报告题目:Fatigue of reinforced concrete bridge deck slabs – Monitoring and UHPFRC strengthening

主讲人:Eugen Brühwiler教授

时间:2017年7月25日(周二)下午 15:00-16:30

地点:公路学院一楼会议室

主讲人简介:Eugen Brühwiler教授毕业于瑞士苏黎世联邦理工学院(ETH),具有美国科罗拉多大学博士后经历。Eugen Brühwiler教授曾在瑞士联邦铁道部担任桥梁设计与施工管理工程师。1995年受聘为瑞士洛桑联邦理工学院(EPFL)教授,现任瑞士洛桑联邦理工学院(EPFL)土木、建筑与环境学院结构工程教授,结构工程研究所和结构安全与维护实验室主任。

报告摘要:The reinforced concrete slab of a 60 year-old steel – concrete composite bridge shows insufficient fatigue safety based on fatigue safety calculations using codes. Consequently, a monitoring system has been installed to measure fatigue stresses in steel rebars showing that the fatigue safety is sufficient. Based on this case study, some basic considerations regarding the fatigue strength of reinforced concrete are given. Finally, the effectiveness of strengthening of deck slabs using UHPFRC is presented and validated by means of research results.
