Zeng Qingyuan, Academician of the Chinese Academy of Engineering
Zeng Qingyuan, male, was born in Taihe County, Jiangxi Province in October 1925. In July 1950, he graduated from the Department of Civil Engineering at Nanchang University; years later, he joined the postgraduate program in steel work of the Department of Civil Engineering at Tsinghua University and finished the program in July 1956. In December 1985, on the special approval of the Education Commission of Hunan Province, he was titled as professor; In September 1986, he was approved by the Academic Degrees Committee of the State Council as doctoral supervisor in Bridge and Tunnel Engineering at Changsha Railway University. In November 1999 he was elected as Academician of Chinese Academy of Engineering.
His main research achievements:
Proposing the Principle of Total Potential Energy with Stationary Value in Elastic System Dynamics, the concept of total potential energy distinguishing the stability of motion of a system and the “Set-in-right-position” rule for formulating matrixes;
Setting up an analysis theory of lateral vibration energy for train-bridge time-varying system, which enables the analysis on the lateral rigidity for the railways and bridges including Jiujiang Bridge and Wuhu Yangtze River Bridge and brought him the second prize of the Science and Technology Progress Award of Ministry of Railway in 1998 and the third prize of the National Science and Technology Progress Award in 1999.
Building a local-overall interactive buckling ultimate carrying capacity analysis on bridge structures, which is applied for the ultimate carrying capacity analysis of such bridges as the three-tower cable-stayed bridge over Dongting Lake in Yueyang.
Establishing an analysis theory of lateral vibration energy for train-bridge time-varying system and the analysis theory of lateral dynamics stability for CWRs (Continuous Welded Rail).
Creating a train derailment analysis theory, which is an internationally unique breakthrough for the century-lasting knot for train derailment analysis and controls effectively the train derailment of trains on rails and bridges; this theory has earned for him the first prize of Hunan Science and Technology Progress Award in 2006.
Professor Zeng has 16 master students and over 30 doctoral students. Altogether, there are over 100 papers under his authorship in addition to 5 books, i.e. Theory and application of train-bridge time-variant system vibration analysis, Analysis Theory and Application of Train Derailment, Steel Struts Carrying Capacity at Stability Limit, (ranked second), Structural Dynamics and Structural Stability Calculation (the last two are textbooks). Apart from the two third prizes of National Science and Technology Progress Award, two second prizes of the Science and Technology Progress Award of Ministry of Railway, one first prize of Hunan Science and Technology Progress Award, the third Zhan Tianyou Achievement Award, the seventh Zhan Tianyou Railway Science and Technology Award, he is conferred with the title of National Excellent Teacher by the Ministry of Education and Ministry of Personnel of China.
