GSA Analysis Types
Overview
GSA offers a wide range of structural analysis types
-
Static analysis
-

-
Non-linear static
-
-
Dynamic analysis
-
Modal
-

-
Analysis of applied load, applied displacements and settlements
-
Export of data to other analysis programs
-
Selective storage of results
-
Element pre-load by prestress for initial p-delta effects
Analysis stage specification:
-
included elements per stage
-
element properties per stage
-
constraints per stage
When an analysis is requested the data are checked for inter-module consistency. If errors are detected, a report is prepared and the program returns to the data editing options; if not, the program proceeds with the analysis with progress being reported to the screen throughout
Analysis control
-
analysis is specified and controlled by analysis tasks
-
default analysis task is set up automatically for typical analysis: linear static analysis of all load cases
-
explicitly defined analysis tasks are defined via the analysis wizard
-
pre-analysis data checks check for inter-module consistency, reporting to the report view
-
report view messages link to related data
-
pre-analysis checks can be invoked explicitly
-
several analysis tasks can be queued for batch analysis
Case control
-
Load cases
-
load container
-
-
Analysis cases
-
result container
-
may be described in terms of compound load cases
-
-
Combination cases
-
described in terms of compound analysis cases
-
descriptions may reference other combinations
-
results calculated for combination cases on-the-fly
-
-
Enveloping
-
described as a special combination case
-
analysis envelopes enable enveloped results to be stored
-
