3. Expansion joints: Mid-structure separation designed to relieve stress  on building materials. Expansion joint systems are used to bridge the gap and restore the building’s assembly functions while accommodating expected movements.

4. Shear stress: If an applied load consists of two equal and opposite parallel forces which do not share the same line of action, then there will be a tendency for one part of the body to slide over, or shear from the other part.

6.  Grandfathered:  Something that was once permitted building codes can continue to be, although the code or law has changed.

7.  Building envelope :  The maximum three-dimensional space on a zoning lot within which a structure can be built, as permitted by applicable height, setback and yard controls.


8. Easement:   A curve formed at the juncture of two members; forms a smooth transition between surfaces that would otherwise intersect at an angle.

9. Caulked Joints: Joint used for cast iron.
