Benefits of Timber Roof Trusses in Building Construction

Benefits Of Timber Roof Trusses In Building Construction


Wood or Timber roof trusses are widely used in the USA, Canada, and other countries because of its advantages over other trusses, as it offers great flexibility in plan layout.

Be it a residential, industrial, commercial, or an institutional building, roof of any kind of structure is the most important component of a building as it protects its occupants from the external elements of roof trusses in building construction.

It is also the largest and the most expensive structural component of a building so investing some thoughts and know-how in the design and planning of a roof to create an aesthetically pleasing and sound structure that can safely carry the induced loading, while offering acceptable longevity and an attractive appearance for the lifespan of the building is nothing but logical.

There are basically two kinds of material that are prevalent around the globe for the fabrication of trusses: Steel and Wood. While steel trusses have the advantages of ease of handling and erection, there are also some huge drawbacks like high material and maintenance cost and low thermal resistance. Timber/Wood trusses on the other hand have a long list of advantages and a shorter list of disadvantages.

The high strength-to-weight ratios of timber trusses permit long spans, offer greater flexibility in floor plan layout. They can be molded into almost any shape and size restricted only by manufacturing capabilities and handling considerations.

Today, most of the house-roofs in the USA, Canada, and Australia are framed with timber trusses and increasingly, timber trusses are being used in residential and commercial applications. They are gaining acceptance around the world and are being used widely in Europe and Japan.

Incorporation of steel (truss connector plates) in the timber trusses further revolutionized the whole industry. Timber frames with wide-spanning trusses or softer timbers may require steel for structural support and it can be incorporated either visibly or invisibly into a frame depending upon a person’s aesthetic considerations.

A truss connector plate or a Gusset plate is a thick galvanized steel sheet that is used for connections at the joints; it is fastened to a beam with bolts. Plates can help support heavier structural loads than timber alone, which allows for wide-spanned truss designs. They can also be used to provide shear resistance and other types of force.

Benefits of Timber Roof Trusses

When the advantages of timber roof trusses in building construction are considered, it is not astonishing that their use is increasing throughout the world.

1) Flexibility and Versatility

Timber roof trusses are very versatile and compatible with other structural products. They can be linked to other trusses, or amalgamated with other components, such as glulam and steel beams.

The Long spans without intermediate supports create large open spaces that architects and designers can use that with complete freedom. Moreover, the partitions can be moved without compromising the structural integrity of the building.

2) Eco-friendly

Timber also acts as a sustainable material in modern construction technology. Timber exhales in Co2, grabs the carbon for itself, and releases the Oxygen into the environment. It doesn’t stop here! Fifty percent of Timber by weight is carbon stashed safely away. Compared to other buildings, timber consumes much lesser energy to process and minimize air and water pollution. Furthermore, Timber is the only renewable construction material and helps define sustainable development very strongly.

3) Economy

In most cases, timber roof trusses can be installed without the use of heavy machinery. They are light in weight and can be easily handled and lifted into place. Moreover, the time consumed in developing a timber frame is amazingly low thus condensing a project’s life-cycle.

Timber trusses do not contribute to waste generated at the site and make clean-up work less costly. Pilferage is also reduced since the timber roof trusses generally cannot be used in the other projects.

4) Durability and Strength

Timber trusses eliminate the majority of the on-site framing problems. Accurate fabrication and constant quality control assure trusses are uniform in size and shape and provide required structural integrity to a building. Timber trusses can also be used in concrete formwork, scaffolding, and falsework for industrial projects.

5) Energy Efficient

Timber trusses are energy efficient. They have excellent thermal properties, especially when compared with other framing materials such as steel. They create large cavities that are easy to insulate and hence are an excellent insulator.

6) Aesthetical Freedom

Timber trusses have almost unlimited variety thus providing the user with a great leeway to experiment with the aesthetic features of a building. Many restaurant chains choose to expose their corporate identity in the roof design of their buildings.

What Are The Different Types Of Roofs?

What Are The Different Types Of Roofs? The roof is the uppermost portion of the building which protects the building from rain, wind, and sun. Various types of roofs used may be divided broadly into three types: 1. Flat roofs 2. Pitched roofs 3. Shells and folded plates. Flat roofs are used in plains where rainfall is less and climate is moderate. Pitched roofs are  preferred wherever rainfall is more. Shells and folded plate roofs are used to cover large  column-free areas required for auditoriums, factories, etc. Brief description of these roofs is  presented below: 1. Flat Roofs These roofs are nearly flat. However slight slope (not more than 10°) is given to  drain out the rainwater. All types of upper-story floors can serve as flat roofs. Many times  top of these roofs are treated with waterproofing materials-like mixing waterproofing  chemicals in concrete, providing Coba concrete. With the advent of reliable waterproofing  techniques, such roofs are constructed e

The Common Rafter and Purlin Roof

The Common Rafter and Purlin Roof As a civil engineer or roof contractor, you should aware of the construction of a roof and trussed roofs also types of roof construction in the industry. So, here our new article about roof rafter and purlin roof related to roof construction. The structure is most commonly used where there is a gable at both ends of the roof and is frequently to be found on terraced houses, as indicated in the below picture. This simple form of roof is illustrated in below picture. Its construction has been included here because of the now very common refurbishment of such houses. The wall plates are often simply bedded on mortar on either the inner skin of a cavity wall or, as is often the case with older terraced houses, on the inside edge of a solid 9 in. brick wall. Wall plates should be half lapped where they meet, and should not be less than 75 mm wide and 50 mm thick. They should be treated with preservative. Below picture shows typical plate co

The Coupled Roof, Ceilings And Trusses

The Coupled Roof, Ceilings and Trusses M oving off from early roof forms that provided each wall and roof in one unit, succeeding development showed a real roof designed on masonry or timber walls. the only type of roof was a coupled roof, consisting of 2 lengths of timber bearing against one another at the highest and resting on a plate at their feet. The timbers, known as couples, were pegged along at the highest with timber dowels and were equally pegged or spiked to the plate. The term ‘couple’ was used until the fifteenth century once the terms ‘spar’ or ‘rafter’ began to be used. The term rafter in fact continues to be wont to describe the piece of timber during a roof spanning from the ridge to the place. paced regarding four hundred millimeters apart tied solely by horizontal binders and tile battens. the easy couple was adequate for tiny span dwellings and steep pitches, however the outward poke force at the feet of the rafters caused stability issues with the walls
