In 1992, Professor Shai received his Ph.D. in structural engineering from Hunan University. He has been researching of ultra-high performance concrete (UHPC) bridges over 10 years, and is committed to solving problems of conventional bridges with novel UHPC structures. Prof. Xudong Shao's team developed the core technology of strengthening orthotropic steel deck (OSD) with UHPC, which successfully solved the worldwide problems of fatigue cracking of steel bridge deck and damage to the pavement layer. This achievement has been applied to more than 100 bridges in 26 provinces in China, including Sutong Yangtze River Highway Bridge (in Shanghai), Haiwen Bridge (in Hainan), Hangrui Dongting Bridge (in Hunan) and other long-span bridges. In addition, multiple types of UHPC bridge decks, prefabricated UHPC bridges and long-span UHPC box girder bridges have been developed and successfully applied, which effectively solved many common problems of concrete bridge, such as heavy self-weight, many diseases and large car
