Girder Bridge A bridge constructed with wood, steel or concrete girders. The Park Bridge the inspiration for our TranBC logo is a curved steel girder bridge on concrete piers.

Constructed init is located on BC highway 1 between Field and Golden. Another type of bridge which often goes unnoticed but is actually a very common bridge type in BC is the overpass.

This bridge is made up of pre-stressed concrete box beams and supported on mechanically stabilized earth wall abutments. This stunning structure is called Kiskatinaw Bridge. Located in the Peace region, it is a steel frame bridge built in Glulam is glue laminated timber, a structural timber made out of a number of layers of timber bonded together with durable, moisture-resistant adhesive.

Floating Bridge These bridges are sometimes called pontoon bridges and they really do float. Bennett Bridge on Highway 97 across Okanagan Lake was completed in and is one of only a few floating bridges in the world. Flood arches are frequently added after the main bridge has been flooded. The foundation or base of a bridge is the element that connects the structure to the earth and transfers loads from it to the ground below.

A girder is the main horizontal support beam on a bridge. It supports the smaller beams.

However, they may also have a box shape, Z shape, or other form. Box girder bridge Girder bridges are the most common types all over the world. At its simplest, the form can be traced back to the simplest early log bridges. The two most common girder types are plate girders and box girders. A plate girder is made from separate structural steel plates instead of a single cross section. These are then welded together to create the vertical web and horizontal flanges of a beam.

A box or tubular girder is an enclosed tube with multiple walls usually made from rolled or welded steel, aluminum extrusions, or prestressed concrete. A box girder can resist twisting motions while maintaining considerable strength. A fixed arch is most commonly used on shorter, concrete bridges. A guard rail is a system used on the sides of bridges — and sometimes, the median — to keep people and vehicles from entering unsafe areas or falling off the edge.

Cable and posts only used in rural areas. Steel with wood or metal posts. Concrete barriers typically used in medians. Safety, cost-benefit, and repair-related concerns go into deciding which type of guard rail is used on a particular bridge.

Hanging systems are used to attach utility infrastructure to bridges.

This can include wiring, piping, or ductwork. Hangers can be purchased off-the-shelf or custom fabricated to meet the needs of specific projects. A pier is a raised structure that sits in a body of water to support a bridge.

The open structure of a pier allows water to pass through it, preventing pressure from building up against it. A pile is hammered into the soil beneath the bridge until the end of it reaches the hard sub layer of compacted soil or rock below. Piles hammered to this depth leverage the grip and friction of the soil surrounding it to support part of the load of the bridge deck.

Essential Question How does a structural engineer design a truss bridge to carry pedestrians from building to building over a heavily traveled thoroughfare?

One of your clients owns a hotelacross the street from a convention center. Structural analysis is a systematic study of the relationship of the material, members, and the construction of the structure when loaded to determine the resulting deflections and forces.

Static equilibrium is concerned with the special condition that exists when a body is in equilibrium and at rest when subjected to force. All objects can be deformed with the application of an external force.

The external force is called stress.
