Types of Trusses Used in House Construction
Trusses are a type of structural framework used in house construction to support the weight of the roof and provide stability to the overall structure. They are pre-fabricated and made up of interconnected triangles, which give them their strength and rigidity. There are several types of trusses used in house construction, each with their own set of unique features and advantages.
- King Post Truss: This is the simplest and most commonly used type of truss in house construction. It has a central vertical post, two angled rafters, and a horizontal tie beam connecting the base of the rafters. It is a cost-effective and straightforward design that can be used for various roof spans, making it a popular choice for residential homes.
- Queen Post Truss: This truss design features two vertical posts, two angled rafters, and two horizontal tie beams. It is similar to the king post truss but provides more support, making it ideal for roofs with longer spans. It is also commonly used in home styles with a more traditional or ornate aesthetic.
- Scissor Truss: This truss design features two angled rafters that cross over each other at the peak of the roof, forming an X shape. It provides more headroom and creates a vaulted ceiling effect, making it a popular choice for homes with a modern or open-concept design. It is also commonly used in larger homes, as it can support longer roof spans.
Other types of trusses used in house construction include flat truss, fan truss, and bowstring truss. These designs are less commonly used, but they provide unique advantages for specific types of homes and roof structures.
When constructing a house with trusses, it is essential to consider the load-bearing walls. Trusses provide support for the roof, but they do not provide support for the rest of the house. Load-bearing walls are necessary to distribute the weight of the house down to the foundation. In houses with trusses, load-bearing walls are typically located on the exterior perimeter and the interior centerline of the house.
| Truss Type | Features | Advantages |
|---|---|---|
| King Post | Central vertical post, 2 angled rafters, horizontal tie beam | Cost-effective, straightforward design, can be used for various roof spans |
| Queen Post | 2 vertical posts, 2 angled rafters, 2 horizontal tie beams | Provides more support than king post truss, ideal for longer roof spans, commonly used in traditional or ornate homes |
| Scissor | 2 angled rafters that cross over each other at the peak of the roof, forming an X shape | Provides more headroom, creates a vaulted ceiling effect, ideal for modern or open-concept homes, can support longer roof spans |
Overall, each type of truss used in house construction has its own unique set of features and advantages. When determining which type of truss to use, it is essential to consider the size and scope of the project and the specific needs of the home being constructed. By properly selecting and installing trusses and load-bearing walls, homeowners can ensure that their houses are structurally sound and safe for years to come.
Benefits of Using Trusses in Construction
Load Bearing Walls in Houses with Trusses: Do They Exist?
One common misconception about houses built with trusses is that they do not have any load-bearing walls. Trusses can span longer distances than traditional framing, which means that they can carry more weight without the need for load-bearing walls. However, this does not mean that load-bearing walls do not exist in houses with trusses.
In fact, most houses with trusses do have load-bearing walls, but their placement and purpose may differ from traditional framing. Load-bearing walls in houses with trusses typically serve to transfer weight from the roof and upper floors to the foundation. The exact placement and number of load-bearing walls will depend on the design of the house, the size of the trusses, and other factors.
The Benefits of Building with Trusses
- Cost-effective: Trusses are pre-fabricated in a factory, which means that they can be produced quickly and efficiently. This can help reduce labor costs and save time during the construction process.

Characteristics of Load Bearing Walls
Load bearing walls are essential components of a building’s structure, as they are responsible for supporting the weight of the floors, roof, and other levels of the structure. Here are some characteristics of load bearing walls:
- They are typically thicker than non-load bearing walls, with a width of at least 8 inches.
- They are made of durable materials such as concrete, brick, or stone.
- They are strategically located to support the weight of a structure by transferring the load to the foundation.
Load Bearing Walls in Houses with Trusses
If a house has trusses, it means that the roof structure is supported by a series of triangulated structures made of wood or steel. These trusses are designed to distribute the weight of the roof to the load bearing walls and frame of the house. Therefore, load bearing walls are still present in houses with trusses, and their role remains the same in distributing the weight of the roof to the foundation.
Identifying Load Bearing Walls
It is important to identify load bearing walls to ensure that modifications made to the structure do not compromise its stability. Here are some ways to identify load bearing walls:
- Check the blueprint or architectural plans of the house to identify which walls are load bearing.
- Look for walls that run parallel to the roofline or perpendicular to the floor joists.
- Check the basement or crawl space to see which walls continue through to the foundation.
Removing Load Bearing Walls
Removing a load bearing wall without installing a suitable support beam or column can result in the collapse of the structure. Therefore, it is crucial to seek the help of a structural engineer or a licensed contractor before making any changes to the load bearing walls of a house. A temporary support system must be installed before removing the load-bearing wall and a new support beam must be installed in its place.
| Structural Element | Maximum Span Without Support |
|---|---|
| 2×4 Wood Studs | 8 feet |
| 2×6 Wood Studs | 10 feet |
| 2×8 Wood Studs | 12 feet |
| 2×10 Wood Studs | 14 feet |
| 2×12 Wood Studs | 16 feet |
The table above shows the maximum span without support for common wood studs. If a wall exceeds these maximum spans, it is likely a load bearing wall that cannot be removed without proper support.
How to Identify Load Bearing Walls in a House
Load bearing walls are essential elements in the structure of a house. They serve as support and distribute the weight of the building over the foundation. Identifying load bearing walls in a house is crucial when planning to make any structural changes.

- Consult a Professional: The safest way to identify load bearing walls is to consult a structural engineer or contractor. They have the expertise and the necessary tools to evaluate the structure of a house and determine which walls are load bearing.
- Blueprints and Building Plans: If the house has blueprints or building plans, they can provide insights on the structure and identify load bearing walls. Check for notes or symbols that indicate load bearing walls.
- Observe the Basement: Start from the basement or crawl space. Load bearing walls typically run perpendicular to the floor joists and support the main beams that span the foundation walls. Look for walls that align with the beams and that extend uninterrupted to the upper floors.
- Check the Attic: Observe the attic or the top floor of the house. Load bearing walls generally support the roof trusses or rafters and run parallel to them. Look for walls that align with the trusses or rafters and extend uninterruptedly to the foundation.
- Tap-test: If you are unsure about a wall’s load-bearing capacity, you can perform a tap-test. Lightly tap on the wall with a hammer or a rubber mallet and listen to the sound. Load-bearing walls sound solid and dense, while non-load-bearing walls sound hollow and echoey.
It is important to note that some walls may have a combination of load-bearing and non-load-bearing components. For example, a wall that supports a floor or a roof but has an opening or a doorway is considered a partial load bearing wall. In such cases, consulting a professional is recommended.
| Load-bearing wall features | Non-load-bearing wall features |
|---|---|
| Supports the weight of the roof, floors, or beams | Does not support any structural weight |
| Extends uninterruptedly from the foundation to the roof | May have openings or cutouts |
| Runs perpendicular to the floor joists or the roof trusses | May run parallel to the joists or trusses |
| Sounds solid and dense when tapped on | Sounds hollow or echoey when tapped on |
