Prof. Eng. Vladimír Křístek, DrSc., Dr. h. c., FEng.
(1938-2020)

pdf Long Performance of Time Structural Prestressed Bridges - a presentation by Prof. Eng. Vladimir Křístek

On September 9, 2020 in Prague Prof. Eng. Vladimír Křístek, DrSc., Dr. h. c., FEng, suddenly left us at age of 82. Born on Oktober 15, 1938 in Prague, he is professor since 1977 in the Department of Reinforced Concrete and Masonry Structures at the Faculty of Technical Sciences in Prague, Czech Republic. Two-time winner of the State Prize of Czechoslovakia and two-time winner of the Czech Academy of Sciences for extremely high contributions in the field of research. Member of the Presidium of the Academy of Engineering of the Czech Republic. Chairman of the attestation commission for selection of doctoral students. He has won over 100 international and national research grants from 1970 to the present. Prof. DrSc. Eng. Vladimir Krsistek is a world-renowned expert in the field of stress and strain of reinforced concrete bridges and multi-storey buildings, taking into account the influence of the rheological properties of concrete. He gives lectures on reinforced concrete structures and bridges, stability of building structures, taking into account the influence of creep and drying of concrete and the method of the finite strips. Invited as a guest lecturer in the USA, Germany, England, Belgium, Finland, Italy, Greece. He is the author of 14 monographs and over 750 scientific publications in peer-reviewed international journals. Under his leadership, a total of twenty-four researchers defended their doctoral dissertations. Expert and designer of a number of complex with large openings bridges with box-shaped cross sections. Licensed civil engineer and consultant for a large number of reinforced concrete structures and facilities in the Czech Republic and abroad.
