This type of weld is the most common in structural steel fabrication:

In this type of concrete, the steel is pretensioned before the superimposed load is applied:

This is a common method for connecting steel members of buildings and bridges:

This type of structural steel drawing shows all dimensions necessary for fabrication:

A piece mark should be shown wherever a separately handled member appears on the drawings.

Due to wood loss in surfacing, the nominal size of structural timber is larger than its dressed thickness.

Many different types of wood are used as structural timber.

These are joined together in the field to build a structure:

Reinforced concrete has embedded steel reinforcing bars.

Brick and tile are some of the less common forms of building construction.

AISC recommends one standard connection for attaching beams.

These plans, made by the steel fabricator, are assembly drawings for the steel structure:

This material is used in masonry construction, most commonly for ornamental facing:

The surface of a wood product is finished by milling or planing.

Symbols are seldom used to indicate requirements for finished surfaces on wood.

Riveting is seldom used as a connection method in structural steel.

Shop drawings consist of detail drawings of all parts of the entire structure showing exactly how the parts are to be made.

Tolerance stacking has little effect on the fit of steel members.

Most CAD programs have structural shapes symbol libraries available.

Structural steel is available in two standard shapes.
