FRP（纤维增强塑料）作为一种新的建筑材料最近引起了人们的注意。本文介绍了一种新型的人行板桥的开发，它采用玻璃纤维增强塑料（GFRP）纸浆型材通过胶粘层粘结在一起，可以显着提高经济效益。创新的特点是适当采用半固定支撑条件，在两端使用锚栓，以大幅减少弯曲挠度，这往往成为主导的玻璃钢人行天桥的设计。本文通过材料试验，对两种GFRP筋板型材的材料性能进行了测试，并在此基础上对新型人行板桥进行了试设计。接下来，进行了使用真实的尺寸的部分模型的弯曲载荷试验，并且还进行了分析检查，以研究模型和试验设计桥梁的静态和动态弯曲变形特性。从这些结果中，证明了这种新设计的实际应用是高度可行的。
FRP (Fibre-Reinforced Plastic) has recently drawn attention as a new construction material. This paper deals with the development of a newly proposed pedestrian slab bridge using GFRP pultrusion profiles bonded together by adhesive layers, which can significantly improve the economic efficiency. The innovative feature was the appropriate adoption of semi-fixed support conditions using anchor bolts at both ends in order to sharply reduce the bending deflection which often becomes dominant in the design of GFRP pedestrian bridges. In this study, material tests were done in order to measure the material properties of two kinds of GFRP pultrusion profiles, and a trial design of this new pedestrian slab bridge was carried out based on those properties. Next, bending load tests using a partial model of real size were done, and analytical examinations were also carried out in order to investigate the static and dynamic bending deformation characteristics of the model and of the trial design bridge. From these results, it was proven that practical application of this new design is highly feasible.
