G.17.2 Second Order Analysis

G.17.2 Second Order Analysis

STAAD.Pro offers the capability to perform second order stability analyses.

See TR.37 Analysis Specification for details.

G.17.2.1 P-Delta Analysis
G.17.2.2 Buckling Analysis
G.17.2.3 Static Geometrically Nonlinear Analysis
In STAAD.Pro, a procedure has been adopted to incorporate the geometric nonlinearities into the analysis by updating the global stiffness matrix and the global geometric stiffness matrix [K+Kg] on every step based on the deformed position.
G.17.2.4 Imperfection Analysis
G.17.2.5 Multilinear Analysis
When soil is to be modeled as spring supports, the varying resistance it offers to external loads can be modeled using a multilinear analysis.
G.17.2.6 Tension- and Compression-Only Analysis
When some members or support springs are linear but carry only tension or only compression, then this analysis may be used.
G.17.2.7 Nonlinear Cable or Truss Analysis
G.17.2.8 Advanced Nonlinear Cable Analysis
When all of the members, elements, and support springs are linear except for cable members, then this analysis type may be used.
