EXPERIMENTAL STUDY OF FATIGUE ANTI-SHEAR BEHAVIOR OF UNBONDED P.P.C BEAM

Based on the fatigue test data of eight unbond partial prestressed concrete (P.P.C) beams, the oblique cleavage mechanism and fatigue shear strength in oblique sections of unbond P.P.C beams are analysed and studied in this paper under upper limit and lower limit of fatigue load. The calculating formula of fatigue shear strength composition coeficient in oblique sections are put forward. Relations of the load characteristic value and load amplitude coefficient that influences fatigue with the circular frequency of dynamic load are discussed. The regression formulas are established as well. Results calculated by the formula are compared with those obtained in the experimental test.
