Abstract: According to the provisions of clause 5.2.4 in Code for design of concrete structures (GB 50010—2010), the impact of the floor slab as a flange to the rigidity and bearing capacity of the beam should be considered. According to the different floor slab assumptions, the methods to correct the rigidity of T-shaped beams, and how to choose the values of the bending-moments and axial-forces of the T-shaped beams were discussed.

Keywords: T-shaped beam; rigid floor slab; elastic plate 6; elastic plate 3; elastic membrane; amplification coefficient of rigidity; tensile compression effect of pure bending
