Theoretical analysis of steel-encased concrete composite beams;

Aiming at some problems of common steel-concrete beams, this article puts forward a new type of composite beam-steel-encased composite beam.

Based on the analysis of some problems about the common steel-concrete composite beam, this article puts forward a new type of steel-encased composite beam.

It is a new form of reinforcement for concrete structure to strengthen them with combination of bonded steel angles (BSA) and carbon fiber reinforced polymer sheet(CFRP).

It is a new form of reinforcement for concrete structure to strengthen them with combination of bonded steel angles (BSA) and carbon fiber reinforced polymer sheet(CFRP) ,which must be proved safe and functional in rehabilitation and strengthening of concrete structure .
