Abstract

Pultruded Glass Fiber Reinforced Polymers (PGFRPs) are becoming a new mainstream in civil construction because of their advantageous properties. One of two main elements, glass fibers, have been constructed by unidirectional glass roving in applicate progress. PGFRPs do not have high shear strength, which is determined by another element is the matrix. In the future, the demand for enhanced serviceability of existing PGFRP structures could be seen as unavoidable. Therefore, multi-bolted connection being the most typical type of connecting member, strengthening the connection performance of PGFRPs through connection is necessary. Previous researchers have studied several methods for improving connection capacity, including pasting glass fiber sheets (GFS). However, experimental research is lacking for multi-bolted connection. This study investigated several strategies of specimens, including the quantity of bolts (two bolts, four bolts, and five bolts); the end distance/diameter ratio ( = ; = ) under tensile load; and three types of glass fiber sheets (GFS) (0°/90°, ±45° and chopped strand mat (CSM)). The experiment's results showed the strengthening effects and the failure mode on the specimens. These findings could address the gap in knowledge that needs to be resolved with respect to PGFRPs' composite design, through evaluation and discussion of their behavior.

摘要

拉挤玻璃纤维增强聚合物（PGFRP）因其优越的性能正在成为民用建筑领域的一种新主流材料。其两个主要成分之一的玻璃纤维，在应用过程中是由单向玻璃粗纱构成的。PGFRP的抗剪强度不高，这取决于另一个成分即基体。未来，提高现有PGFRP结构的使用性能的需求将不可避免。因此，多螺栓连接作为最典型的连接构件类型，通过连接来增强PGFRP的连接性能是必要的。此前的研究人员已经研究了几种提高连接能力的方法，包括粘贴玻璃纤维片材（GFS）。然而，对于多螺栓连接缺乏实验研究。本研究调查了几种试件策略，包括螺栓数量（两个螺栓、四个螺栓和五个螺栓）；拉伸载荷下的端距/直径比（ = ； = ）；以及三种类型的玻璃纤维片材（GFS）（0°/90°、±45°和短切毡（CSM））。实验结果表明了试件的增强效果和破坏模式。通过对其性能的评估和讨论，这些发现可以填补PGFRP复合材料设计方面需要解决的知识空白。
