In this exercise, you will open the STAAD.Pro dataset model that was supplied with this training and review the following model information that has already been specified:

Story Drift: All sections passed for story drift. This implies there is little or no lateral displacement between successive floors of the structure. It also indicates that the centre of gravity of the structure aligns with the centre of the seismic mass, therefore there is no eccentricity between the two parameters.

Soft Story: This indicates that some floors are not rigid enough to resist the base shear effects. It can be resolved by changing section size/properties and/introducing a shear wall into the structure geometry to increase the rigidity of the floor(s).

Design Results: The slide showing result output indicates that no member failed as can be observed from the result generated from the “fail” search query.
