The objective of this project is to conduct an experimental and theoretical investigation into the behavior and design of concrete beams reinforced with three-dimensional (3-D) prefabricated fiber reinforced plastic spatial reinforcement cages. 3-D spatial reinforcement cages, most conveniently fabricated from pultruded grating components, will require innovative research in the areas of manufacturing, design, modeling, analysis and construction economics. Based on results of a recently conducted pilot study it appears that 3-D FRP reinforced beams have significant structural potential due to their ability to fail progressively in a pseudo-ductile manner. They also appear to have significant construction potential due to their prefabricated industrialized manufacturing that could yield construction cost saving because of reduced labor costs. The research will focus on the following items: Development of new integrated 3-D FRP pultruded reinforcement cages, characterization of mechanical properties of 3-D pultruded reinforcement cages, optimization of elements for 3-D reinforcement cages, design and analysis of concrete beams reinforced with 3-D FRP cages, and a study of the construction productivity and economic benefits of the use of 3-D FRP cages.

本项目的目的是对三维（3-D）预制纤维增强塑料空间钢筋笼加固混凝土梁的性能和设计进行实验和理论研究。三维空间钢筋笼，最方便地由挤压光栅组件制造，将需要在制造，设计，建模，分析和建筑经济学领域的创新研究。根据最近进行的一项初步研究的结果，三维FRP增强梁具有显著的结构潜力，因为它们能够以伪延性方式逐渐失效。由于其预制的工业化制造，由于降低了劳动力成本，可以节省建筑成本，因此它们似乎具有巨大的建筑潜力。研究将集中在以下项目：新型集成三维玻璃钢拉挤钢筋网箱的开发，三维玻璃钢拉挤钢筋网箱的力学性能表征，三维玻璃钢拉挤钢筋网箱元件的优化，三维玻璃钢拉挤钢筋网箱加固混凝土梁的设计与分析，以及使用三维玻璃钢拉挤钢筋网箱的施工生产率和经济效益的研究。
