The formulas for calculating flexural and shear strength, short-term stiffness and crack width of steel reinforced concrete( SRC) beams are introduced in detail, and the detailed structural requirements of SRC beams are also presented. Based on the engineering design practice, the behavior of SRC beams is studied and several problems on short-term stiffness and crack width of SRC beams are discussed.
