To Prevent Collapse: Rigid Trusses Explained
What are some examples of rigid trusses that can prevent collapse by maintaining their shape and stability under external forces?
A truss must be rigid in order to prevent collapse when subjected to external forces. Rigid trusses do not undergo significant deformation or movement, ensuring the structure's stability. Here are some examples of rigid trusses: The Warren truss is made up of equilateral triangles formed by diagonal and vertical members. These triangles provide stability and rigidity to the structure, distributing external forces evenly to prevent excessive deformation. Similar to the Warren truss, the Pratt truss consists of diagonal and vertical members. The diagonal members slope downwards towards the center of the span, helping to distribute the load evenly and maintain rigidity. The Howe truss features vertical and diagonal members that slope upwards towards the center of the span. This design helps counteract downward forces from vertical members, making the truss rigid and stable. A variant of the Pratt truss, the Baltimore truss includes additional vertical members in the center panel for added rigidity. These vertical members contribute to the structure's stability and ability to withstand external forces.Rigid Trusses for Stability
