Innovative GFRP Joints for Pultruded Frames

玻璃纤维增强塑料（GFRP）材料在结构应用中的应用尚处于起步阶段，这些材料由于其优异的耐用性和灵活的可制造性，比传统材料具有显著的优势。然而，由于连接的工程性能不佳，在许多应用中，它们与传统材料相比仍然没有竞争力。开发适合这种材料特殊特性的连接对于GRFP作为结构材料的经济使用至关重要。这项研究就是针对这样的发展，因此，可能对这种材料在结构应用中的发展产生重大影响。本工程的目的是：(1)设计用于由拉伸玻璃钢构件制成的抗弯矩框架的节点。(2)为这些接头开发高效的制造工艺。(8)在框架静力荷载和循环、准静力荷载作用下对节点进行单独试验；(4)建立可用于框架结构设计的节点简化分析模型。

Innovative GRFP Joints for Pultruded FramesParsons/Hielmstad/WhiteUniversity of Illinois at Urbana ChampaignThe use of glass fiber reinforced plastic (GFRP) materials in structural applications is in its infancy These materials offer substantial benefits over traditional materials be-cause of their excellent durability characteristics and flexible manufacturability, How. ever, they remain uncompetitive with traditional materials for many application be-cause of the poor engineering performance of connections. The development of connections suited to the particular characteristics of this material is essential to the economic use of GRFP as a structural material. This research is aimed at such a devel-opment, and, consequently, could have a great impact on the evolution of this material in structural applications.The objectives of this project are: ( 1) Design joints for use in moment resisting frames made from pultruded GFRP members. (2) Develop efficient manufacturing processes for these joints. (8) Test the joints under static loads in a frame and individually under cyclic, quasi-static loadings, (4) Produce simplified analytical models of the joints that can be used to design framed structures.
