Prestressing loss of CFRP, stress/strain distribution in flange, deformation and crack distribution were studied. The results indicated that: effective width coefficient of compression top flange increased by less than 8% due to concrete cracking, long-term loading, and ordinary tension reinforcement yielding; the test value of deflection at mid-span at 1001 day was 2.322.42 times of the initial deflection, plastic deformation at 20 days after unloading was 41% of 1001 day`s; the strain of tensile reinforcement had a 65% increase than that of its initial value, and residual strain after unloading was about zero; the strain of compressed reinforcing steel bar had a 225%268% increase than that of its initial value, and residual strain at 20 days after unloading was 53% of 1001 day`s; compression strain on top plate of the box girder under long-term load increased quickly in the early stage and became stable after 2 years, and it had a 164%224% increase than that of its initial value at 1001 day; the crack width increased as time increased under long-term load, then it became stable after more or less 2 years, and it was 1.592.69 times than that of its initial value at 1001 day; most of the cracks in the bottom plate of box girder developed from middle of bottom plate, and they were wider in the middle of the bottom plate than at the bottom ends of the webs; the strain distributed over the section depth of web agreed well with plane assumption. Based on the behaviors of concrete beams prestressed with external CFRP tendons, the comformable formulars for predicting crack width of concrete box/T girder prestressed with external CFRP tendons were proposed by modifying traditional formulas in design codes for predicting the crack with of ordinary prestressed concrete beams.(5) Based on Mindlin-Reissener theories of thick plate, the fundamental geometric nonlinearity equations for flat-shell element were set up with U. L formulas. A flat-shell element was composed with the lock-free element for thick/thin plates and the four-nodded arbitrary quadrilateral finite element with in-plane rotational degree of freedom.
