Question:

After I modify the lapping length of the wall in the floor settings , calculate it, why the result of the vertical bar is still the value before?How to deal with it ?

Solution:

Because in the calculation rlues , the main bar lap value is lap 1( which means it will get the value from where the lap locates), you only modify the lapping length of current floor, you should modify the lapping length of upper floor or change the lap value to lap 2(which means it will get the value of current floor).
