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

WhatsApp Image 2021 07 25 at 15.32.37

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.

Canopy

Awning and Canopy 3

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

    Measurements should be converted into a CAD model

    Untitled 1 8

    • Well defined model is not required
    • Extracting data which is most important.

    Requirements:

    • Functional
    • Structural
    • Assembly
    • Maintenance
    • Environmental
    • Aesthetic
    • Safety
    • Reliability
    • Ergonomics

    Structural requirements:

    • To sustain the loads on awning from wind and self-weight and impact loads due to debris falling on awning.
    • To maintain stability of structure.

    Environmental requirements:

    To withstand environmental conditions of rain, heat and cold without deterioration in material property.

    Assembly requirements

    An assembly mechanism

    • to mount the frame of awning to the wall
    • Be able to dismantle the assembly if required

    Aesthetic requirements

    To maintain the look of the façade of the building and not look out of place..

    Concept development:

    Now that the requirements are understood. Next step is to generate concepts.

    How to Generate Concepts ?

    • Learning From Research and Gather Ideas
    • Brainstorm and Ideate
    • Synthesis of Ideas into concepts
    • Should meet requirements

    Awning -Concept

    Untitled 1 9

    Concept of mounting 1

    Untitled 1 10

    Awning is connected to the Wall by a Link with pin joints at either end

    Link is Aluminium channel

    Concept of mounting 2

    Untitled 1 11

    Awning is connected to the Wall rigidly through the Red frame on either side of Awning

    Bracket is Wooden

    Comparison of Concepts

    Concept 1 Concept 2
    Uses a link to connect the Awning to the wall Uses a structural bracket which connects the awning to the wall
    Uses Pin joints -temporary Uses Permanent joints
    Easier to dismantle Cannot be dismantled
    Lighter Heavier
    Additional brackets for mounting pins No additional brackets for pin mountings
    Inferior in Aesthetics Superior in Aesthetics
    Can take lesser loads Can take larger loads
    Cheaper Costlier

    Concept Selection

    • Concept 1 is inferior to concept 2 in aesthetics but superior in assembly requirements.
    • Concept 2 is stronger but that extra strength may not be required for the conditions.
    • Concept 1 is cheaper and light weight.

    Selecting a concept and the reasoning behind it ?

    • Ease of installation
    • Simple and light
    • Cheaper

    Although in this case Concept 1 has been considered superior but this might not be the case in all other instances of design

    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

    Untitled 1 14

    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

    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

    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

    Untitled 1 27

    Net load = 645.5 N

    Calculation for Compressive stress

    Untitled 1 28

    Hence design is safe in Compression

    Buckling

    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

    Untitled 1 29

    Calculation for buckling stability

    Untitled 1 30

    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.

    Untitled 1 31

    Untitled 1 32

    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.

    Untitled 1 33

    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

    Untitled 1 34

    Design of pin joint for strength

    Probable failure mode 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
