In thin and long structures, if you make the carrier system strong in the short direction, it will help to ensure the relative floor displacement
Flaky frames have a negative effect. Making the frame continuous by adding beams at the axles where the frame is discontinuous can help to provide relative story offsets.
If the superstructure-foundation interactive solution is made, the floor horizontal coefficient is effective. Check if it has been entered correctly. In cases where the superstructure-foundation interactive solution is made, increasing the foundation thickness can help provide relative story offsets.
Increasing the beam dimensions can contribute to the relative story offset.
Provided that it is built on site , TBDY may consider applying Article 4.9.1.3b . There is an option in the analysis settings. Application of TBDY Article 4.9.1.3b increases the relative floor offset upper limit by 2 times.
