The stiffness multipliers used are displayed in the Shear Wall/Wall Bottom End Section Forces table.
Timber shear wall strength calculation was done according to TBDY2018; it can now also be done according to the ABTHYE code.
Timber shear wall connection stiffness and properties can now be entered in the wall properties form.
The “” is not a floating point error that could occur during multiple wall property changes has been fixed.
An Access violation error that could occur in the Draw Foundation Plan option has been fixed.
When analysis error ratio was calculated, if torsion-induced finite element analysis was automatically repeated, support reactions were not reset on a case basis, causing a wrong error ratio warning. Fixed.
General improvements made

V.9.1.6.0 09/01/2026

Jacket eccentricity can now also be considered in frame finite element analysis.
In jacket Vr calculation, computation was done over wall length; calculation over jacket length is now provided.
When 2 jackets are adjacent to a wall, the shear force the wall cannot carry (Vdresidual) was being divided by 2 and distributed to the jackets. It is now distributed considering their stiffness.
Additional measure taken to prevent a node from creating multiple MPC (Multi-Point Constraint) connections to the master joint in rigid diaphragm analysis.
Sign correction made during SAP2000 import that does not affect analysis results.
For one case, the issue where a window on a 90-degree axis did not detect the adjacent fictitious jacket (not creating layered Shell during SAP2000 export) has been fixed.
In rigid diaphragm analysis, a correction (which could cause a small deviation) was made in mass center calculation in the option "Distribute vertical element masses equally to the storeys they are connected to".
General improvements made

V.9.1.5.0 02/01/2026

In masonry building retrofitting, the strengthened wall Vrmax calculation was based only on jacket compressive strength; the wall compressive strength is now also considered.
For the case where shear forces on jackets are calculated by finite elements, the performance report was using shear forces on jackets connected to insufficient-strength walls from classical analysis results. Fixed.
When user-defined reinforcement was selected for reinforced walls, the program changed the user's selected reinforcement after calculation. Fixed.
When user-defined reinforcement was selected for reinforced walls, the number of horizontal arms was being taken as 1. Corrected to respect the user's preference.
General improvements made

V.9.1.4.0 17/12/2025

In shear wall reinforcement, even when longitudinal reinforcement was user-defined and locked, the reinforcement was changing as a result of calculation. Fixed.
User-defined shear wall left/right boundary vertical reinforcement and boundary horizontal reinforcement were not being saved to the file. Now saved.
In shear wall reinforcement calculation, design moments were calculated based on M2 max and M3 max values and corresponding Nd values (per TBDY Clause 7.6.6); the analysis has been revised so that the most unfavorable case of M-N pairs is also considered (e.g., low Mr at low Nd combinations).
When the shear wall Ve value was negative, it was being marked sufficient for being smaller 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 make the necessary changes automatically.
Axial force-moment interaction diagram added in Tables>Shear Wall/Wall Form.
General improvements made

V.9.1.3.0 08/12/2025

In SAP2000-integrated response spectrum analysis, the modal amplification factor was calculated from the ratio of the sum of bottom storey element section forces to the base shear force. Since this could cause issues in buildings with half basements, the ratio was changed based on support reactions occurring in SAP2000 response spectrum analysis and equivalent earthquake load base shear force.
A calculation report has been created for the seismic force amplification per TBDY2018 4.8.4.1 in SAP2000-integrated response spectrum analysis.
In SAP2000-integrated response spectrum analysis, building dominant periods were calculated based on maximum mass participation ratio and the dominant direction of the mode. With the revision, calculation is now based only on maximum mass participation ratio.

In fully rigid diaphragm analysis, wind loads were taken based on max building dimensions; automatic wind loads can now be applied based on wall angle by specifying edge axis walls (in shear wall/wall properties, the option for shear wall on left/right/bottom/top edge axis must be specified for exterior facade walls).
In rigid diaphragm-free / Semi-rigid diaphragm analysis, wind load can now be applied to the structure on edge axis walls based on wind direction by specifying edge axis walls (in shear wall/wall properties, the option for shear wall on left/right/bottom/top edge axis must be specified for exterior facade walls) and considering wall angle.

Element groups were not being saved to the data file after assignment. Group assignments are now saved to the project data file and can be used in subsequent sessions.
For cases where another material is desired instead of OSB, timber wall cladding material (e.g., lath plaster / battened panel) can now be manually assigned.
In the "Convert slab to rib" command, a selection group is now automatically created for the split and derived elements and assigned to the same group.
When there are elements with near-zero length, selection could not be made on the modeling screen. Fixed.

In SAP2000-integrated analysis under TBDY2018, when the element axial force calculation option was set to classical, the vertical stress result from classical calculation was being used instead of the SAP2000 result as normal stress in shear force calculations. Fixed. Since the finite element method is mandatorily used under RYTEİE 2018, this issue does not affect risky structures.
In SAP2000-integrated analysis, slab cladding load was being counted twice as normal stress in shear force calculation. Fixed.
In SAP2000-integrated response spectrum analysis, the live load factor in the mass source definition was being taken as 0.3. For buildings with live load participation factor different from 0.3, it is now taken based on the live load participation factor.

For cases where timber and RC slabs are used in the same building, in the SAP2000-supported "some slabs rigid diaphragm, some slabs not" option, only the 1st slab material was being considered in building mass calculation reports.
