Utilizations on Members

The result tables of the Design Ratios on Members category contain the result data for the designs performed with the respective design ratios.

Result Table "Design Ratio on Members" for "Timber Design"

The member results are sorted in the tabs according to the following criteria:

• Loads (design situations, load combinations)
• Member properties (materials, cross-sections)
• Objects (member sets, members, member locations x)

Member Set No. / Member No.

For each design criterion, the number of the member set (if designed) and the member with the greatest design ratio is given.

Location x

The table indicates the x-location in the member for which the maximum design ratio has been determined. The following x-locations are relevant for the tabular output:

• Start and end nodes
• Intermediate member result points (if defined)
• Member division according to FE mesh settings for members
• Extreme values of internal forces

Stress Point No.

The design is carried out at so-called stress points of the cross-section. These locations are defined by the coordinates of the centroidal distances. All standard library cross-sections have stress points at the locations relevant for the design.

You can check the stress points in the cross-section information dialog box. To do this, click the button in the table toolbar. The 'Stress Points' tab of the info dialog box lists the stress points with their coordinates and displays them on the cross-section (see the Stress Points chapter in the RFEM manual).

Design Situation

This column names the numbers of the Design Situations for which the individual design ratios are available.

Loading

The table gives the numbers of the load or result combinations that are governing for the respective designs.

Design Criterion

This column indicates the design conditions according to the Standard. The degree of the respective design ratio is expressed by the length of the colored bar.

Design Type

Each design is identified by an identifier with a number. For example, the cross-section checks according to the Eurocode have the identifier 'SP', the stability analyses have the identifier 'ST', and the serviceability limit state designs have the identifier 'SE'. The design type is explained in the Description column.

Design Formula

You can activate this column in the Result Table Manager. It shows the equations of the standard according to which the designs are performed.

Description

Each design is explained by a short description with reference to the chapter in the standard.

Filter Results by Limit State

If the table is to display only the results for specific limit states or design types, set the corresponding filters in the Result Table Manager. For example, you can display only the results for stability designs by deactivating all 'Lines' except for Stability.

The buttons in the table toolbar also provide the option to quickly show and hide the results of specific limit states. They are accessible if designs for the corresponding limit states are available.

	Shows or hides results for the ultimate limit state
	Shows or hides results for the serviceability limit state
	Shows or hides results for fire resistance designs

Displaying Governing Design Only

Filter Results by Design Ratio

The list on the right in the table toolbar provides the option to filter the tables by design ratios. The Max option displays only the governing design for each object.

You can also use a custom filter criterion. To do this, use the Define option in the list. The Result Table Manager dialog box opens with the Criteria - Values tab. Define the condition – for example, to display only design ratios that are greater than a specific value.

Defining Filter Criteria for Design Ratio

The Filtering Result Tables chapter in the RFEM manual describes how to define conditions for the table values.

Optimize Cross-Section

If the designs for a cross-section are not fulfilled, you can have the program optimize the cross-section. In doing so, the smallest possible cross-section within the same cross-section series that meets the requirements is found. Proceed as follows:

1. Set the Input Data table category for the steel design.
2. Go to the Cross-Sections table.
3. Click into the corresponding cell of the Use Different Cross-Section for Design table column.
4. Open the list and select the Optimize option (see the Optimize Cross-Section image).
