UNIT 2 part B STRUCTURAL REQUIREMENTS FOR BUILDINGS (continued)
Key influences in designing and constructing buildings • structural design • structural materials
STRUCTURAL DESIGN • Strength the materials used in the construction of the building must have adequate to support all applied loads • dead loads • live loads • Stability must be capable of withstanding all appled forces without becoming unstable
Tensile stress Compressive stress
STRUCTURAL MATERIALS • Timber, stone, brick - oldest most traditional materials. Generally limited to smaller structures. • STEEL • Widely used from thinnest sheets to solid sections. • Good in tension, not quite so good in compression. • Used in solid sections, reinforcing bars, tubular sections and cables • CONCRETE • Predates steel/iron as a construction material. Good in compression, weak in tension – hence reinforced concrete
