According to the website of China Earthquake Administration on the 31st, he is a member of the Communist Party of China, an academician of the Chinese Academy of Sciences, an internationally renowned earthquake engineer, one of the pioneers of earthquake engineering in China, a member of the 6th, 7th, and 8th National Committee of the Chinese People’s Political Consultative Conference, and a geophysicist of the my country Earthquake Administration. Mr. Hu Yuxian, a researcher at the institute, died in Beijing at 20:46 on October 30, 2023 due to a sudden heart attack. He was 102 years old.

Mr. Hu Yuxian was born in Beijing in October 1922. Joined the Communist Party of China in November 1985. He graduated from the Department of Civil Engineering of Shanghai Jiao Tong University in 1946 with a bachelor’s degree, and graduated with a master’s degree (1949) and a doctorate (1952) from the University of Michigan in the United States. In 1955, he returned to China on the same ship as Qian Xuesen, and worked successively in the Institute of Civil Engineering and Architecture of the Chinese Academy of Sciences (now the Institute of Engineering Mechanics of the China Earthquake Administration) and the Institute of Geophysics of the China Earthquake Administration, and was once the director of the Institute of Engineering Mechanics. He was elected as an academician of the Chinese Academy of Sciences in 1991 and received the Ho Leung Ho Lee Science and Technology Progress Award in 1996. He has won the first and second prizes of the National Science and Technology Progress Award many times.
Mr. Hu Yuxian has always been at the forefront of earthquake engineering research. He was the first to propose combining geology and geophysics with earthquake engineering and social sciences, applying random vibration theory to the field of earthquake engineering, leading research on the impact of site conditions on earthquake vibrations and earthquake damage, and proposing methods for earthquake vibration estimation. Mapping method, he creatively proposed the comprehensive probability method for earthquake risk analysis, carried out in-depth research on urban earthquake damage prediction and disaster prevention and reduction, and presided over the preparation of my country’s earthquake parameter zoning map. The scientific and technological achievements provided scientific guidance for urban and engineering seismic fortification and disaster reduction. in accordance with.

Mr. Hu Yuxian attaches great importance to international academic exchanges and talent cultivation. He often participates in domestic and international academic activities and has visited the United States, Japan, Canada and other countries many times. He has served as the Chinese national representative of the World Earthquake Engineering Association, promoting the exchanges between China and the United States, Japan, and Academic exchange work in the earthquake engineering community in Europe and other countries.
Many theories and studies are of great significance
The official website of the Institute of Engineering Mechanics of the China Earthquake Administration shows that Hu Yuxian has been engaged in research work on earthquake engineering for a long time. Based on actual experience and theoretical analysis of earthquake sites, he proposed that the impact of site conditions should not be handled by intensity adjustment, but by two methods: foundation treatment and response spectrum adjustment. This result has been adopted by my country’s seismic codes since 1964. OEM high quality Customized OEM industrial metal supply near me
In the study of the impact of faults on seismic design, Hu Yuxian divided faults into seismogenic and non-seismic faults. On seismogenic faults, attention should be paid to the influence of dislocations without increasing the intensity; on non-seismic faults, only the influence of soil is considered. , without increasing the intensity. This result was adopted by my country’s seismic codes after 1974, providing convenience for engineering design.
Hu Yuxian combined my country’s deterministic earthquake prediction method with the internationally accepted probabilistic method of earthquake risk analysis, and considered the effects of various uncertainties to propose a comprehensive probabilistic method for earthquake risk estimation, which has been applied to my country’s new earthquake zoning map. In view of my country’s weak link in strong earthquake acceleration recording, in order to better utilize my country’s large amount of earthquake intensity data, Hu Yuxian conducted research on seismic motion estimation and proposed to add a third factor to the internationally commonly used intensity-acceleration conversion relationship. ——Magnitude or distance to indirectly consider the effects of other factors in the earthquake. This approach has been adopted by other scholars. OEM high quality Customized OEM industrial metal supply near me
At the age of 85, he still carries a backpack full of books and information to work
According to previous reports by China Science News, Hu Yuxian is energetic and extremely diligent in scientific research work and study. He spent almost all his available time studying. Study on holidays, study on business trips. Until he was 85 years old, he still carried a bag of books and information to work every day. When he was working, he was either reading or thinking attentively, checking carefully or writing with great concentration.
Hu Yuxian pays special attention to the development of new knowledge and new technologies. He consciously masters and utilizes any new knowledge and new technologies that can be used to expand and deepen research fields or improve work efficiency. Hu Yuxian would send his students abroad to learn new skills and use them for the development of this discipline after returning home. When he was in his seventies, he was still seriously studying computer operation, learning to make PPT, software drawing, programming, etc.
Hu Yuxian also paid great attention to efficiency when studying and was very practical. He never spent precious time reading idle books that were of great interest but of little use. The number of professional books and periodicals on earthquake resistance that he has read is almost the largest in the entire earthquake engineering community. Because he is well-read, he is well aware of the dynamics and development trends in earthquake engineering. OEM high quality Customized OEM industrial metal supply near me
When Hu Yuxian was nearly 80 years old, he even asked his leaders to go to the earthquake site. He said: “Don’t worry about my health. If I are not allowed to go to the site, my scientific research life will be over.” During the 2008 Wenchuan earthquake , Hu Yuxian, at the age of 86, appeared at the Wenchuan earthquake site to guide the work.
Over the years, Hu Yuxian has devoted himself to academic research and published more than 100 papers (parts). His representative works include: “Earthquake Engineering”, “ERRTHQUAKE ENGINEERING” (English version), etc. Among them, “Earthquake Engineering” won the fifth national award First Prize of Excellent Science and Technology Book Award. The scientific research projects he has undertaken have won the first prize of the National Science and Technology Progress Award once, the second prize of the National Science and Technology Progress Award and the provincial and ministerial level Science and Technology Progress Awards many times. Hu Yuxian is recognized as a front-line pioneer in the field of earthquake engineering, but he often calls himself an engineer. His indifference to fame and fortune and his simplicity are his true nature in life. OEM high quality Customized OEM industrial metal supply near me
