The Influence of Transverse Material Properties on the Design and Performance of Pultruded Fiber Reinforced PlasticStructures

拉挤纤维增强塑料（FRP）结构形状开始在土木工程实践中使用。本研究主要考虑了挤塑玻璃钢结构的设计与性能。特别注意了各向异性拉挤材料的横向特性对结构响应的影响。实验和理论技术将用于获得非线性力矩旋转数据和失效信息的典型拉伸FRP连接；以及横向加载拉伸FRP梁的屈曲、后屈曲和破坏数据。FRP加强筋的使用将被认为是一种改善拉挤结构性能的手段。这些建议将通过ASTM委员会传递给土木工程界和拉挤工业。

Pultruded fiber reinforced plastic (FRP) structural shapes are beginning to see use in Civil Engineering practice. The design and performance of pultruded FRP structures is considered in this research. Particular attention is paid to the influence of the transverse properties of the anisotropic pultruded material on the structural response. Experimental and theoretical techniques will be used to obtain nonlinear moment-rotation data and failure information for typical pultruded FRP connections; and buckling, postbuckling and failure data for transversely loaded pultruded FRP beams. The use of FRP stiffeners will be considered as a means of improving performance of pultruded structures. The recommendations will be transmitted to the Civil Engineering community and the pultrusion industry through an ASTM committee.
