timber design

Timber design is a field of engineering that deals with the strength and behaviour of timber structures. It also includes the determination of member sizes, connection details, and the overall stability of the structure. Moreover, timber design is often used in the renovation or repair of older buildings, as it can be used to replace an existing beam without affecting the surrounding structure.

Timber is an important structural material that plays a vital role in the design of buildings and structures. Timber must be designed and calculated carefully to ensure that it meets all requirements, while also ensuring that the finished structure is safe and sustainable.

Timber has been used in construction for thousands of years, and its popularity is increasing due to its environmental benefits. Timber construction is efficient, and it can be used to create a variety of different structures.

We can help you if you require a loft conversion design or simply need to know the size of floor joists or rafters required for your extension or new build property. SECalcs’ main goal is to make timber design as simple and easy for our clients as possible.

Timber Floor Joist / Roof Rafter Design

Floor joists and roof rafters are required for the majority of extensions and alterations to existing and new properties. Load span tables can be used to provide designs; however, this method can result in excessive floor joist or roof rafter specifications or may not accommodate all loads applied. SECalcs strives to provide the most cost-effective solution by creating customed designs for your project.

Where a regular timber beam would be insufficient, a flitch beam is usually required. Flitch Beams are made from both timber and a steel plate. A steel plate is sandwiched between the layers of timber, and the entire system is held together by bolts. Because of the combination of the lightness of the timber and the strength of the steel plate, the beam can span much further than a standard timber beam. Flitch beam can be used in a variety of applications, including floor joists and roof trusses. Flitch beams are strong and durable, making them ideal for use in both commercial and residential structures.

Loft Conversion Design

A loft conversion is a great way to add extra living space to your home. But before you start planning your new space, you need to make sure your loft is structurally sound.

That means having a professional assess the condition of your existing roof and floor and doing the necessary structural calculations. Timber is typically weaker than steel, so it’s important to make sure the structure can support the additional weight of a converted loft.

Here at SECalcs, we aim to provide the most cost-effective solution by creating tailored designs for your project.

King Post Truss Design

A timber King post truss is a common design used for decorative roof trusses with vaulted ceiling. The king post truss is made up of a single vertical member called the king post that supports the ridge and two struts that support the purlins. The arrangement of the king post and the two struts is frequently altered to accommodate decorative designs. The design is simple, yet effective and has been used in the UK for centuries. Glulam, or glued laminated timber, is often used for the king post as it is strong and durable.

Traditional Cut Roof Design

If you want to make an extension or a new building and want to include an additional area for a future loft conversion or simply want to cut through your roof, please contact us and our Engineers will be happy to help.

Screw/Bolt Connection Design

Whether a King Post is installed, or a traditional cut roof is built, a number of timber joists/rafters will most likely need to be connected together. This could be for cosmetic or structural reasons, such as preventing roof spread. Please get in touch with us, and our engineers will be glad to assist.

What is a structural engineer?

A structural engineer is someone who is responsible for the design of a structure, such as a building. They make sure that the calculations they provide will be suitable for building regulation approval. In some cases, they may also be responsible for choosing the building material.

Structural engineers are highly trained and skilled professionals. They must have a good understanding of physics and mathematics, as well as knowledge of construction methods. It is important that they are able to communicate effectively with other members of the construction team.

The role of a structural engineer is vital in ensuring that a structure is safe and fit for purpose. They play an important part in the design process and their work can have a significant impact on the overall cost and time taken to build a project.

We believe that our experience and expertise in the field of timber engineering is second to none, and we are confident that we can provide our clients with the best possible solution for their needs.
