INTERMEDIATE MOMENT RESISTING FRAME (IMRF) : A concrete moment resisting frame designed in accordance with Sec 8.3. … SHEAR WALL : A wall designed to resist lateral forces parallel to the plane of the wall (sometimes referred to as a vertical diaphragm or a structural wall).
Special concentrically braced frames (SCBFs) are among the most common steel structures for resisting earthquake loads in high seismic regions. Concentrically braced frames (CBFs) are elastically designed as one vertical truss system to resist lateral loads through axial brace members when they are introduced.

Z purlins or zed purlins are horizontal beams that are designed to form the roof and wall joists of a building shell structure (also view our C section purlins page). They sit between the roofing sheets and the building, acting as a support for the sheet to ensure it is firmly attached and safely in place.

A stud is a vertical framing member which forms part of a wall or partition. Also known as wall studs, they are a fundamental component of frame construction and are typically made of timber. However, steel studs are increasingly popular, particularly for non load-bearing walls and firewalls.

Shear walls are generally located at the sides of buildings or arranged in the form of core that houses stairs and lifts. Due to functional requirements such as doors, windows, and other openings, a shear wall in a building contains many openings.

In structural engineering, a shear wall is a vertical element of a system that is designed to resist in-plane lateral forces, typically wind and seismic loads. In many jurisdictions, the International Building Code and International Residential Code govern the design of shear walls.

A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity; a TUBE is a round, rectangular, squared or oval hollow section measured by outside diameter (OD) and wall thickness (WT), expressed in inches or millimeters.

A gusset plate is a thin metal object, typically made of steel, that is used to affix independent members of a structure to each other or to a beam to aid alignment. Gusset plates are used in joint, bend or otherwise disjointed structural locations that require additional support to withstand stresses.

Two-by-six and two-by-four are the most common dimensions of wall studs. Standard walls of 8 feet have wall studs that are 92 inches. The studs are 104 1/2 inches in homes with 9-foot walls. Pre-cut studs are used in homes with a 10 foot wall.

DESIGN OF STEEL BEAMS. BEAMS Beams span between supports to carry loads which are resisted by bending and shear. However, deflections and local stresses are also important. Beams may be cantilevered, simply supported, fixed ended or continuous.

These include timber beams which support lightweight concrete strips used as floor slabs in many timber homes. Concrete filled resin composite boxes are often used in the construction of bridges. They are strong, quick to fabricate, and relatively light weight requiring a minimum of heavy machinery to put in place.

Eccentrically braced frames (EBFs) are a relatively new lateral force resisting system developed to resist seismic events in a predictable manner. Properly designed and detailed EBFs behave in a ductile manner through shear or flexural yielding of a link element.

The perimeter members of a diaphragm that are parallel to the applied lateral force are the collectors and their function is illustrated in Figure 9.4 (Sec. 9.2). The term collector is generally used in this book because it is the term frequently used in the IBC

Drag loads are due to lateral (horizontal) loads generated in high-wind or seismic events. These loads are generated within the structure and transferred into load carrying elements (like drag strut trusses, shear walls or roof diaphragms) which then transfer the loads to the foundation and then safely into the ground.

Bridges where the deck slabs and the main girders work together to resist loads are called composite girder bridges, and bridges designed to resist loads with the main girders only are called non-composite girder bridges.
