Floor Truss Design: Floor Truss Span Chart
Floor trusses are engineered structures designed to support the weight of a floor and its occupants. They are typically made of wood or metal and are designed to span long distances without the need for additional support.
Basic Principles of Floor Truss Design
The basic principles of floor truss design are based on the principles of structural mechanics. Trusses are designed to transfer loads from the floor to the supporting walls or columns. The loads are transferred through a system of chords, webs, and diagonals.
The chords are the top and bottom members of the truss. The webs are the diagonal members that connect the chords. The diagonals are designed to resist shear forces.
Floor truss span charts provide essential data for designing and constructing sturdy floor systems. If you’re planning a project involving floor trusses, be sure to consult these charts for accurate span information.

Returning to the topic of floor truss span charts, remember that they serve as a valuable resource for ensuring structural integrity and optimal performance in your construction projects.
Components of a Floor Truss
- Top Chord:The top chord is the upper horizontal member of the truss. It is typically made of a single piece of lumber or a built-up member.
- Bottom Chord:The bottom chord is the lower horizontal member of the truss. It is typically made of a single piece of lumber or a built-up member.
- Webs:The webs are the diagonal members that connect the top and bottom chords. They are typically made of a single piece of lumber or a built-up member.
- Diagonals:The diagonals are the members that connect the webs to the chords. They are typically made of a single piece of lumber or a built-up member.
- Gusset Plates:Gusset plates are metal plates that connect the webs to the chords. They are typically made of steel or aluminum.
Factors Affecting the Design of a Floor Truss
The design of a floor truss is affected by a number of factors, including:
- Span:The span of the truss is the distance between the supporting walls or columns.
- Load:The load on the truss is the weight of the floor and its occupants.
- Material:The material used to construct the truss can affect its strength and weight.
- Code Requirements:The design of the truss must meet the requirements of the local building code.
Floor Truss Span Charts
Floor truss span charts provide valuable information for selecting the appropriate truss for a specific application. These charts list the typical span ranges for different types of floor trusses and consider factors such as the type of lumber used, the spacing of the trusses, and the live and dead loads that the truss will be subjected to.
Factors Affecting Floor Truss Span
- Type of lumber:The strength of the lumber used in the truss will affect its span.
- Spacing of the trusses:The distance between the trusses will affect the load-bearing capacity of the floor system.
- Live and dead loads:The live load is the weight of people, furniture, and other items that will be placed on the floor. The dead load is the weight of the floor system itself, including the trusses, sheathing, and insulation.
Using a Floor Truss Span Chart
To use a floor truss span chart, first determine the type of lumber that will be used for the trusses and the spacing of the trusses. Then, find the corresponding span range for the desired live and dead loads. The span range will typically be given in feet and inches.
For example, if you are using 2×10 lumber spaced 24 inches on center and the live and dead loads are 50 pounds per square foot, the span range would be 12 feet to 16 feet.
To calculate the appropriate size of a floor truss, refer to a floor truss span chart for guidance. These charts provide valuable information on the maximum span lengths for different truss depths and loads.

Floor Truss Installation
Installing floor trusses is a crucial step in the construction process. Proper installation ensures the structural integrity and safety of your building. Here’s a comprehensive guide to help you through the process:
Before beginning, gather the necessary tools and materials, including safety gear, a level, a measuring tape, and a truss hoist. Ensure the work area is clear and secure.
Planning and Preparation
Begin by reviewing the truss layout and determining the location of each truss. Mark the positions on the foundation or subfloor using a chalk line or string. Position the trusses carefully, ensuring they align with the marked lines.
Lifting and Setting
Use a truss hoist or other lifting equipment to raise each truss into place. Guide the truss carefully onto the support beams or walls. Ensure the truss is level and plumb before securing it.
Securing the Trusses
Secure the trusses to the support beams or walls using truss clips, nails, or bolts. Check the manufacturer’s specifications for the recommended fastening methods.
Tips and Tricks
- Use a level to ensure the trusses are level and plumb.
- Double-check the truss layout and positions before lifting them into place.
- Work with a partner or crew to lift and set the trusses safely.
Safety Precautions, Floor truss span chart
- Wear appropriate safety gear, including a hard hat, safety glasses, and gloves.
- Never lift trusses without proper lifting equipment.
- Be aware of your surroundings and ensure the work area is clear of obstacles.
Floor Truss Load Capacity
Determining the load capacity of a floor truss is essential for ensuring the structural integrity and safety of a building. The load capacity refers to the maximum amount of weight that a truss can support without compromising its structural integrity.
To determine the load capacity of a floor truss, several factors must be considered, including the type of truss, the span length, the spacing between the trusses, and the materials used in its construction. Different types of loads can be applied to a floor truss, including live loads (occupants, furniture, and movable objects), dead loads (permanent fixtures and structural components), and environmental loads (wind and snow).
Types of Loads
- Live Loads:These are the loads imposed on the truss by occupants, furniture, and other movable objects. Live loads are typically estimated based on the intended use of the space and building codes.
- Dead Loads:These are the permanent loads that are constantly present on the truss, such as the weight of the truss itself, roofing materials, and any fixed fixtures or equipment.
- Environmental Loads:These are the loads imposed on the truss due to external factors such as wind and snow. Environmental loads are determined based on the geographic location and local building codes.
Floor Truss Inspection and Maintenance
To ensure the safety and longevity of floor trusses, regular inspections and maintenance are essential. These inspections should be performed by qualified professionals and should include a thorough examination of all truss components, connections, and supports.
Inspection Types
There are several types of inspections that can be performed on floor trusses:
- Visual Inspection:A visual inspection involves examining the truss for any visible signs of damage, such as cracks, splits, or loose connections.
- Load Testing:Load testing involves applying a controlled load to the truss to assess its strength and integrity.
- Destructive Testing:Destructive testing involves applying a load to the truss until it fails, which is typically only done in research or development settings.
Inspection Procedures
When performing a visual inspection, it is important to pay attention to the following areas:
- Connections:Check for any loose, damaged, or missing bolts, nails, or other connectors.
- Members:Inspect the truss members for any cracks, splits, or other signs of damage.
- Supports:Ensure that the truss is properly supported and that there is no settlement or movement of the supports.
Maintenance Tasks
In addition to regular inspections, there are several maintenance tasks that can be performed to extend the lifespan of floor trusses:
- Keep the truss clean:Remove any debris or dirt that may accumulate on the truss.
- Protect the truss from moisture:Avoid exposing the truss to excessive moisture, as this can lead to corrosion or rot.
- Make repairs promptly:If any damage is found during an inspection, it is important to make repairs promptly to prevent further damage.
