What are the structural members in an aircraft or automobile structure?

 

Before we begin, let’s understand structure first. What is a structure? Structure is a Latin word which means “join together”. Anything composed of interlinked members form a structure and anything connected to that structure becomes a part of that structure. So, here I am going to share different types of structural members which eventually form an aircraft or automobile structure.

The name of every member is driven by the type and direction of loading. Following are the types of structural members in structural engineering:

Strut/Column/Post: Member which is subjected to compressive load along the longitudinal axis. The slenderness ratio of a member decides whether it is a column or a strut.

Tie: Member which is subjected to tensile load along the longitudinal axis is known as tie. Imagine you are pulling something, that’s tie.

Beam: When the load on a member is in transverse direction, that member is known as beam. Beam is the most common structural member and has the maximum share in a structure. Beam analysis is generally carried out to depict the failure of such structural member.

Beam-tie: Any member which is under a tensile as well as transverse loading is known as beam-tie. The advantage in this kind of member is that the bending action due to transverse loading is resisted by the tensile loading in the longitudinal direction.

Beam-column: Any member which is under a compressive as well as transverse loading is known as beam-column. The disadvantage in this kind of member is that the bending action due to transverse loading is further assisted by the compressive loading in the longitudinal direction.

Plate: Any member which is placed vertically and is under a pressure loading is known as plate. The calculations associated with plates are driven from graphical plots.

Panel: Any member which is placed horizontally and is under a pressure loading is known as panel. The calculations associated with panels are driven from graphical plots.

Shell: Any curved member having radius of curvature and is under a pressure loading is known as shell. The stresses produced in shells are known as hoop stresses.
