Theoretical Analysis of Bending Capacity of U-Section Steel-Encased Concrete Composite Beams with the Full Connection Design
The theoretical formula is proposed for cross section’s bending capacity of simply-supported U-section steel-encased concrete composite beams. The result shows that the theoretical formula is in good agreement with the experimental results. This paper concludes that the calculated values based on current steel structure design code of China are very close to the experimental ones. Therefore, this kind of composite beams can be analyzed based on the calculation methods of composite steel and concrete beams in steel structure design code, and it is accurate to calculate the bending capacity based on the assumption of complete shear connection.
