| Abstract: | This paper presents the experimental results of the deflection tests of 20 unbonded partially prestressed concrete composite beams. basedon to the metioned work and the previous studies on reinforced concrete composite beams, two deflection formulas of unbonded partially prestressed concrete composite beams are proposed. The values calculated are in good fittness with those tested. The comparison demonstrates the adoptability of the formular in ergineering design. |

| Keywords: | unbonded prestress partially prestressed concrete composite beams shortterm deflection |
