摘要/Abstract

摘要： 分析了复合材料轻质桥梁中的快速连接接头的受力,提出了一种大拉力接头的构造,完成了一批接头的拉伸试验和桥跨模型试验,证实了接头具有足够的承载能力,并依据破坏模式建议了接头的改进构造。还采用有限元软件对桥跨模型试验中的接头进行了分析,其破坏模式和破坏承载力与试验吻合。

关键词: 复合材料接头, 铺层方案, 破坏模式

Abstract: The mechanical properties of FRP (Fiber-Reinforced Polymer) joints for rapid installation in lightweight bridges have been analyzed. A configuration for tension force joints is presented, and tension test and bridge span test for the joints are completed. It shows that the bearing capacity of FRP joints is sufficient. The improvement of joint is given based on the failure mode in test. Finite element analysis for tested joints is conducted, in which the failure modes and bearing capacity have good agreements with experimental results.

Key words: fiber-reinforced polymer joints, stacking sequence, failure mode
