Structure > Node Support Orientation

Table of the defined structural nodes, showing their support orientations. The orientations are defined in terms of angles of a fictitious beam element defining the local coordinate system of this element (see chapter 2.3.3. of the analysis user guide).

Setting	Description
Node	Number of the currently selected node
Table of Node Coordinate Orientations	Node: Node number (allowed numbers are 1 to 99999) Supp: Code, defining whether the node has support information (yes/no) Beta: Angle between the local y axis and the default y axis as defined by definition of Alpha1 and Alpha2 Alpha1: Angle between the local x axis and the horizontal (global X-Z) plane Alpha2: Angle between the global X axis and the projection of the local x axis to the horizontal plane (X-Z plane)

Table of Node Coordinate Orientations

Node: Node number (allowed numbers are 1 to 99999)
Supp: Code, defining whether the node has support information (yes/no)
Beta: Angle between the local y axis and the default y axis as defined by definition of Alpha1 and Alpha2
Alpha1: Angle between the local x axis and the horizontal (global X-Z) plane
Alpha2: Angle between the global X axis and the projection of the local x axis to the horizontal plane (X-Z plane)

Default axis y'_L in the vertical plane through the element axis (parallel to axisY_G)

Note: The local node coordinate system is built by rotating the default global vector system. At first the x vector is rotated by Alpha2 around the global Y axis (definition range 0° to 360°. Then the vector is rotated by Alpha1 out of the horizontal plane (definition range -90° to 90°). Finally the vectors y and z are rotated around the local x axis.
