Structural - Theory of Structures

Support the load by resisting being bent under the load's pressure.

• Beams
• Columns
• Posts
• Footings

Offers a constraint against rotation in any direction, and it prevents movement in both horizontal and vertical directions.

• Fixed Support
• Pin Support
• Roller Support
• Free Support

Allows rotation about any axis and translation (horizontal movement) in any direction parallel to the surface on which it rests. 

• Roller Support
• Fixed Support
• Pin Support
• Free Support

Allows rotation about any axis but prevents movement in the horizontal and vertical directions.

• Pin Support
• Fixed Support
• Roller Support
• Free Support

Rigid structural element that extends horizontally and is supported at only one end.

• Cantilever Beam
• Fixed Beam
• Simple Beam 
• Overhanging Beam 
• Propped Beam

Rests on two supports and is free to move horizontally.

• Simple Beam 
• Cantilever Beam
• Fixed Beam
• Overhanging Beam 
• Propped Beam

Type of beam in which the end proportion of the beam extends more from the support.

• Overhanging Beam 
• Cantilever Beam
• Simple Beam 
• Fixed Beam
• Propped Beam

A cantilever beam for which one end is fixed and other is provided support, in order to resist the deflection of the beam.

• Propped Beam
• Cantilever Beam
• Simple Beam 
• Overhanging Beam 
• Fixed Beam

Supported between two fixed ends.

• Fixed Beam
• Cantilever Beam
• Simple Beam 
• Overhanging Beam 
• Propped Beam

Those that rest over three or more supports, thereby having one or more redundant support reactions.

• Continuous Beams
• Fixed Beam
• Cantilever Beam
• Simple Beam 
• Overhanging Beam
