Types of Structures: Frame, Shell, Composite - JSS2 Basic technology Lesson Note

Frame Structures: These structures are composed of a network of beams and columns joined together to support loads. Examples include steel frameworks in skyscrapers and the wooden frames of houses. They are advantageous for their flexibility in design and ability to handle significant loads.

Shell Structures: These are thin, curved surfaces that distribute loads across their entire surface. Examples include domes, vaults, and certain types of roofs. Shell structures are efficient in material usage and can cover large areas without internal supports, making them ideal for auditoriums, sports arenas, and storage tanks.

Composite Structures: These structures combine two or more different materials to take advantage of their individual properties. Examples include reinforced concrete (steel and concrete) and fibreglass (glass fibres and resin). Composite structures are used in various applications, from bridges and buildings to boats and aeroplanes, due to their enhanced strength, durability, and versatility.
