Born in Prague on December 10, 1937, Ba?ant received the degree of Civil Engineer from the Czech Technical University (CTU) in Prague in 1960. While employed as Bridge Designer he earned in 1963 (as an external student) a PhD in engineering mechanics from the Czechoslovak Academy of Sciences; in 1966, he earned a postgraduate diploma in theoretical physics from Charles University, Prague. During 1964-67 he was research assistant professor at CTU working on fiber composites, and obtained the degree of Docent habilitatis in Concrete Structures from CTU in 1967. After postdoctoral fellowship at CEBTP Paris (1966-67) and Ford Foundation fellowship at University of Toronto (1967-68), he was during 1968-69 Associate Research Engineer at the University of California, Berkeley. In 1969 he joined Northwestern University as an Associate Professor and became Professor of Civil Engineering in 1973. During 1981-87 he served as the founding Director of Center for Geomaterials. During 1974-1994 he was simultaneously a Staff Consultant at Argonne National Laboratory. Since 1990, he has held the Walter P. Murphy Chair in Civil and Mechanical Engineering and Materials Science, and since 2002 simultaneously the chair of McCormick Institute Professor. Ba?ant served as the president of the Society of Engineering Science (1993); was the founding President (1991-93) of the International Association of Fracture Mechanics of Concrete Structures (IA-FRAMCOS); and the founding President (2001-2002) of the International Association of Concrete Creep and Durability Mechanics (IA-CONCREEP). He served as Division Director in IA-SMiRT (Struct. Mech. in Reactor Technology), as member of the US Nat. Comm. on Theor. and Applied Mech., and as editor-in-chief of Journal of Engrg. Mechanics of the Am. Soc. of Civil Engers. (ASCE). He has been the US regional editor of Int. J. of Fracture.
Research contributions and impact
Ba?ant, who is "generally regarded as the world leader in research on scaling in the mechanics of solids", is the author of six books dealing with concrete creep, stability of structures, fracture and size effect, inelastic analysis and scaling of structural strength. His size effect law (1984) is incorporated into shear design provisions of ACI Standard 318 (2019).
His size effect method for measuring fracture energy and process zone size in concrete became RILEM Standard Recommendation in 1990. His B3 and B4 prediction model for concrete creep and shrinkage became RILEM Standard Recommendation in 1995 and 2015.
His nonlinear diffusion model for moisture in concrete is part of European Model Code. His AAAM procedure is part of Standard recommendation of ACI and Model Code.
He is an Illinois registered Structural Engineer, and is one of the original top 100 ISI highly cited researchers in engineering (of all fields, worldwide). As of January 2019, his h-index is 123, i10-index is 616, and total citations nearly 68,000.
