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.

拉挤纤维增强塑料(FRP)结构型材开始在土木工程实践中使用。本文对拉挤玻璃钢结构的设计和性能进行了研究。重点研究了各向异性拉挤材料的横向特性对结构响应的影响。试验和理论技术将被用来获得典型拉挤FRP连接的非线性弯矩-转角数据和破坏信息，以及横向荷载拉挤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改善拉挤结构性能的一种手段。这些建议将通过ASTM委员会传递给土木工程社区和拉挤行业。
