Structural engineering is a branch of civil engineering that focuses on the design and analysis of structures, ensuring they can withstand various forces and loads. This field involves creating safe and efficient buildings, bridges, and other infrastructures by understanding materials, forces, and environmental impacts. Structural engineers use mathematical and scientific principles to calculate the strength and stability of structures. They work closely with architects and construction teams to ensure that designs are not only aesthetically pleasing but also functional and safe. Key materials in structural engineering include steel, concrete, and wood.
