作为美国联邦公路管理局(FHWA)生命高速公路计划资助的创新项目的一部分，开发了一种全深度预制超高性能混凝土(UHPC)华夫板和适合现场实施的华夫板连接。在实验室条件下对由两块不同类型连接的面板组成的单元进行了成功的全尺寸验证测试后，华夫面板成功安装在爱荷华州瓦佩洛县的一座替换桥梁上。随后的荷载试验证实了超高性能混凝土华夫上承桥的良好性能。利用已完成项目的经验教训和对华夫面板进行一系列简单而详细的有限元分析的结果，本报告旨在为扩大新桥和现有桥梁中UHPC华夫面板的设计和安装提供指导。在对超高性能混凝土和华夫板进行介绍并总结已完成的工作之后，本文件介绍了华夫板设计、连接设计、使用华夫板进行重新铺装以及超高性能混凝土华夫板的预制制造、施工和安装指南。
As a part of an innovation project funded by the Federal Highway Administration (FHWA) Highways for LIFE program, a full-depth precast, ultra-high-performance concrete (UHPC) waffle deck panel and appropriate connections suitable for field implementation of waffle decks were developed. Following a successful full-scale validation test on a unit consisting of two panels with various types of connections under laboratory conditions, the waffle deck was installed successfully on a replacement bridge in Wapello County, Iowa. The subsequent load testing confirmed the desirable performance of the UHPC waffle deck bridge. Using the lessons from the completed project and outcomes from a series of simple and detailed finite element analyses of waffle decks, this report was developed to serve as a guide for broadening the design and installation of the UHPC waffle deck panel in new and existing bridges. Following an introduction to UHPC and waffle deck panels and a summary of completed work, this document presents information on waffle deck design, design of connections, redecking using waffle deck panels, and guidance on precast fabrication, construction, and installation of UHPC waffle deck panels.
