“Composite Construction”. What’s to come!



Flash Program on Steel & Concrete “Composite Structures”

Structural Members that are comprised of at least two unique materials are known as composite Structures. The fundamental advantage of composite components is that the properties of every material can be joined to shape a solitary unit that performs preferable generally speaking over its different constituent parts. The most widely recognized type of composite component in construction is a steel-concrete composite.

As a material, concrete functions admirably in compression, however it has less resistance in tension. Steel, be that as it may, is solid in tension, in any event, when utilized distinctly in generally modest quantities. Steel-concrete composite components utilize concrete’s compressive quality close by steel’s resistance to tension, and when integrated, this outcomes in an exceptionally proficient and lightweight unit that is normally utilized for structures, for example, multi-story structures and extensions.
