CIV220H1 Lecture Notes - Lecture 16: Road Slipperiness, Thermal Expansion, Reinforced Concrete
Document Summary
Materials properties we are interested in highway bridge i cost thermal expansion strength durable to the environment density environmental impact asethetics stiffness skid resistance. Materials properties we are interested in columns in tall building strength thermal expansion cost. Fire resistence are intrested in cladding in tall building loads. Cost experience durable local expertise last for intended service life user friendly repaired or replaced. I life safety issues building codes is strong in compression but is is strong in tension and compression but small in compression steel also loses its. Timber has high toughness and strength to weight ratio but consumed by fire. Concrete is typically both stiff weak in tension brittle. Reinforced concrete carries compression and provides fire resistance while the embedded steel bars carry tension making member ductile if designed. Materials deform under loads is a composite material where condrete the composite constructed properly iiti.
