Explore the key influences in designing and constructing buildings, including structural design and materials like steel, concrete, timber, and stone. Learn about tensile, compressive, and shear stresses, as well as overturning moments and stability. Discover the importance of materials' strength in withstanding dead loads, live loads, and various forces. Analyze the impact of wind loading, buttressing, oblique forces, and unstable structures. Delve into the history and variations of gothic structures, and examine examples like Taipei 101.

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
