Taking Roof Framing to New Heights with And-Rod Construction!

Whether you are building a new house or remodeling, roofing framing is an important part of your project. There are many different aspects of roof framing that you should know. These include compression vs tension, Collar ties, Sub-girders, and the allowable span.

Compression vs tension

Whether you are building a gable roof or a simple rafter tie, compression and tension are the basic building blocks of a roof frame. The difference between these two forces is dependent on the type of load that is applied at the joint.

Compression is a force that squashes materials while tension is a pulling force. These forces can be measured in pounds per square inch (psi). When you apply a load to a horizontal member, the top half will lengthen while the bottom half will compress.

One of the most common types of compression is when a rafter is pressed against a ridge board. Another is when a roof truss is loaded. The top chord of the roof triangle is in compression, and the bottom chord is in tension. The most popular materials are strong in compression, and can handle tension well. Other materials, such as stone, are weak in compression.

When the roof is loaded, the tension tie holds the walls back. It may look like a sagging ceiling. In addition to the weight of the ceiling, the bottom chord of the roof triangle presses against the opposing rafter in each rafter pair.

Sub-girders

Various types of sub-girders are used in the framing of roofs. They are designed to transfer loads from one roof truss to another. They can be used in buildings with difficult access or in countries with limited skilled labour. These girders are generally two-dimensional. They are usually constructed from wood members, such as solid-sawn lumber or structural composite lumber. They may be connected to each other with bolts, plywood gusset plates, or timber connectors.

For a two-dimensional truss, the structural frame is usually a lattice girder. In a lattice girder with an odd number of panels, diagonals are not affected by symmetrical loading. However, if the load is applied on all diagonals, the resulting deflection will be larger than for a lattice girder which has an even number of panels.

A truss is a type of framework in which the individual members are assembled to form a series of interconnected triangles. Most trusses are two-dimensional, although they can be modeled in a three-dimensional format.

Collar ties

During the process of framing a roof, collar ties are usually installed on the rafters. This will complete the triangulation of the roof rafters. It will help prevent rafter separation from the ridge beam. Moreover, collar ties may also provide support to the ridge assembly in high wind situations.

Collar ties are commonly made of wood, although metal straps can be used as an alternative. A metal collar tie must be at least 1–1/4 inches wide and be at least 20 gauge.

The length of the collar ties should be based on the size of the rafters, the slope of the roof, and the weight of the roof. Typically, builders use nominal lumber, such as 2x4. It is possible to use square ties, but they will not be able to be nailed to the rafter boards.

If you are making collar ties for the first time, it can be a bit of a challenge. It can be easier to hire a professional to do the job.

Allowable span

Various factors affect the allowable span of roof framing. These include rafter spacing, wood species, and load conditions. It is advisable to consult a structural engineer before building. In addition, building codes have two types of span tables.

The first table is used when the roof is not attached to a ceiling. It assumes a moderate snow load of 50 psf. This table can accommodate a house with a width of 32 feet. The second table is used when the snow load is higher. It is based on Table R802.4.1(1) of IRC-2021. It provides reduction factors for bending forces. This table is only applicable to buildings with a slope of at least 1:3 (four:12 pitch).

Alternatively, a single trimmer joist may be used to carry a header joist. In this case, the span is limited to 4 feet (1219 mm). It is also important to make sure that the ends of the joist are solidly blocked.
