【摘要】 本文在一定的简化条件下建立弯曲先后几何关系,得到弯曲角度和结构延伸率之间的方程式,并以半圆型肋说明这种关系的具体应用,对可弯曲、屈服和延性之间的关系进行讨论,以玻璃纤维增强聚丙烯可弯曲型FRP筋为例,说明如何在工程上实现可弯曲型FRP筋生产、弯曲等内容,最后对玻璃纤维、聚丙烯之间的界面进行专门论述,并给出类似的实例。更多还原

【Abstract】 Based on some predigesting conditions,the equation about the configuration elongation ratio-the bending angle was got,and some computing figures based on the equation were given.A semicircle rib was as an example to illustrate the equation.The relationship of bending ability,yielding and ductility for FRP rebars was discussed.The glass fiber reinforced Polypropylene rebars was an example to explain the process of production and bending. Finally,the interface between glass fiber and Polypropylene was specially discussed,and a similar example was given.更多还原
