M. To generate load combinations per Eurocode
To generate load combinations for the Strength limit
state per
Eurocode  Basis of structural design, BS EN
1990:2002+A1:2005 (sometimes referred to as
"Eurocode 0").
The load combination generator is capable of creating load combinations per equations 6.10, 6.10a, or 6.10b found in Cl. 6.4.3.2.
The load
combination generator is capable of creating load combinations per equations
6.10, 6.10a, or 6.10b found in Cl. 6.4.3.2.
These equations specify the following combinations of loads:
$\underset{j\ge 1}{\Sigma}{\gamma}_{G,j}{G}_{k,j}+{\gamma}_{p}P+{\gamma}_{Q,1}{Q}_{k,1}+\underset{i>1}{\Sigma}{\gamma}_{Q,1}{\psi}_{0,1}{Q}_{k,1}$  (6.10) 
Alternatively, for the strength limit state, the less
favorable of equations 6.10a and 6.10b may be used:
where
$\underset{j\ge 1}{\Sigma}{\gamma}_{G,j}{G}_{k,j}+{\gamma}_{p}P+{\gamma}_{Q,1}{\psi}_{0,1}{Q}_{k,1}+\underset{i>1}{\Sigma}{\gamma}_{Q,1}{\psi}_{0,1}{Q}_{k,1}$  (6.10a) 
$\underset{j\ge 1}{\Sigma}{\xi}_{j}{\gamma}_{G,j}{G}_{k,j}+{\gamma}_{p}P+{\gamma}_{Q,1}{Q}_{k,1}+\underset{i>1}{\Sigma}{\gamma}_{Q,1}{\psi}_{0,1}{Q}_{k,1}$  (6.10b)

On the
Utilities ribbon tab, select the
tool in the
User Tools group.
The Eurocode Combination Generator dialog opens.
 Select the Equation Number to use for the generation of load combinations.
 (Optional) Specify a Start Combination Number.
 Select the Method as either:
 (Optional) Specify load Factors for use in the combination equations.
 (Optional) Click Table A1.1 to select one of the recommended values for the Permanent Action Reduction Factor, Psi (ψ_{0}).

Click
Categories to specify in which load action
classification each
STAAD.Pro load category is to be
assigned.
Action Included Loads (None) Loads of this type will not be included in generated load combinations. Permanent Gk (permanent) By default, Dead loads are included.
Variable Q (variable) By default, Live, Roof Live, Wind, and Snow are included.
Pre Stress P (prestress) No loads are included by default in this category.
 Click Generate Combinations. A confirmation dialog box opens with the status of the export. Load cases are generated with the selection equation and load case number in the title.
