Such parameters as the percentage of ordinary reinforcment, amounts and configuration of unbonded prestressed tendons, the ratio of span to depth and the loading patterns were considered. Based on the results, the fomula for the eqivalent length of deformation zone on the beams at ultimate were developed. A simple formula was developed for the ultimate mid-span deflection of concrete beams with concept of equivalent length of deformation zone, and the deformation of beam before internal reinforcement yielding was predicted by the traditional formula for the deformation of partically prestressed concrete beam. Then an analytical model was deduced for analyzing the ultimate stress increment in those concrete beams prestressed with external or internal unbonded tendons based on the mid-span deflection.(4) Testes were carried out on a thin-walled concrete box beam presressed with external CFRP tendons to study its short-term performances under uniform load, long-term behaviors under uniform load, and full-time performance under four-point load in turn.

In some buildings it is unable to apply strengthening measurements on the upper surface of the reinforced concrete continuous beam. On the basic character of RC continuous beam moment redistribution, a new method was tried to increase the beam's resisting moment capacity. The Carbon Fiber Reinforced Plastic was bonded on beam bottom of the span-mid, the flexural capacity of span-mid was increased, and the plastic hinge joint at the beam end was formed.
