Study Notes
Introduction to Bridge Engineering (Part 1) - CIVL3811
- Course offered by the School of Civil Engineering, Faculty of Engineering, The University of Sydney
- Focuses on bridge design and construction
- Introduces various bridge types, construction methods, and concept design
Terminology
-
Bridge types: Different types of bridges are covered, including, but not limited to:
- Super T bridges
- Super T beams
- Box girder bridges
- Cable-stayed bridges
- Arch bridges
- Super T bridges
-
Construction methods: Methods used to build different types of bridges are explained.
- Balanced cantilever method for box girder bridges:
-
Concept design: This covers the fundamental elements of bridge design, including:
- Span: The distance between supports.
- Length: The overall length of the bridge.
- Superstructure: The part of the bridge that carries the load (i.e., roadway, deck,etc.).
- Substructure: The supporting elements (i.e., piers, abutments, foundations, etc.).
- Bearings: Bridge bearings transfer loads from the superstructure to the substructure. They accommodate movement between these parts.
- Concrete barrier : A barrier constructed of concrete positioned to provide separation and safety along roadways.
- Noise wall: A barrier that mitigates noise pollution.
- Concrete deck: The load-bearing upper surface of a bridge.
Bridge components
- Abutments Components that support the ends of a bridge.
- Piers Components that support the bridge in the middle of the span.
- Pile Structural support typically installed underground.
- Pile caps Connect piles to form a platform which support other elements.
- Superstructure Part of the bridge that carries the traffic loads (roadway deck).
- Substructure Part of the bridge that carries and transfers loads to the ground support (piers, abutments, foundation piles).
Overview of bridge types
-
Suspension bridges:
- Golden Gate Bridge (1280m span, 1937)
- Akashi Kaikyo Bridge (1991m span,1998)
-
Cable-stayed bridges:
- Rusky Bridge (1104m span, 2012)
-
Arch bridges:
- Gladesville Bridge (300m span, 1964)
- Salgina Bridge (90m span, 1930)
- Box Girder bridges
- Plate Girder bridges
- Precast (Prestressed) Concrete bridges
- I-Girder bridges
- Concrete Trough Girder bridges
- Slab – concrete voided bridges
- Solid Slab bridges
Bridge Construction Methods
- Construction sequence using the balanced cantilever method: Construction steps and sequence to construct concrete segments are detailed.
- Box girder – concrete precast pretensioned Super T beams:
Bridge Substructure
- The substructure resists horizontal and vertical loads.
- Forces considered include bearing restraint, earth pressure, normal water flow, wind, earthquake, flood, differential bridge temperature loading, pedestrian loading, and traffic loading.
Pier columns and walls
- Pier columns and walls, according to AS 5100.5, must be designed as columns in case they are subject to in-plane vertical forces and horizontal forces perpendicular to the plane.
- Pile caps and spread footings may be designed as beams or using the strut and tie method.
- Construction procedures for driven and bored piles are described.
