Building structure design refers to the process of creating a safe, stable, and functional framework for buildings. It involves determining the structural systems, materials, and components that can support the intended use of the building while ensuring structural integrity, safety, functionality, and cost-effectiveness. Structural engineers play a key role in this process by designing the structural elements, selecting appropriate materials, and ensuring the building can withstand anticipated loads through analysis and calculations. Important factors considered in building structure design include architectural design, site conditions, building codes, load requirements, and construction methods.
