Explicit time history analysis - load definition

The load curve defines the variations of the dynamic loads or the base accelerations against time. The load curve defines the load factor versus time and it is used by time history analysis. The load curve will be normalized before being used in time history analysis, i.e. the magnitude of the maximum load factor in the load curve will be unit and all other load factors on the curve are factorised accordingly.

In general the load curves used in seismic analysis are from reference curves or a database of ground motions. When selecting this option a time history must first be selected. This is a text file either in tab or comma separated form, or a PEER file.
