This book presents the latest practices in high-speed railway suspension bridge design, covering site selection, bridge type and span layout, loading assumptions and load combinations, structural stiffness, structural components, expansion joints, wind resistance, and seismic analysis. It also shares insights on the wind-train-track-bridge interaction, wind and seismic analysis and design, and provides solutions for construction and maintenance. Wufengshan Yangtze River Bridge was taken as an example to introduce the key technologies of long-span high-speed railway suspension bridges in research, design, construction, and maintenance comprehensively.
This is an ideal guideline and reference book for bridge engineers and consultants engaged in research, design, construction, and maintenance of suspension bridges. It can also be adopted as a textbook for teachers and students of bridge engineering in the teaching of suspension bridges.

Gongyi Xu was graduated from the School of Civil Engineering at Southwest Jiaotong University in 1984. As the chief engineer, He has led and completed the design of over 30 major bridges, among which typical representatives are Shantou Bay Bridge, Xiwan Bridge in Macau, Xiling Yangtze River Bridge, Taizhou Yangtze River Bridge, Yangsigang Yangtze River bridge, and Wufengshan Yangtze River Bridge, He was elected National Design Master in 2006 and won the first Chinese National Outstanding Engineer Award in 2014, as the only one in bridge engineering nationwide in China. He was the sole winner of ICEs International Medal in 2018, recognized for his outstanding achievements in long span suspension bridge designs. In 2018, he was awarded the John A. Roebling Medal and recognized for lifetime contribution on the bridge engineering worldwide. He is the technological pioneer of China's large-span modern suspension bridges, making unremitting efforts and outstanding contributions to technological progress. It is precisely based on his contributions that the large-scale construction of large-span high-speed railway suspension bridges in China has solved the key problem which restricts the improvement of the high-speed railway network.
