Answer:
A key advantage of the Building Model add-on is its ability to accurately determine interstory drift, a critical parameter in seismic design. Evaluating story drift is essential for ensuring structural integrity by limiting excessive displacement, which can cause instability or damage to nonstructural components, such as partitions. With this functionality, engineers can also calculate stability factors and interstory drift sensitivity coefficients, helping to assess whether P-delta effects should be included in the seismic analysis. These effects can then be seamlessly integrated into RFEM 6, along with the Response Spectrum Analysis add-on, for a more thorough and comprehensive evaluation of the building's seismic performance.
