纤维塑料筋混凝土梁承载力计算方法的研究

Research on Bearing Capacity Computation Method of Concrete Beam Reinforced with Fiber Reinfored Plastics Bars

建立了纤维塑料筋(FRP筋)混凝土及预应力混凝土梁承载力的计算办法,该方法将抗弯及抗剪承载力计算进行了综合考虑,与实际受力情况更为吻合,便于进行计算机模拟,并且针对FRP筋的特点考虑了目前一些规范通常所忽视的参数。最后将电算结果与试验结果进行了对比,结果吻合良好。

The bearing capacity computation method about fiber reinforced concrete and prestressed concrete beams was advised in the paper. The resistance of bending moment and shearing force was comprehensive considered in this theory, so the resuit was in conformity with stress and the theory was convenient for computer simulation. In the theory rome parameters of FRP commonly ignored by criterions were entered in consideration. Finally the result of computing was made the contrast with the test result and the result of computing was in conformity with the test result.
