Retaining walls are essential structural elements that provide lateral support to soil, preventing movement and maintaining stability on sloped or excavated sites. The design of a retaining wall involves not only ensuring adequate strength of the concrete stem, footing, and shear key (if used), but also verifying global stability against sliding, overturning, and bearing failure.

Bolted connections are a fundamental part of structural steel design. While many connections are loaded primarily in shear or tension, combined loading is common in real-world structures — and must be addressed explicitly in design.

Wood screws are widely used in timber construction for their convenience and versatility. When a wood screw is subject to both lateral (shear) and withdrawal (tension) forces, proper design is essential to avoid brittle failures.

Lag screws are widely used in timber construction to transfer loads between wood members and steel plates or anchorage points.

Bolted timber connections are essential in wood-framed structures, especially when transferring high loads between beams, columns, or other framing elements.

Glulam (glued-laminated timber) is a versatile and high-performing material used in wood-framed structures where longer spans or higher loads are required.

Designing timber columns according to the National Design Specification (NDS 2018) is a fundamental task for structural engineers working with wood-framed buildings.

Designing timber beams according to the National Design Specification (NDS 2018) is a fundamental task for structural engineers working with wood-framed buildings.

Welded connections are a common part of steel design—but when you're dealing with unsymmetrical shapes like channels (C-shapes), the analysis can get tricky fast.

Braced frames are a key structural system, providing a stiff, efficient, and cost-effective solution for resisting lateral loads.

In this blog post, we focus on shear flow design for the weld between the flange and the web (or stem) of a steel tee per AISC 360.

Fillet welds between elements in welded profiles play a crucial role in transferring shear forces and maintaining structural integrity.

Follow along for a step-by-step moment connection design example using CalcBook.

Moment frames are a vital part of structural engineering, offering a robust and flexible solution for lateral load resistance.

When designing steel moment connections, ensuring the column web can transfer the applied forces is critical.

Check connections for flange local bending, web local yielding, web local crippling, web sidesway buckling, and web compression buckling.

Weld design plays a critical role in ensuring the strength and stability of structural connections.

Bearing pressure demands, critical section bending, shear forces, and the evaluation of sliding, overturning, flexural and shear capacities.

When designing steel structures, accurately determining the section properties of built-up steel members is crucial.
