Abstract
A study on fatigue behavior of unbonded partially prestressed concrete beams is presented. Model tests have been carried out in static loadi ng and cyclic compressive loading on 15 beams with flexure. The ratios of the lower limit to the upper limit of fatigue load are 0.5 and 0.3 respectively, and the frequencies of cyclic loading are 8 Hz and 4.5 Hz respectively. The experimental results of the strains of the concre te and steel bars, the deflection of test beams, and the crack width o f normal section are analyzed. According to statistics and analysis of test results, the corresponding calculation models are developed and presented.
