Getting started
GSA is a program for structural analysis, and it is assumed the user has a knowledge of structural engineering concepts. The GSA help is aimed at explaining the features and use of the program but not the structural concepts expressed in the program. A new user to GSA should refer to the Getting started manual which gives a worked example on the use of GSA.
