Design Ratios on Surfaces

The result tables of the Design Ratios on Surfaces category contain the result data for the design checks carried out with the respective design ratios.

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

  • Loads (design situations, load combinations)
  • Surface properties (materials, thicknesses)
  • Objects (surfaces, FE mesh points)

Surface No.

For each design criterion, the number of the surface with the highest design ratio is specified.

Mesh Node / Element No.

The number of the FE mesh node for which the maximum design ratio was determined is specified.

Info

If you have selected the “Calculate results in grid point” option in the Global Settings dialog box, the numbers of the grid points are listed in this column. The results are then related to the surface grid.

Mesh Node Coordinates

The three columns display the global coordinates X, Y, and Z of the FE mesh nodes.

Design Situation

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

Loading

The numbers of the load or result combinations that are governing for the respective design checks are specified.

Layer Side

The equivalent stresses are analyzed for the following points of the surface cross-section:

  • Top
  • Middle
  • Bottom

Info

If the local z-axis is aligned downward in the local-axes model base data, the upper side is located on the surface side in the direction of the negative z-surface axis (−z), and the lower side is located in the direction of the positive z-axis (+z). If the local z-axis is oriented upwards, this definition is reversed.

You can show or hide the surface axes using the Local axis systems of surfaces on/off entry in the surface shortcut menu. Alternatively, use the "Navigator - Display" (Model → Basic Objects → Surfaces → Surface Axis Systems x, y, z).

Design Criterion

The design conditions according to standard are specified in this column. The degree of the respective design ratio is expressed by the length of the colored bar.

Info

The stress analysis is based on the equivalent stresses σv, von Mises.

Type of Design

Each design is designated by an identifier with a number. For example, the ultimate limit state design checks according to Eurocode have the identifier “UL”, the stability analyses have the identifier “ST”, and the serviceability design checks have the identifier “SE”. The type of design is explained in the Description column.

Design Check Formula

You can activate this column in the result table manager. It specifies the equations of the standard according to which the design checks are carried out.

Description

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

Tip

The design check details for a specific design ratio can be displayed by clicking the Design check details button or by double-clicking on the line.

Filtering Results

The chapter Design Ratios on Members describes how you can filter the results by limit state and design ratio.
