reinforcement-1.cde project : Relating to data entry errors: -> Inclined slab-beam system in the system The elevations of the slabs existing in the inclined system change at different angles. -> Between the columns S30-S31, there are beams at the same level on top of each other -> On the left side of the system, the slab edges that form the border of the sloping slab (the slab edges between 1 and 4 axis) ), split the beams at -140 elevation and caused the boundaries of the floor to be formed incorrectly. For these reasons, when you analyze the project, the program detects
4 rigid diaphragms . However, in the lower part, one on the left and right, one on the upper part There is a total of
3 rigid diaphragms, one of which is the inclined slab
How to fix it? Define the existing slabs and beams at the lower level in another layer.You can make corrections with layer closing, locking and unlocking commands We defined the floor-beam system at its own elevations. then define the beveled parts with the command "bevel objects". There is an example of how to do the operation in the following link (Inclined floor and beams heading):
Also, your corrected project is attached. reinforcement_yakubu.cde
Regarding the number of modes: If you do a semi-rigid aperture solution, enter the mode number around 200. (90% mass is provided in the 184th mode) In the fully rigid diaphragm, less modes are sufficient.
Regarding retrofit project: Since your project is retrofit project, use the full rigid diaphragm solution with linear performance analysis. (Full rigid diaphragm is assumed in linear performance analysis)
