This paper presents the experimental results of the crack widths of 20 unbonded partially prestressed concrete composite beams with rectangular cross section. According to the research results of unbonded partially prestressed concrete beams and reinforced concrete composite beams, two kinds of formula for crack width of unbonded partially prestressed concrete composite beams are proposed. The formulas are verified by experimental data.
