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) 结构形状开始应用于土木工程实践。 本研究考虑了拉挤玻璃钢结构的设计和性能。 特别关注各向异性拉挤材料的横向性能对结构响应的影响。 将使用实验和理论技术来获取典型拉挤 FRP 连接的非线性力矩旋转数据和故障信息；以及横向加载拉挤 FRP 梁的屈曲、后屈曲和失效数据。 FRP 加强筋的使用将被视为提高拉挤结构性能的一种手段。 这些建议将通过 ASTM 委员会传达给土木工程界和拉挤行业。

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.
