Mass Timber Buildings - An Innovative Concept for a Better Building Construction Tomorrow Created By:

We are in the era of the 21st century, where technology has advanced a lot. No matter what so ever is the industry, each one of them has with all open arms accepted the latest services and its concept. If talking the same is with regards to the construction of buildings too. So, today in this Presentation we would be sharing some of the reasons where the innovative concept of constructing buildings is done with the help of timber or wood. We all know that wood or timber is the material that is renewable as well as eco-friendly too. The concept of developing Mass Timber buildings was very much used and adopted in the North American countries, and it was because of the weather condition that is cold.

We all know that wood or timber is the material that is renewable as well as eco-friendly too. The concept of developing Mass Timber buildings was very much used and adopted in the North American countries, and it was because of the weather condition that is cold. Now when speaking about the mass timber, there are two types of framing methods in wood and that also is the region of North America. The most common method that is taken into consideration is for residential construction which is actually termed as light-frame construction. Now for using this process the method used here is balloon-framing or platform-framing. When thinking economically the building material that is used as a standard dimensional lumber has become one of the dominant building materials that is very light in frame. For all the non-residential construction the method that is taken into consideration is heavy-timber wood materials.
Types of Mass Timber Services: 1) Glue-laminated Timber (glulam) •
It is the type of discrete wood laminations, that is categorically selected and positioned at the base of the construction area and it is totally depending upon their performance and its characteristics, and then this is at the later stage bonded together with the durable and moisture-resistant adhesives.
•
The horizontal application of glulam is considered for using in beams whereas the vertical one is used for columns. It has a great amount of strength and the firmness properties is for pound and pound. Also, one of the biggest facts is that glulam is way much stronger than steel.
2)Parallel Strand Lumber (PSL) •
The manufacturing of PSL is from the veneer material that is then clipped into long strands for the parallel formation. With the help of adhesive it is bonded together so as to form finished structural sections. PSL is indeed best and well suited and used for beams and columns in post-and-beam construction. Taking it further for beams, headers and lintels the method used is in light-framing. PSL is the type where it is suited best where the appearance matters and that it should look attractive. Also, for structural applications the appearance is not at all a factor.
3)Laminated Veneer Lumber (LVL) •
•
LVL is the material that is made up of dried softwood veneers. This is then bonded together with the help of adhesives and post that these veneers are set parallel to the long direction. Since LVL is having a high ratio of strengthto-weight it is best selected as a replacement option for dimension lumber or glulam. This entire process is connected with heavy materials like beams, headers, headers, and lintels. The use of LVL is also considered for prefabricated wood in I-joists and truss chords.
4) Laminated Strand Lumber (LSL) •
The name itself communicates a lot about its services. Let us first understand how it has been made. LSL is basically made by the alignment of thin chips to the strands of the wood which are then glued under a heavy pressure. The wood grain of the strands is then originated parallel to the range of the member and then at the later the wood member is being machined for having a consistent finished size. Here LSL is having a lower amount of strength and rigidness properties as that of LVL.
5) Oriented Strand Lumber (OSL) •
This is very much similar to the making of LSL. But one small difference and that is that OSL is made from the flaked wood strands. Here the panels are made from tapered strands of fibre oriented and that is also based on its length and requirement. Post then they are arranged into layers at the right angles to one another. Here this process is laid and bonded together with the adhesives that are waterproof as well as heat-cured.
6) Cross-laminated Timber (CLT) •
•
The creation of engineered wood panels, or building design, is only CLT that is actually prepared with multiple layers of lumber and that too with the aim of having them set at the right angle which is equal to one another. The lumber dimensions here are having layers of three, five, or seven.At the later stage having stability, rigidity, and strength it is then glued to form a particular panel.
As CLT has a good stability over structural properties and dimensional process, the use of mass timber product is well suited to be used in floors, walls, and roof that are used in the tall and mid-rise wood building construction. The wall panels here are being exposed or rather to say left exposed in the interior surface and for this the core reason is to give it an additional attribute of aesthetic.The panels that are created then can be used as prefabricated components that can speed up the overall process and practice of the construction and can also allow it for the use at the off-site construction.
