Awning and Canopy

Home \ Awning and Canopy

Both awnings and canopy offer you the chance to create a calm, protected outdoor space to enjoy, whatever the weather. Therefore, finding a professional contractor to install awnings and canopies for your beloved home is very important.

What is the Difference Between an Awning and a Canopy?

When purchasing an outdoor covering for their property, some people are unclear as to what the difference is between an awning and a canopy. First, let’s outline what’s the same about them.

Awnings and canopies are made from similar materials to each other, that are designed to be durable and weatherproof, but there are several material options to choose from to suit your individual needs.

Despite their similarities, awnings and canopies also have their differences too.


Awnings are sheets of material attached to the exterior of your home, fixed above a window or a door, and overhanging a porch, patio or walkway. They can offer shade and protection from the sun both outdoors and indoors, blocking the light from entering through windows, thus preventing artwork and furniture from fading, and also keeping it cool indoors.

Unlike canopies, awnings are a permanent fixture to the outside of your home and do not require any disassembly, though this does reduce flexibility. There are two main types of awnings: window awnings, and retractable awnings, which can fold away when they are not needed.

Because of their permanent state, awnings can act as a dry storage space for wet or muddy shoes and bikes; a preferable location over a hallway.

Awnings vary in length, but are are generally smaller than canopies. However, it’s important to choose the right size for your requirements. If you require a space to hold parties and BBQs, then a bigger awning may be better, or possibly a canopy.

A range of colours, patterns and styles are available to suit the architecture of any house. Remember that awnings are a permanent structure and therefore it’s advisable to choose some that complement the current style and decor of your garden, taking into account your garden furniture and window dressings.

Awning are also widely used as a fixture for motorhomes and campervans, offering a relaxed dining area.


Canopies are often large, free-standing coverings, used to provide shade and protection from the elements for a seated, outside area. They are made from a large canvas of a durable fabric, strung over a metal frame and between supporting posts. However, they can sometimes be placed directly next to your windows and doors, which is perhaps why people sometimes confuse them with awnings.

Canopies tend to be bigger than awnings, making them more suitable for gatherings, parties and BBQs.

They are portable, and are easily disassembled and stored away when not in use. Because they are transportable, they are also ideal for outdoor events, festivals or trips to the park.

Because they are not anchored in one place, canopies offer more flexibility than awnings, allowing you to choose exactly where you want to set up your shaded space.

Usage and Benefits of Awning and Canopy

Awning and Canopy have a relatively fixed usage. It is commonly used for:

  • preventing harsh light and shadow from entering the house
  • keeping the temperature of the house low
  • protecting furniture from sun damage
  • keeping a pouch cool and comfortable

Converting the design problem to an Engineering problem

Formulating the engineering problem


  • Get the reaction forces
  • Use reaction forces to calculate stress in the member

Arriving at the Design load

  • Wind loads
  • Self weight

Wind Load direction

Wind velocity

Wind pressure calculations

150 km / h =42 m / s

Generic formula for wind pressure , P = 0.613 V^2

Source : Wikihow

Considering the area of application faces a year round probability of storms then the maximum velocity of wind

For a sever storm is maximum 150 km/h

Calculated Pressure (N/m^2) –

= 0.613 * 42^2

= 1081 N/m^2

Calculate the Load from pressure

Projected area of the Awning is 1 metre X 0.7 metre = 0.7 m^2

Load acting = Pressure X Area

Load = 1081 * 0.7 = 756.7 N or 76 kg

Self Weight calculation

Self weight , Sheet = 11 kg

Frame = 10 kg

Total Design load = Wind load + Self weight load

= 76 +11+10 = 100 kg

Assumed :

Although the Weight will act vertically downwards, the Load due to self weight is a fraction of the wind load.

Considering Overload factor as 1.5

Cause of Overloads?

  • Debris falling onto the awning
  • Extreme gale force winds
  • Material variations
  • Dimensional variations

Load to be considered = 150 kg = 1500 N

+ (731.7)(487.7-337) + (164.9)(109.8-76) = 0

-(Rva)(487.7) -(Rha)(109.8) +115840 = 0  3

Finding Fce

  1. Rha–(164.9) +(0.857*Fce)=0  >>  Rha= (164.9) -(0.857*Fce)
  2. va–(731.7)+(0.515*Fce)=0  >>  Rva= (731.7) -(0.515*Fce)
  3. -(Rva)(487.7) -(Rha)(109.8 +115840 = 0

Substituting Rhaand Rvain equation 3 to find Fce

-((731.7 -0.515*Fce)(487.7)) –((164.9 -0.857*Fce)(109.8)) +115840 = 0

-356850 + 251.2 Fce –18106 + 94.1Fce + 115840 = 0

-222904 + 345.3 Fce = 0

Fce = 222904 / 345.3

Fce = 645.5 N

Finding Rva, Rha

Rha= (164.9) -(0.857 * 645.5)     Rha= -388.29 N     (opposite direction to what was assumed)

Rva= (731.7) -(0.515 * 645.5     Rva= 399.3 N

Final FBD of Link AD

Link AD

Finding Rhe, Rce

Rve= 332.2 N

Rhe= 553.2

Axial Force on link

From the reactions already calculated find the component of force in the axis of the link

This will be an input to calculate the strength of the link.

Calculation for Compression loading

Fce = 645.5 N

Next step is to calculate the Compressive stress and Buckling stability and design the section of the link and see if it exceeds the Tensile strength of the material

Net load = 645.5 N

Calculation for Compressive stress

Hence design is safe in Compression


What needs to be calculated?

Whether the load which is acting on the link exceed the Critical load which would buckle the link?

Formula :

Critical Load =?2??/?2

E –Youngs modulus

I –Moment of Inertia of section

L –Length of Column

Calculation for buckling stability

Inputs :

1.E -Elastic modulus –Aluminium -69 GPa

2.I –Moment of Inertia – I = 1.232e-008 m^4

3.L –Length of Link –0.57 m

Calculating using formula

???= 3.142∗69∗109∗1.232∗10−8/0.572 = 25 kN

Critical Load is much larger than 645.5 N , hence the link is safe from Buckling.

The Link is Strong in buckling and compression with very large margins.

This means that the section of the link can be reduced to reduce weight and maintain strength and stability.

Re-calculating Compressive stress

Stress = Load / Area

Stress = 645.5 N / 6.4e-005 m^2

Compressive Stress = 10 Mpa

Re-calculating Buckling critical Load

???= 3.142∗69∗109∗7.253∗10−10 / 0.572

???= 1518 N

Safety factor = ???/ Load = 1518/654.4 = 2.3

Design of Pin -Shearing vs Bending

Mode of failure of joint:

  • Shearing off ,
  • bending

Which is more likely to happen?

In this case it would be shearing of as the length of the pin is not long

Design of pin joint for strength

Probable failure mode of Pin :

Failure due to Shear failure

The Pin has to be designed keeping in mind this Shearing action

Force acting on the Pin

Stress area of pin.

Shear Stress calculation

Stress = Force / Area

Stress = Force acting on the Pin / Shear Area

The Pin diameter is 6 mm

Area = 28.26 mm^2

Force = 654.5

Stress = 654.5 / 28.26 = 25 N/mm^2 or MPa

Steel Shear strength = 240 N/mm^2 (MPa)

Design is safe in Pin Shear

FEA Analysis of Awning

This analysis can be done by FEA analysis of the Awning frame with shown boundary conditions.

Setting up the Analysis

Material –Steel with Yield strength 240 Mpa

Boundary conditions

Load case

Loading : 1500 N

Area : Across the top surface of the full frame



Max Von mises Stress at centre = 100 MPa

Well within the Acceptable limit of yield strength of generic steel



Max Displacement at centre –2.2 mm

Rva= (731.7) -(Fce.cosθ )     B

Rewriting Equation 3 from earlier section

-(Rva)(487.7) -(Rha)(109.8) +115840 = 0     3

Substituting A and B in equation 3

-((731.7 -Fce.cosθ )(487.7)) –((164.9 -Fce.sinθ)(109.8)) +115840 = 0

-(356850-487.7. Fce.cosθ) –(18106 -Fce.sinθ.109.8) +115840 = 0

-259116+487.7. Fce.cosθ+Fce.sinθ.109.8 = 0

487.7. Fce.cosθ+Fce.sinθ.109.8 = 259116

Fce(487.7.cosθ+109.8.sinθ)= 259116

Fce= 259116 / ((487.7.cosθ+109.8.sinθ))

Shear Stress on Pin = Fce/ 28.26

Now only with input as angle , all the above can be calculated

Buckling critical load = 518

L = 0.975 m long

Not desirable , Link is too long

At θ= 70 deg

Fce= 750

Buckling critical load = 1800

L = 0.519 m long

Shear Stress on Pin = Fce/ 28.26

= 26 MPa

Desirable , Link is short.

At θ= 90 deg

Fce= 1355.3

Buckling critical load = 2074.5

L = 0.487 m long

Shear Stress on Pin = Fce/ 28.26
