AD.2006-1004.1.3 New NRC 2005 Seismic Code

A new seismic definition module has been added to the STAAD.Pro Loading Definitions.

This is to provide the user a tool to calculate and distribute the equivalent static loads produced by an earthquake that should be considered in a building as defined in the ‘National Building Code of Canada 2005 – Volume 1’, Section 4.1.8. This is also known as the NRC 2005 Seismic provisions.

This option has been added to be in addition to the previously available 1995 version of the code.

The NRC 2005 seismic provisions can be added using the Seismic Definitions dialog from the Definitions option in the main Load dialog box and selecting CANADIAN NRC – 2005 from the type pull-down list.

Once all the required values for the parameters have been defined, then clicking on the Add button will add the data to the model such that it is ready to be used in seismic load cases.

For full details of the command structure for the NRC 2005 parameters see Section 5.31.2.11 of the Technical Reference manual .
