Solver element (1D) types
Eight different 1D solver element Types are available in Tekla Structural Designer as follows:
Beam
An element in any material, with user defined area and inertia properties, and user-definable end releases - used in all solver models for:
- Columns (any material)
- Beams (any material)
- Truss top, bottom and side members (any material)
- Mid-pier concrete wall: wall-beam, and wall-column elements
- Bearing wall: wall-beam elements
- Analysis Elements (any material) with element type: Beam
Truss
An element in any material, with user-defined cross sectional area, and pinned ends (releases not being editable) - used in all solver models for:
- Braces (any material) that have not been set as tension or compression only
- Truss internal members (any material) that have not been set as tension or compression only
- Bearing wall: wall-column elements
- Analysis Element (any material) with element type: Truss
Truss 1D solver elements are also used in linear solver models only for:
- Braces (any material) that have been set as tension or compression only
- Truss internal members (any material) that have been set as tension or compression only
Tension only
A pin ended member in any material, with user-defined cross sectional area, that can only transfer tension. This is a non-linear element which requires non-linear analysis - hence used in non-linear solver models only for:.
- Braces (any material) that have been set as tension only
- Truss internal members (any material) that have been set as tension only
- Analysis Element (any material) with element type: Tension only
Compression only
A pin ended member in any material, with user-defined cross sectional area, that can only transfer compression. This is a non-linear element which requires non-linear analysis -hence used in non-linear solver models only for:
- Braces (any material) that have been set as compression only
- Truss internal members (any material) that have been set as compression only
- Analysis Element (any material) with element type: Compression only
Linear axial spring
An element that deflects linearly when an axial force is applied, in accordance with a user-defined axial spring stiffness. These are specified as:
- Analysis Element (any material) with element type: Linear axial spring
Linear torsional spring
An element that rotates linearly when a torsion force is applied, in accordance with a user-defined rotational spring stiffness. These are specified as:
- Analysis Element (any material) with element type: Linear torsional spring
Non-linear axial spring
An element that deflects non-linearly when an axial force is applied, in accordance with a user-defined axial spring stiffness. These are used in non-linear solver models only for:
- Analysis Element (any material) with element type: Non-linear axial spring
Non-linear torsional spring
An element that rotates non-linearly when a torsion force is applied, in accordance with a user-defined rotational spring stiffness. These are used in non-linear solver models only for:
- Analysis Element (any material) with element type: Non-linear torsional spring
