ST7-1.40.35.2 Extracting Resultant Forces and Moments from a Building
This Webnote explains how to extract actions from an entire building or portion of a building. Four related procedures are illustrated:
Finding the centre of mass of a building (in plan).
Finding the centre of stiffness (the shear centre) for a particular storey of a building.
Using staging to analyse multiple scenarios in a single model.
Finding the resultant actions on a particular storey of a building.
The first two procedures are particularly useful in seismic analysis because...
