When the analysis error ratio was being calculated, if the finite element analysis was automatically repeated due to torsion, the support reactions were not reset on a case basis, causing an incorrect error ratio warning. Fixed.
General improvements made

V.9.1.6.0 09/01/2026

Jacket eccentricity is now also taken into account in frame finite element analysis.
In Vr calculation of jackets, the calculation was being done over the wall length; it has been changed to be calculated over the jacket length.
When there were 2 jackets in the wall vicinity, the shear force the wall could not carry (Vdresidual) was being divided by 2 and distributed to the jackets. It has been arranged to be distributed considering their stiffnesses.
Additional precautions were taken in rigid diaphragm analysis to prevent a node from creating more than one MPC (Multi-Point Constraint) connection to the master joint.
A sign adjustment that does not affect the analysis results was made during SAP2000 import.
The problem of a window on the 90-degree axis not detecting the neighboring fictitious jacket (not creating a layered Shell when exporting to SAP2000) was fixed for one case.
In rigid diaphragm analysis, a correction (which could lead to a small deviation) was made in 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

In the Vrmax calculation of strengthened walls in masonry building retrofitting, the calculation was being done only over the compressive strength of the jackets; the wall compressive strength is now also taken into account.
For the case where shear forces on the jackets were calculated with finite elements, the shear forces on jackets connected to walls with insufficient strength in the performance report were using values from the classical analysis result. Fixed.
When user-defined reinforcement was selected in a reinforced wall, the program was changing the reinforcement selected by the user as a result of the calculation. Fixed.
When user-defined reinforcement was selected in a reinforced wall, the number of horizontal legs was being taken as 1. Fixed so that the user preference is considered.

Even when longitudinal reinforcement in shear walls was entered as user-defined and fixed, the reinforcement was changing as a result of the calculation. Fixed.

In shear wall reinforcement calculation, design moments were being calculated based on M2 maximum and M3 maximum values and Nd values compatible with them (according to TBDY Article 7.6.6); the analysis has been arranged to also consider the most unfavorable case of M-N pairs (such as Mr also being low in low Nd combinations).
When the shear wall Ve value was negative, since it was smaller than Vr and Ve max (positive values), the "sufficient" check was being marked. 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 its diameter. The program has been revised to automatically make the necessary changes.
An axial force-moment interaction diagram was added in Tables>Shear Wall Form.

In SAP2000-integrated analysis, in some cases, the problem of analysis being performed based on internally calculated force values instead of SAP2000 sectioncut results was fixed.
In SAP2000-integrated response spectrum analysis, the modal magnification factor was being calculated from the ratio of the sum of element section effects of the lower storey and the base shear force. Since problems could occur in structures with semi-basements, the ratio was changed to be based on the support reactions occurring in SAP2000 response spectrum analysis and the equivalent seismic load base shear force.
A calculation report was created for the seismic force magnification performed according to TBDY2018 4.8.4.1 in SAP2000-integrated response spectrum analysis.
In SAP2000-integrated response spectrum analysis, when calculating building dominant periods, the calculation was being performed based on the maximum mass participation ratio and the dominant direction of the mode. With the adjustment, the calculation is now performed based only on the maximum mass participation ratio.
General improvements made

V.9.1.0.0 18/11/2025

For the case where the period calculation in the equivalent seismic load method is done according to TBDY2018 Equation 4.26, an arrangement was made in accordance with Article 4.7.3.2 so that the maximum value of the dominant natural vibration period Tp of the building, calculated with Eq. (4.26), to be considered in the seismic calculation, is not taken as more than 1.4 times the TpA period given in 4.7.3.4.

The error ratio in finite element shear force was calculated from the difference between the sum of shear forces of the lower storey vertical bearing elements (shear wall/wall and column) and the sum of storey shear forces. This caused incorrect large error ratio warnings in buildings with foundation beams or timber bracing on the lower storey. Unnecessary/incorrect warnings were prevented by comparing the sum of storey shear forces with support reactions.

Columns with B or H value of 0 are now automatically deleted in analysis.
The penalty parameter selection in rigid diaphragm finite element analysis can now be used optionally. With this, structures with timber beams can also be solved with rigid diaphragm if desired.
