1. Historical and societal influences
1. historical developments of civil structures
Beam Bridges Arch Bridges Suspension Bridges
2. engineering innovation in civil structures and their effect on people’s lives
Large buildings have allowed for apartments and businesses to work in a good environment. Bridges allowed people to cross water ways easily and quickly.
3. construction and processing materials used in civil structures over time
Timber Stone – Strong in compression, heavy Cast Iron Steel – Corrodes, strong in tension and compression Concrete
4. environmental implications from the use of materials in civil structures
Timer – Deforestation Stone – Needs to be quarried Steel – Pollutants from smelting Concrete
1. outline the history of technological change as applied to civil structures
2. investigate the construction processes and materials used in civil structures from a historical point of view
3. critically examine the impact of civil structures on society and the environment
2. Engineering mechanics and hydraulics
1. stress and strain
– shear stress
Shear stress occurs when you apply shear force. Eg. If a bolt is supporting a load perpendicular to the bolt of 10N, and it has a diameter of 10mm, what is the shear stress?
Shear Stress = kPaAreaShear
ForceShear127
23105

π
– engineering and working stress
Engineering stress is the stress a material is undergoing without taking into account the change in area.
– yield stress, proof stress, toughness, Young’s modulus, Hooke’s law, engineering applications
Yield stress occurs when there is an increase in strain without an increase in stress. Proof stress is the amount of stress necessary to bring a permanent strain in the material. Toughness is a measure of the ability of a material to absorb energy.
Hooke’s law is
E , it calculates Young’s modulus of elasticity.
– factor of safety
A factor of safety is how many times stronger the material or structure is than it needs to be.

– stress/strain diagram
2. truss analysis
– method of joints
This involves working around the truss, finding the forces in most of the members.
– method of sections
This involves cutting the truss so that you can calculate just the forces you want.
3. bending stress induced by point loads only
– concept of shear force and bending moment
– shear force and bending moment diagrams
Here is a beam (top), with the corresponding shear force diagram (middle), and bending moment diagram (bottom),
1. CIVIL STRUCUTRES ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
_____________________________________________________________________________________________________ HSC ENGINEERING STUDIES SYLLABUS NOTES 2007 – ANDREW HARVEY 4
– concept of neutral axis and outer fibre stress
The neutral axis has no stress in it. If the beam is bent the maximum stress occurs at the top and bottom faces of the beam.
– bending stress calculation (second moment of area given)
σ =My
I
σ = Bending Stress (Pa) M = Bending Moment (Nm-1)
y = depth of beam
2 (distance from neutral axis to outer surface) (m)
I = Second moment of area (m4) (Always given in the question) (if in mm4 use 𝑥4
then change units then x4)
4. uniformly distributed loads
The load is distributed along the whole beam, so there is no point on the beam with the most loading; it is equal the whole way along. A uniformly distributed load will result in a non-horizontal or vertical lines of shear force diagrams, and curves on bending moment diagrams.
5. crack theory
– crack formation and growth
Cracks form due to strain energy, which is internal stress. They also form by movement and vibration. They create areas of high stress, these areas of high stress create more cracks.

They grow because the further they penetrate the less force needed to continue the crack.
– failure due to cracking
As the crack penetrates further the material will crack completely and fail.
– repair and/or elimination of failure due to cracking
Cracks can be repaired by: filling the crack reinforcing with another material replacing it
Cracks can be eliminated for forming by:
High factor of safety (making the material much stronger than it needs to be) Using the best design. eg. adding webs and fillets
1. apply mathematical and/or graphical methods to solve problems related to the design of civil structures
2. evaluate the importance of the stress/strain diagram in understanding the properties of materials
3. calculate the bending stress on simply supported beams involving vertical point loads only
4. describe the effect of uniformly distributed loads on a simple beam, without calculations
5. examine how failure due to cracking can be repaired or eliminated
3. Engineering materials
1. testing of materials
– x-ray
X-ray testing will show any holes in the material, as if there are hole more X-rays will penetrate and this will show up on the photographic film.
– specialised testing of engineering materials and/or systems
Testing of materials can either be destructive or non-destructive. Each can be used for different purposes and situations.
2. ceramics
– structure and property relationship, applications
Ceramics are used because of their: Heat resistance Compressive strength Wear resistance Water resistance Non conductivity
– glass
Glass has low toughness and is brittle and weak in tension. Glass may be toughened to increase toughness. To toughen glass it is blasted with cold air on the surface, and then the outer layers are placed in compression.

– cement
3. composites
– timber
Plywood is a composite. It consists of layers of wood in alternating grain directions, with glue to bind it together.
– concrete (reinforced and prestressed)
Concrete is composed of sand, cement, aggregate and water.
Concrete macrostructure
Concrete is strong in compression, but weak in tension. To prevent the concrete from cracking when in tension, it is reinforced with steel rods or steel mesh. The steel rods or mesh are strong in tension and prevent the concrete from cracking. Prestressed concrete is when concrete is poured into rods which are in tension. Once the concrete has set the rods are released and they create compressive stress in the concrete.
Post-stressed is where the steel rods are stressed once the concrete has set.
If concrete is prefabricated, then it is cast separately then placed in its final position, it can be cast on and off site. This is contrasted to cast in situ, where the concrete is cast in its final resting place.
– asphalt
Asphalt is a composite of aggregate and bitumen. It is used mainly on roads.
– laminates
Laminates are materials with layers of other materials to change the properties. Laminated glass is used to create shatter resistant glass. It is produced by rolling two sheets of glass with a vinyl sheet in between them. Plywood is also a laminate as it consists of layers of wood glued together, this increases compressive strength and toughness.
rods held at one end, they are inside tubes, concrete is set then they are stressed in tension and anchored at the other end.

– geotextiles
Geotextiles are woven polymers or ceramic fibres. For example they are used to stop dirt from a construction site going into the drain.
4. corrosion
– corrosive environments
Corrosion is most likely to occur in materials that are subjected to water. Salt in the air or water will increase the effects of corrosion and make it happen faster,
– dry corrosion, wet corrosion, stress corrosion
Corrosion in the form of rust needs water. Corrosion occurs more at areas of high stress.
5. recyclability of materials
1. describe basic testing conducted on civil structures
2. examine the properties, uses and appropriateness of materials used in civil structures
3. make appropriate choices of materials and processes for use in civil structures
4. investigate the structure and property relationships in materials
5. explain the special properties produced by composite materials
6. experiment with simple pretensioned and post-tensioned structures
7. evaluate the significance of corrosion problems in civil structures
Concrete cancer is a form of corrosion problem which affects concrete. It occurs when the reinforcing steel rods corrode. When they corrode they expand, which causes the concrete to crack
8. describe methods used for recycling materials when civil structures are replaced

Static friction is a force that opposes the motion of two objects in contact.

Different materials in the same situation have different frictional forces. To account for this a coefficient of friction is given to different materials. Eg. Ice = 0.1 , rubber = 0.9.

Heated then cooled in air. Smaller equiaxed grains.
– hardening and tempering
Hardening results in the material becoming hard and brittle. Cannot harden low carbon steel. If toughness and hardness is required a steel is hardened then tempered. This results in slightly less hard materials but much greater toughness.
