Structural Engineering questions, answered by experts

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

It’s possible to drill into an LVL beam, but you should always avoid it. LVL beams are major structural components of your home, and drilling into them can weaken them and lead to cracking over time. If you need to drill into an LVL beam, consult a structural engineer. They’ll know the bit size, depth, and directionality that’s safe to use when drilling.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.
