Behaviour And Properties Of Concrete And Steel

steel structures vs concrete structures | complete,concrete structure: steel structure: durability: the concrete structure are more durable : the durability of steel structure is adversely affected by weather condition and rusting: earthquake resistance: the concrete structure are brittle so they are less earthquake resistance. steel structure can withstand earthquake more effectively than concrete structure.[pdf] mechanical properties and behaviour of concrete,concrete exhibits excellent resistance to compressive forces, but is brittle and weak in tension. various types of fibres have been investigated by many researchers to improve the ductility and energy absorption capability of concrete materials and structures under static and blast and impact loadings. spiral-shaped steel fibres were recently.
