Concrete structures perform well in fire. This is because of the coination of the inherent properties of the concrete itself, along with the appropriate design of the structural elements to give the required fire performance and the design of the overall structure to ensure robustness.
The prestressed concrete design of a structure is influenced by either of the two processes, pre-tensioning, and post-tensioning. Pre-tensioning can be further classified into two egories such as linear pre-tensioning and circular pre-tensioning.

Concrete-steel composite structures - Designing Buildings Wiki - Share your construction industry knowledge. Structural meers that are made up of two or more different materials are known as composite elements. The main benefit of composite elements is that the properties of each material can be coined to form a single unit that performs better overall than its separate constituent parts
