Syminskyy Kostantin (1879-1932) - Academician of the USSR (1926), Professor, Head Strength of Materials Department (1911-1932), Vice-President of the USSR Academy of Sciences (1931-1932). In 1907 he graduated from Kyiv Polytechnic Institute, Department of bridge construction, led by E.A. Paton, from 1914 - Professor. During 1907-1932 he worked as a teacher of the Kiev Polytechnic Institute. In 1920-1921 - Dean of the Civil Engineering Department, 1924-1926 - Vice Rector for educational work. At the same time he worked in 1921-1932 Director of the Institute of Technical Mechanics, USSR (now the Institute of Mechanics of NAS of Ukraine named after S.Timoshenko), in 1929-1932 - the director of the Kiev branch of the Building Research Institute. He carried out the educational and methodical work of the University of Kiev (1918-1919), the Institute of National Economy (1922-1923), the Art Institute (1927) and Polytechnic Institute of Odessa (1918-1919). In 1914 he defended his thesis "On the formation of spatial trusses for bridges" for the title of associate of structural mechanics. After defending his dissertation he was elected Professor of strength of materials and the head of the mechanical laboratory of the Kiev Polytechnic Institute.
His main scientific works were devoted to the problem of metal fatigue in bridges, wood, research of new types of wooden structures, the study of strength characteristics of the stone building materials. He was the first to propose new methods of calculating and creating spatial rod trusses for railway bridges, explored new types of wooden spatial structures for industrial and civil construction, developed the theory of the strength of granite. He was the author of the science to test the strength of bridges and structures. Brilliant in form and content his lectures on strength of materials have created deserved fame to the outstanding teacher. In addition to teaching and research activities he conducted large organizational work. He took an active part in the reorganization of high school, the general reform of the Kiev Polytechnic Institute (1920), was a member of the State Committee for Science and Methodology USSR.
He was awarded the Order of St. Stanislaus III. (1914).
He authored 73 scientific papers, including 33 monographs and scientific articles, 23 books and manuals, 17 methodological articles. Major works are: "Structural Mechanics. Systems with extra unknowns "(1928)," Rigid beams "(1930)," Technical Mechanics "(1931)," The course of static structures "(1931)," Strength of Materials "(1924),"Wooden bridges "(1915 together with Paton).
