Research Interest

Professor Dong has carried out a wide range of teaching and research on space structures including thin-shell structures, space trusses, lattice shells and tensile structures over four decades.  

In the field of long-span space structures, Prof. Dong has  established and proposed many new theories and methods, including the sandwich  plate analogy method for space grid structures, the new method for the  triangular pyramid space grid of honeycomb pattern - the lower chord internal  force method, the practical application theory and calculation formulae for  composite space trusses, the design method for the load-carrying capacity of  welded hollow spherical joints under combined axial forces and bending moments,  and the quick calculation method for initial prestress distribution for cable  domes of Geiger- and Sunflower- type. Prof. Dong is the principal investigator  of four projects supported by the National Natural Science Foundation of China  including "Stability, ultimate load-bearing capacity and rational forms of space  grids", and the level of research is world advanced. Prof. Dong’s research  results have found successful applications in many important spatial structures,  such as Capital Sports Hall, Islamabad Gymnasium (Pakistan) and National  Swimming Center "Water Cube" for the 2008 Olympic Games. He has won 14 awards  for Progress in Science and Technology at national and provincial/ministerial  (First/Second Grade) levels. He is the founder and the editor-in-chief of the  Journal "Spatial Structures" (in Chinese). Prof. Dong has published over 200  technical papers and several books including "Analytical theory and calculation  method of space grid structures" and "Analysis, design and construction of new  space structures". Prof. Dong also provides strong technical supports on several  manufacturers of space structures including Zhejiang Southeast Space Frame  Company and Hangzhou Dadi Space Truss Company, which have been the most famous  companies in this field in China.
