What Makes a Cable-Stayed Structure Unique?
What is the term for a structure having vertical or inclined masts from which cables extend to support horizontally spanning members arranged in a parallel or radial pattern?
Options:
- Tensile Structure
- Cable-Stayed Structure
- Truss Structure
- Arch Structure
Final answer:
The correct term for a structure with vertical or inclined masts and cables supporting horizontal members is a Cable-Stayed Structure.
This is distinct from Romanesque architecture elements such as vaults and trusses.
The term for a structure that has vertical or inclined masts from which cables extend to support horizontally spanning members arranged in a parallel or radial pattern is called a Cable-Stayed Structure. This is a type of bridge where the weight of the bridge deck is supported by a number of cables attached to towers, also known as masts. The cables bear the load and transfer it to the towers, which then transfer the forces to the ground.
In Romanesque architecture, various elements such as columns and arches were significant. In particular, vaults of stone or brick evolved into the pointed, ribbed arch characteristic of Gothic architecture. To reinforce these structures against the outward thrust, iron rods were used.
In contrast, long houses typically had wooden trussed rafter roofs, which are load-bearing with a post-and-lintel configuration. The sharply pitched roof design, which is similar to an inverted boat, is ideal for snow-laden regions as it prevents collapse by allowing snow to slide off.
Truss Structure is another term which generally refers to a rigid assembly of beams forming a triangle network, a major support in engineering works, but it does not specifically describe a structure with cables and masts.
