A purlin is a secondary structural member that spans between the primary/main steel frame to support the roof cladding. … Light gauge cold-formed steel roof purlins are used on a wide range of building types including retail and leisure, industrial, warehouses and distribution, healthcare and education.

Crane girder: The principal horizontal beams of the crane bridge which supports the trolley and is supported by the end trucks. Crane Span: the horizontal distance center to center of the runway beams.
Composite columns are a combination of two traditional structural forms: structural steel and structural concrete. As composite columns were generally developed after steel columns and reinforced concrete columns, their design approach could have been based on either steel or concrete design methods.
Composite beams are constructed from more than one material to increase stiffness or strength (or to reduce cost). Common composite-type beams include I-beams where the web is plywood and the flanges are solid wood members (sometimes referred to as “engineered I-beams”).
Tension members are structural elements that are subjected to axial tensile forces. Examples of tension members are bracing for buildings and bridges,
A member which carries an axial compression is known as a compression member. It is also called a strut. … Such a compression member is known as a short column. For large values of KL/r, a compression member undergoes buckling i.e., side way deflection (Figure 4.1(b)).

Loads on the chassis frame are weight of the vehicle and the passengers, which causes vertical bending of the side members. Vertical loads when the vehicle comes across a bump or hollow, which results in longitudinal torsion due to one wheel lifted with other wheels at the usual road level. Loads are dynamic in nature.
A shear connection is a joint that allows the transfer of shear forces between two members. It is a connection with pure normal force load (tension joint), pure shear loading, or combination of normal and shear force. Shear connections are generally the most commonly used connections
Pretensioned A pretensioned joint is a joint that transmits shear and/ or tensile loads in which the bolts have been installed to provide a pretension in the installed bolt. Bolts can be pretensioned using turn-of-nut, calibrated wrench, twist- off-type tension-control bolt or direct-tension-indicating washer methods.

The continuous supported beam can withstand greater loads by providing greater bending resistance along the length of the beam. A continuous beam is a beam that is loaded and has more than two supports.

Mechanically laminated built-up columns are formed by fastening two or more members with bolts, nails or screws. If built-up members have spacer blocks between the members, they create a spaced column. The design of built-up columns is different from the design of solid columns.
Single-angle section beams are generally loaded parallel to their geometrical axes and their cross-sections are not symmetrical to their principal axes. Even equal leg angle beams have only one symmetrical axis. Many types of loading cause biaxial bending and axial forces in these members.
