Structural Steel Construction

The method of building using prefabricated steel components assembled on-site.

Prefabrication

The process of manufacturing building components in a factory before transporting them to the construction site.

Load-bearing Masonry

A type of construction where walls carry the weight of the building.

Cast-in-place Concrete

Concrete that is poured into forms and allowed to cure on-site.

Framing Plan

A detailed outline of structural framing in a building, typically presented in plan view.

Structural Grid

A network of intersecting lines that helps determine the placement of columns in a building.

W-sections

Wide-flange steel sections commonly used for horizontal and vertical structural elements.

Bolts

Fasteners used to hold structural components together, categorized into common bolts and high-strength bolts.

Welding

A process of joining metal parts through heat, allowing them to fuse together, often with the addition of molten metal.

Rigid Connection

A type of connection that maintains fixed angles and transfers both shear and moment between framing members.

Column Splice

A connection that joins two column segments, typically required in tall structures due to the limited length of steel members.

Steel Detailing

The process of creating detailed drawings that specify the connections and dimensions of steel components.

Erection

The process of assembling a building's structure at the construction site.

Connection Types

Various methods used to join structural components, including column-to-beam and beam-to-beam connections.

Braced Frame

A structural system that uses diagonal elements (bracing) to provide stability against lateral forces.
