《ACI SPEC-440.5-22：结构混凝土用玻璃纤维增强聚合物（GFRP）钢筋施工技术规范》PDF下载
规范针对以GFRP筋作为**主筋或构造筋**的现浇混凝土构件，给出**运输、切割、弯折、绑扎、定位、支撑、混凝土浇筑及成品保护**全过程要求：禁止现场明火切割与热弯，绑扎采用**尼龙或不锈钢丝**，搭接长度按**ACI 440.11-22**取值；浇筑时自由下落高度≤1.5 m，振捣点距筋表面≥50 mm，防止纤维损伤；现场须留存**批次拉伸试件与粘结拉拔试件**，确保**粘结强度≥2.5 MPa**；适用于**腐蚀环境、无磁要求及100年设计寿命**的桥梁、建筑、海工和污水处理结构，是实现GFRP钢筋混凝土从设计到落地的重要施工依据。
