Distinguish between rcc and composite structure
Answers
Concrete has a high compressive strength and very low tensile strength(not taken into consideration)
For a rc structure to be stable it has to bear both the tensile and compressive stress so in order to take both the tensile and compressive stresses
concrete structure is provided with extra tensile strength by using steel bars, hence due to addition of steel reinforcement its called as Reinforced concrete structure
●rcc can be used framed structures and load bearing structures
● percentage of steel used should not exceed the specified in code generally its 4%
Composite structures
When 2 materials are used during the construction thn the structure is known as composite structure
●composite section are used when we require two different properties
●composite section of concrete and steel has solid steel sections like I section and steel tube
● composite concrete and steel sections are used in high rise buildings and in tube structural systems etc
● high rise buildings like burj khalifa have been built using composite structure
