In short, Professor Liu Xiliang's main research projects in recent years include: new types and new joints of grid structure, calculation of various reticulated shell structures, assembled new grid structure, aluminum alloy spherical reticulated shell, and super-long-span (d & gtL00m) single-layer reticulated shell, such as integral cable dome, retractable structure, foldable spatial structure, etc., and have achieved gratifying results. Its award-winning projects include: 1982 "Research on calculation and jacking technology of four-support grid structure" and won the third prize of outstanding scientific research achievements of the Ministry of Construction. 1987 Code for Design of Steel Structures won the second prize of the State Planning Commission. Since 1980s, he has gone abroad for academic exchange four times. 1September 1982 to1September 1983, 10 paid a one-year academic visit to the steel structure research institute of Brunswick University of Technology in West Germany. From 65438 to 0984, he participated in the third international symposium on spatial structure of the University of Surrey, England, and read two papers. 65438-0985 lectured at Aachen Institute of Technology, West Germany. In June1987-February 1988, we went to Moi Sports Center, Nairobi, Kenya, to conduct scientific research experiments on the grid joints of the gymnasium. 1In September, 1993, he went to the Space Structure Research Center of the Department of Civil Engineering, University of Surrey, UK to chair the 4th International Conference on Space Structure, and read three papers. In recent years, he has participated in international conferences held in Singapore, Hong Kong and Japan. In recent ten years, he has published more than 40 papers in influential journals and important conferences at home and abroad. Among them, Traglastverschuche Zur lasteinleitungan I Formigen Geschweisten Biegererhorn Ohne Steifen (Stahlbau April 1988 Heft4 (Germany) J. Scheer, X.L. Liu, J. Falke, U. Peil) and others were published in important foreign journals. Published more than 10 papers at international conferences. He has published nearly 100 papers in domestic first-class and second-class magazines and in domestic professional conferences. There are 10 books edited by Professor Liu Xiliang: Plane Grid Structure Design (edited by 600,000 words, published by China Building Industry Press in l979, reprinted by 1985), Examples of Spatial Grid Structure (edited by 200,000 words, published by Tianjin Science and Technology Press 1982) and Grid. Coal Industry Press 1983) Calculation and Design of Grid Roof (main school, 72,000 words, published by Tianjin Science and Technology Press 1986), Manual of Engineering Mechanics (edited by 3.5 million words, published by Higher Education Press in l993), Design and Construction of Grid Structure (China Building Industry Press in l974

Professor Liu Xiliang's fruitful achievements have attracted the attention of Chinese and foreign counterparts. He not only made great contributions to scientific research and related projects, but also stayed in the front line of university teaching. He has taught undergraduate students such courses as steel structure, engineering structure, structural experiment and spatial grid structure. Postgraduate lectures on nonlinear analysis of advanced steel structures and spatial structures. He has taught undergraduate graduation design courses such as steel structure industrial workshop, radio mast tower, transmission line tower, TV tower and space grid structure. After he founded the entity of the power grid company, although he was also the general manager, he still adhered to the principle of combining scientific research, teaching and production, and integrated the new achievements of scientific research and engineering practice into the postgraduate training courses.
