While CSI ETABS 9.7.4 is a masterpiece of software engineering longevity, the structural engineering industry has steadily moved forward. Modern demands such as , complex non-linear time-history analysis for earthquakes, and deep integration with Autodesk Revit mean that modern firms must eventually upgrade. Always scale to 85% of base shear from
