Earthquake Engineering Research Center (EERC)

    The Earthquake Engineering Research Center(EERC) was established in 1978, and named as the Department of Earthquake and Blasting Engineering before 1997.
    Recent researches in EERC cover the fundamental theories and application of new technologies in both engineering seismology and earthquake engineering in the field of civil engineering, with emphasis on hydraulic engineering as well as electrical energy engineering. These researches are, evaluation of the stability of tectonic zone, seismic zonation and seismic risk analysis, risk analysis of reservoir induced earthquake, planning of the array of remote-control seismometers, development of forecast and alarm system of reservoir induced earthquake, strong earthquake monitoring on large hydraulic project, field vibration monitoring, data bank of seismic records, dynamic diagnosis of large concrete dam, seismic resistance design of large hydraulic projects, vibration reduction of large scale structures, underground projects as well as high-rise buildings during earthquake, dynamic property of full scale concrete material of dam, and the software for static and dynamic analysis of dam including dynamic interaction of reservoir-foundation-structure and nonlinear behavior at the contact joints.

    A large scale shaking table of 6-freedom has been installed in EERC more than ten years ago, but it is still the best equipment for dynamic test of dam in the world, honored by Prof. R.W. Clough, because its size, maximum load, as well as the wide range in frequency. We also equipped with the devices of field test as well as strong motion seismometers, which are in operation in many hydraulic projects in China including Three Gorges Project. EERC has the national certificate of measurement, and national certificate for assessment of seismic risk. EERC is the chief editorial organization of the Code for Seismic Design of Hydraulic Structures, and the editorial organization of other 5 national standards.

    There are 23 staffs in EERC now, between them one academician of Chinese Academy of Engineering, two professors, ten senior engineers, and five engineers, four of them with Doctorial degree and six with Master degree. EERC provides position for post-doctor research.

    With the academic leadership of Houqun CHEN, the academician, EERC has completed many key projects of the state, National Science Foundation and Ministry of Central Government, providing very useful solutions related to earthquake engineering for the many large hydraulic projects. More than 16 research achievements have been granted State or Ministry Prize of Progress in Science and Technology, and more than 100 academic paper have been published in recent five years. Special softwares for static and dynamic analysis of gravity dam and arch dam have been developed.
    Several international joint researches have been carried out in EERC, with the specialists of United States. There are also academic exchange activities with the specialists of Japan and other contries.
