摘  要:
以CFRP筋作无粘结预应力筋同时配置一定数量的非预应力钢筋,设计制作了4根无粘结预应力CFRP筋混凝土简支梁,通过静载试验考察该类构件的受弯性能。在对试验数据进行分析的基础上,提出了适合无粘结预应力CFRP筋混凝梁的应力增量计算公式。

摘  要:
4 unbonded partially prestressed CFRP(Carbon Fiber Reinforced Plastics) reinforced concrete simple beams are de-signed,which are reinforced with CFRP unbonded tendons and a certain number of non-prestressed steel bars.The flexural perfor-mance of this kind of beam is investigated.On the basis of analysis on test data,the calculating Formula of stress increment for con-crete beams prestressed with unbonded CFRP tendons is Proposed.
