内容简介

本书介绍了汽车与桥梁耦合振动的研究现状及发展展望, 汽车与桥梁耦合振动分析理论和方法及相关计算模型的建立, 桥针对中小型桥梁中伸缩缝的频繁损坏问题, 采用生态高延性水泥基复合材料 (Eco-HDCC) 浇筑桥面无缝连接板, 替换伸缩缝。Eco-HDCC具有优越的极限延伸率和较小的裂缝宽度, 在工程应用上有很大的前景。玄武岩纤维增强聚合物 (BFRP) 筋作为增强筋材, 在众多筋材种类中, BFRP筋的受拉弹性模量与Eco-HDCC的受拉弹性模量*为接近, BFRP筋与Eco-HDCC协同变形, 可提高结构的承载力, 在桥面无缝连接板中配置BFRP筋。本文以获得Eco-HDCC桥面无缝连接板设计方法为目标, 从Eco-HDCC材料性能、BFRP筋增强Eco-HDCC构件性能以及桥面无缝连接板结构性能三个层次进行研究。
