Innovative GFRP Joints for Pultruded Frames

用于拉挤框架的创新GRFP接头Parsons/Hielmstad/White伊利诺伊大学厄巴纳香槟分校玻璃纤维增强塑料(GFRP)材料在结构应用中的应用尚处于起步阶段，这些材料提供了比传统材料更大的好处，因为它们具有优异的耐久性和灵活的可制造性。然而，由于节点的工程性能较差，在许多应用领域，它们仍然无法与传统材料相媲美。开发适合这种材料的特殊特性的连接件对于将GRFP作为结构材料的经济使用是至关重要的。这项研究就是针对这一发展而进行的，因此，可能会对这种材料在结构应用中的发展产生重大影响。本项目的目标是：(1)设计用于由拉挤玻璃钢构件制成的抗弯框架的节点。(2)为这些接头开发高效的制造工艺。(8)对框架内节点进行静力试验，并分别在循环、准静态荷载作用下进行试验；(4)建立简化的节点分析模型，用于框架结构的设计。

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.
