Wall shear areas for B1 irregularity

Hello, In a structure analysis I made, while checking irregularities, I got stuck on B1 (WEIGHT FLOOR) irregularity. In the DBYBHY (2007) regulation, wall shear areas (Ak) for B1 irregularity are defined as follows. -The sum of the masonry infill wall areas (excluding the door and window gaps) on any floor parallel to the earthquake direction taken into account. My question is: Where could I have made a mistake while creating these gaps or should I do a separate operation for this? Why does ideCAD not see these gaps? SOURCE Regulation, TD (2007). Regulation on Buildings to be Constructed in Earthquake Zones. TR Ministry of Environment and Urbanization, General Directorate of Disaster Affairs, Earthquake Research Department.

Hi, In my analysis, ideCAD finds the wall areas without taking these gaps into account when there are door and window gaps. Where could I have made a mistake while creating the gaps or should I do a separate action for this. Why does ideCAD not see these gaps.

ideCAD calculates the B1 irregularity by falling the door window gaps defined to the wall object from the wall cutting areas.

I updated the link. Let me try to explain the situation for the Y direction. Since the structure is symmetrical, I took one side and multiplied by two.

The wall load is defined for the beams that have no wall objects on them. In this case, this wall entered The wall areas calculated from the floor loads are also included in the floor effective shear area We need to specify two cases here: 1. The wall load entered on the beams whose wall object is defined is not taken into account in the calculation Ak. 2. If there is no wall object on the beam, the wall load entered in the beam settings is taken into account. The Ak value calculated from the wall load is added to the Ak value found from the wall object-window openings. In your project, it is the second case. In the beam settings, you reset the wall load values that you calculated manually You can see the wall Ak value in the ideCAD report. The program is doing it correctly. The edited project is attached. You can verify the calculation you made manually by getting the report. Note: The wall length as the wall length in the Ak calculation The distance between the node points where the r is clicked is taken. Accordingly, the value that is 1.3 in the example you added will be 1.5.
