~HCLPFST

 

~HCLPFST, Lab1, ChckAxis, ClassMod, ,VAL1,VAL2

Checks structural steel cross sections according to High Confidence of a Low Probability of Failure (HCLPF).

POST1: Steel Checking

Lab1

Label identifying the type of checking.

ChckAxis

Element axes (ANSYS or CivilFEM axes system) which will be taken as “principal bending axis” or “Y axis” of Eurocode3 (only for Eurocode 3).

ClassMod

Defines the set of acting forces and moments that will be taken into account in the calculation of the section’s class (only in Eurocode 3).

VAL11

Load step of seismic loads.

VAL12

Substep of seismic loads.

Notes

- A seismic RCV file must exist and be specified with ~CFFILE2 command, taking NFILE argument as NFILE=4.

 

 

This command depends on active code.

If active code is EC3:

Lab1

Description

TENSION

Tension checking (Art.5.4.3).

COMPRESS

Compression checking (Art.5.4.4).

BENDING

Bending checking (Art.5.4.5).

SHEAR

Shear checking (Art.5.4.6).

 

For Eurocode 3 checking.

ChckAxis

 Description

-Z

‘+Y’ for Eurocode No.3 = ‘-Z’ for CivilFEM (Default value).

 Y

‘+Y’ for Eurocode No.3 = ‘+Y’ for CivilFEM.

 Z

‘+Y’ for Eurocode No.3 = ‘+Z’ for CivilFEM.

-Y

‘+Y’ for Eurocode No.3 = ‘-Y’ for CivilFEM.

The ChckAxis choice can be made in different stages of the program and therefore it is recommended that the user knows the hierarchy order. This order is given next:

       1º The ChckAxis value coming from ~MEMPROP will be taken

       2º The ChckAxis value coming from ~HCLPFST will be taken

       3º The ChckAxis value as –Z

ClassMod

Description

FULL

The class is obtained considering all the forces and moments as result of the calculation.

PARTIAL

The class is obtaining only considering the logical forces and moments of the checking. (Default value).

 

If active code is N690_06A:

Lab1

Description

TENSION

Checking of members in axial tension (Chapter ND).

COMPFBK

Checking of members in axial compression (Chapter NE3).

COMPFTBK

Flexural torsional buckling checking (Chapter NE4).

BENDING

Bending checking (Chapter NF).

SHEAR

Shear checking (Chapter NG).

PLTGIRD

Plate girders checking.

BEND_AXL

Checking to Flexure + axial (ChapterNH).

BDAXSHTR

Torsion, Flexure, Shear and/or Axial Force checking (Chapter NH).

 

If active code is N690_06L:

Lab1

Description

TENSION

Checking of members in axial tension (Chapter ND).

COMPFBK

Checking of members in axial compression (Chapter NE3).

COMPFTBK

Flexural torsional buckling checking (Chapter NE4).

BENDING

Bending checking (Chapter NF).

SHEAR

Shear checking (Chapter NG).

PLTGIRD

Plate girders checking.

BEND_AXL

Checking to Flexure + axial (Chapter NH).

BDAXSHTR

Torsion, Flexure, Shear and/or Axial Force checking (Chapter NH).

 

 

Notes

- Checking is done for the element ends (cross sections or solid sections) of selected elements at the moment of command execution.

- All calculations are performed according to the active code (see ~CODESEL command).

- The description of the calculation process used can be found in the Theory Manual.

- The analysis results are stored in CivilFEM results file as an alternative.
