in reinforced concrete, particularly under extreme conditions like fire or high stress. Paper Draft

While "TOH" is not a standard industry-wide acronym for a specific crack type, it is often used informally in local or project-specific contexts to refer to cracks occurring at the (roof slabs or upper-level columns) or Top of Head (top of a concrete "bent" or pier cap).

Precise modeling reveals how rebar placement affects crack patterns: Tensile Membrane Action (TMA):

tool allows for the rapid generation of complex reinforcement schedules, including: Stirrups and Links: Accurate placement for shear resistance. Slab Mesh: Modeling light anti-crack reinforcement in composite decks. Footing and Column Detailing:

Toh Rebars is a powerful SketchUp extension developed to automate the complex process of drawing reinforcement bars in 3D models.
