# How can the deformation of a structure be asked for?

The displacements of the 1D and 2D member in the structure can be asked for separately, as well as the deformation of the structure as a whole. You will find here an overview of the different types of results.

## 1) deformation of the 1D members

Results > Beams > 1D deformations, value u_z:

Coordinate system is optional: member, global or principal

In case of member coordinate system (LCS), the local z axis (= the blue axis) of each beam is oriented differently. This means that e.g. for the columns the deformation u_z represents a horizontal deformation, while for the transverse beams it represents a vertical deformation.

Values can be switch to U_total which means that it represents the global deformation of the 1D members, namely the combination of u_x, u_y, u_z, phi_x, phi_y and phi_z.

If the type of values is switched to Relative deformations then the deformations are relative to a reference line.

## 2) deformation of the 2D member

Results > 2D members > 2D displacement, value u_z:

Coordinate system is optional: LCS mesh element or global

Values can be switch to U_total which means that it represents the global deformation of the 2D members, namely the combination of u_x, u_y, u_z, phi_x, phi_y and phi_z.

## 3) Deformation whole structure

Results > 3D displacement, value U_total

This is a deformation of the whole structure (1D + 2D members).

TIP: In case of huge structure is good to turn on option Wireframe in the properties. The process of refreshing results will be much quicker but without displacement in 3D (only axis will be displayed).

## 4) displacement of the nodes

Results > Displacement of nodes, values U_x, U_y, U_z, phi_x, phi_y, phi_z and U_total.

In this case, the deformation of nodes is displayed in GSS by arrows (the direction of the deformation) with values.
