| Abstract: | Based on the test results of 12 partially prestressed concrete beams, the crack closing charactistics is studied. A criterion of crack closing is given, and the main factors which affect crack closing are analyzed, a calculation model is founded and the program of the whole process of nonlinear analysis is drawn up, and the crack closing moment is calculated. The calculation results are quite close to the tests values. |

| Keywords: | partially prestressed concrete crack closing effect of cracked surface moment of crack closing |
