What is a habitable bridge?
A habitable bridge. has a manifold function: to connect and to transform the existing urban or suburban landscape. Therefore, it combines the concept of connectivity, movement and habitation which has a. direct repercussion on the design and typologies of the bridges.
What are the steps in designing a bridge?
When civil engineers design a bridge, they typically use this same process:
- Identify the problem.
- Define the problem.
- Develop alternative solutions.
- Analyze and compare alternative solutions.
- Select the best alternative.
- Implement the solution.
- Evaluate the results.
What do you need to design a bridge?
Data needed for designing a bridge: A plan of the site showing all obstacles to be bridged such as rivers, streets, roads or railroads, the contour lines of valleys and the desired alignment of the new traffic route. Longitudinal section of the ground along the axis of the planned bridge with the conditions for clearances or required flood widths.
What happens after the design of a bridge?
After the approval of the design, the final design work can begin with rigorous calculations of forces, stresses etc. for all kinds of loads or attacks and then the structural detailing has to be done. The scaffolding and equipment, which will be needed for the construction of the particular type of bridge, also has to be worked out.
What do students learn in bridge design class?
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. They learn the steps that engineers use to design bridges by conducting their own hands on associated activity to prototype their own structure.
How are bridges designed one piece at a time?
Bridges are often designed one piece at a time. Each pier (columns) and girder (beams) has to meet certain criteria for the success of the whole bridge. Structural engineers go through several steps before even coming up with ideas for their final designs. First and foremost, engineers must understand the problem completely.
