CPA/STRESS calculates stress interaction ratios at defined points of
structural member cross sections given the following as input:
 |
Cross sectional
properties (from CPA/SEC2000) |
|
Member forces
(from SAP2000 finite element model output files) |
|
Material yield
stress |
|
Various Stress
Factors to compute an allowable stress
 |
Safety
reduction factor applied to yield stress, FFA |
|
Allowable
stress increase factors |
|
Omega factors
(optional; see CPA/OMEGA and CPA/FRAMEBUCKLING) |
|
|
User defined
load combinations |
