A fresh set every day. Short, practical, and written the way it actually matters on site.
Redundancy
Having more load paths than the minimum needed for stability.
On siteA redundant frame can lose a member and redistribute. A determinate one cannot — it collapses.
Creep
Slow, continued deformation under a sustained load.
On siteLong-span beams keep deflecting for years after casting, which is why long-term deflection is checked separately.
Slenderness Ratio
Effective length divided by the least radius of gyration of a column.
On siteAbove a limit the column buckles before it crushes, so a slender column fails at far less than its material strength.
Sunken Slab
A slab cast lower than the surrounding floor, usually in wet areas.
On siteIt hides the drainage run below finished floor level. Waterproofing the sunken portion is what actually matters.
Traverse
A connected series of measured lines forming a survey framework.
On siteClosing error reveals accumulated error. A traverse that does not close should never be used to set out.
