Ve>Vr, the user had to reduce the shear wall horizontal reinforcement spacing or increase the diameter. The program has been revised to automatically make the necessary changes.
Normal force-moment interaction diagram added in Tables>Shear Wall Form.

For the case where the period calculation in the equivalent seismic load method is performed according to TBDY2018 Equation 4.26, an arrangement was made per Article 4.7.3.2 to ensure that the dominant natural vibration period Tp of the building, calculated using Eq.(4.26), is not taken larger than 1.4 times the TpA period given in 4.7.3.4 for use in seismic calculations.

This caused an incorrect large error ratio warning in buildings with foundation beams or wooden bracing on the lower storey. By comparing the storey shear force totals with the support reactions, unnecessary/incorrect warnings have been prevented.
Fixed an issue that could cause analysis to be interrupted when wall-type shell finite elements were selected.
