Thank you so much Sir

Dear Teacher, how stiffness for each floor can be calculated manually to observe stiffness irregularity check?

[@quakescodes1142]

It is the sum of individual stiffnesses of all the columns present on that floor. You may compute the same in each direction using the formula, which depends on end conditions.
