Bearing Wall

A type of wall either made of masonry or concrete that supports more than 2.90kN/m of vertical load in addition to its own weight.

Exterior Wall

These are walls that define the exterior boundaries of a building and that has a slope of 60 degrees or greater with the horizontal plane.

Purlin

A steel member that carries the roof load between trusses or rafters.

Lintel

It carries the masonry across the opening made by a door or window.

Parapet Wall

A part of the wall that is above the roof line.

Moment Arm

It is the shortest distance of a force from the point or axis.

Building, Enclosed

A building that does not comply with the requirements for open or partially enclosed buildings.

Base Shear

It is the total design lateral force or shear at the base.

Story Drift Ratio

It is the story drift divided by the story height.
