result:members in linear compression bending not certified

Last update: 31.07.2026

Version: 0.0.0

Description

This operator is a non-certified example of buckling resistance verification for the compression and bending members for Class I, 2 and 3 cross-sections. It is only provided as an example if you want to develop your own compute norm operator. This norm is linear summation of the utilization ratios of compression members and bending members. The results computed by this beta operator have not been certified by ANSYS. ANSYS declines all responsibility for the use of this operator.

Inputs

This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

Pin number Name Status Expected type(s)
0 time_scoping scoping, vector<int32>, int32
1 field_yield_strength Required field
2 field_end_condition data_sources, field
3 streams streams_container
4 data_sources data_sources
5 manufacture bool
6 partial_factor double
7 mesh Required abstract_meshed_region
8 bending_moment_y Required fields_container
9 bending_moment_z Required fields_container
10 axial_force Required fields_container
11 class_cross_section Required bool
12 fabrication_type bool

time_scoping (Pin 0)

field_yield_strength (Pin 1)

  • Required: Yes
  • Expected type(s): field

This pin contains field of beam's Yield Strength defined by the user.

field_end_condition (Pin 2)

This pin contains file csv or field of beam's end condition defined by the user. If no input at this pin found, it would take end conditions value of all beams as 1

streams (Pin 3)

result file container allowed to be kept open to cache data.

data_sources (Pin 4)

result file path container, used if no streams are set.

manufacture (Pin 5)

  • Required: No
  • Expected type(s): bool

Manufacturing processus:hot finished if TRUE or cold formed if FALSE. Default value : hot finished.

partial_factor (Pin 6)

  • Required: No
  • Expected type(s): double

partial factor for resistance of members to instability assessed by member checks. Default value: 1.0

mesh (Pin 7)

Mesh containing beam's properties defined by user

bending_moment_y (Pin 8)

Fields Container of bending moment on axis y defined by user

bending_moment_z (Pin 9)

Fields Container of bending moment on axis z defined by user

axial_force (Pin 10)

Fields Container of axial force defined by user

class_cross_section (Pin 11)

  • Required: Yes
  • Expected type(s): bool

Selection for a cross-section. True: Class 1 or 2 cross-sections. False: Class 3 cross section. If the user defines the cross section as class 1 or 2, the section modulus would be plastic section modulus. If it's class 3- cross section,the section modulus would be elastic section modulus

fabrication_type (Pin 12)

  • Required: No
  • Expected type(s): bool

Selection of fabrication's type if there are beams I in the structure. TRUE: Rolled Section, False: Welded Section. Default: Rolled Section.

Outputs

This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing. Each output is detailed in the sections that follow the table.

Pin number Name Expected type(s)
0 buckling_resistance_linear_summation_utilization_ratios fields_container

buckling_resistance_linear_summation_utilization_ratios (Pin 0)

Linear summation of the utilization ratios in all members submitted under a combination of both bending and compression. These factors should be less than 1 and positive.

Configurations

This operator supports configuration options that modify its behavior.

mutex

  • Expected type(s): bool
  • Default value: false

If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads.

This operator can be accessed through scripting interfaces using these identifiers.
