What is the primary purpose of structural connections?

• A. To decorate the structure
• B. To transfer loads between elements
• C. To reduce weight
• D. To resist weather

Answer: (B)

Structural connections exist to move forces from one element to another, creating a continuous load path through the building. By tying beams to columns and joining floors to walls, they carry gravity loads down to the foundations and transfer lateral forces from wind or seismic into the frame, maintaining shape and stability even as the structure creeps, settles, or sways. They must resist shear, bending, and axial forces while allowing controlled movement and keeping members properly aligned. Decoration, reducing weight, or weather resistance are not the primary roles of these joints; those aspects may be relevant in other ways, but the essential function of a structural connection is to transfer loads safely and keep the structure stable.
