Structural layout and design analysis is the phase where a building’s geometry, framing, and load paths come together before anything is built. Engineers build a model of the whole structure, apply the loads it must carry, and size every member so the finished building stands safely for decades. Decisions made in this phase determine whether […]
In structural engineering, the word member describes any individual load-carrying element in a building frame: columns, beams, girders, truss chords, bracing, and ties. Each member is sized and detailed to resist specific forces, and the performance of the whole frame depends on how those parts work together. The core skills in steel structure design, covering
In residential and light commercial construction, a tall wall is any wall taller than 10 feet: great rooms with cathedral ceilings, stairwells, two-story entries, and commercial storefronts. Height changes the engineering. Wind pressure grows with exposure height, studs get more slender, and deflection becomes visible to the eye. Tall walls are where structural analysis meets
Roof trusses carry the weight of the roof and transfer it to the walls, and most residential and light commercial roofs in North America use them. Truss plants fabricate these engineered frames in a controlled shop, then deliver them to the site ready to set. The industry behind them keeps consolidating, and the strategic expansion
Engineered wood products, usually called EWP, have replaced much of the dimensional lumber in modern floor and roof framing. I-joists, laminated veneer lumber, and glulam beams carry more load over longer spans with less waste than solid lumber, and every one of them comes with published design values. The selection process follows the same logic
Every framed building depends on small steel parts that most homeowners never see. Structural connectors, anchors, and fasteners tie rafters to walls, walls to foundations, and decks to houses, and each one carries a load rating that is tested and printed by the manufacturer. The plants that make these parts are among the most capital-intensive
Timber frame construction has been used for centuries and is enjoying a sustained revival, because it delivers something stick framing rarely can: exposed structural timbers, dramatic interior volume, and a visible record of craftsmanship. The frame does real structural work, carrying roof loads down through principal posts to the foundation. That load path begins at
The fire that swept through Notre Dame Cathedral in Paris on April 15, 2019 destroyed timber that was more than 800 years old. The frame, known as The Forest, earned its name honestly: it required a literal forest’s worth of oak, with beams felled sometime between 1160 and 1170, each one cut from a different
A truss does two jobs in a timber frame home. Structurally, it carries roof and wall loads down to the posts; visually, it defines the character of every room it crosses. Both jobs depend on the same geometry, which is why the basics of efficient long-span structural framing matter before style preferences enter the conversation.
Most people picture a campfire when they think of wood and flame: dry sticks burning hot and fast. Heavy timber behaves differently. Large posts and beams char slowly and predictably under fire, and that char layer protects the structural core long enough for people to evacuate and firefighters to work. The behavior is so well
