CIVIL ENGINEERING
Abutments - answer-connect the bridge to the
ground
All areas of civil engineering must have a good
understanding of ___ - answer-structures
All structural materials have ____ such as - answer--advantages and disadvantages based on
their properties.
Ex; concrete has high strength when in compression,
but has low tensile strength
Ex; Steel has high compression and tensile strength
but weighs more
Arch bridges (3) - answer-- Structural members always in compression
- Can distribute load to abutments
- Often have to be massive to withstand force
impractical in areas with loose soil or little rock
Basic components of Bridges (3) - answer-Piers
Abutments
Roadway
Beams (2) - answer-- transmit loads to columns
- Used to resist bending
Bending force - answer-force causing sagging
Braces (3) - answer-- Used to provide structural stability
- Often form triangles between beams and columns
- Provide resistance from forces
Calculate reactions and internal forces - answer-Reactions are applied in the opposite direction
of the
load
, CIVIL ENGINEERING
Cantilever bridges (4) - answer-- Use trusses extending out in both directions from support
beams
- Two cantilevers and one suspended span
- Truss framework often used on side of bridge
- Load is transmitted to the center
Central core of skyscraper (4) - answer-- Usually a reinforced concrete shaft at the center of the
building
- Structural frame is attached to the core to help stability
- Contains elevator shafts and mechanical systems
- Helps resist wind and earthquakes
Civil engineers often manage construction (2) - answer-- Substructure consisting of piers and
footings is constructed first
- Central core and structural frame is build
Civil engineers work in teams (3) - answer-- Structural engineers
- Architectural engineers
- Land surveyors
Columns (2) - answer-- Vertical structural members
- Transmit load from above
Combination bridges (2) - answer-- Sometimes a single type does not meet needs
- Combination of two or more types might be best solution
Compression - answer-crushing, pressing force
Construction engineering - answer-Manage, coordinate and organize the flow of materials and
workers in order to stay on budget and on time
Dynamic loads - answer-A sudden impact on the structure
Each structure must meet specific constraints (4) - answer-- Length of span
- Type of foundation
- Environment
