ART-101 Lecture Notes - Lecture 10: Precast Concrete, Reinforced Concrete, Pendentive
Document Summary
Architecture- fulfill the practical and expressive needs of culture: usable, stable and permanent, communicate aesthetic experience though the use of form and idea. Two conditioning factors: economic- minimum cost, maximum stability, expressive- materialize feelings and attitudes. Produce a stable structure: compression, tension, bending. Weakness: hard and expensive to quarry and transport, heavy, weak tensile strength/support capacity. Rubble- used by roman, bonded with mortar, naturally shaped, used stucco over. Brick: first use: 4,000 bce mesopotamia, expanded use by romans, similar to stone, easier to move and shape, only as strong as mortar, greater freedom in application and shapes. Wood: good tensile and compressive strength, easy obtain and work, negatives: termites, fire, positives: cheap, light, and practical for floors and roofs, moving low bearing walls expensive. Iron and steel: not used until 1800, tremendous compressive strength, tensile strength, workability, derivation of iron, two disadvantages: metal fatigue and rust.
