Capacity module

Capacity module

In the VMTK the capacity of the structures is defined through bilinear, trilinear or quadrilinear backbones. The capacity module processes capacity curves in the acceleration-displacement response spectrum (ADRS) format (i.e. spectral displacement vs spectral acceleration).

Using the GUI

The user is capable of input the capacity data directly on the GUI only being required to populate the proper fields with the capacity data (i.e. spectral displacement and spectral acceleration) separated by commas.

Import from csv

The capacity data can also be imported from csv files containing two column arrays with the capacity coordinates. A benefit of this option is that users can explicitly model the building-to-building variability by introducing multiple capacity curves for the same building class as horizontally stacked arrays.
