Biography

Shmukler was born on June 26, 1946, in the city of Krasnoyarsk, USSR. His family moved to the city of Kharkiv in 1949. His father, Samuel I. Shmukler was a mechanical engineer and worked all his life in the construction and mounting trust No. 86 as a chief mechanic. His mother, Shklovskaya Asya Abramovna was a chemist and the head of the laboratory at the pharmaceutical institute. In 1964 he entered the Kharkiv Institute of Civil Engineering (now – Kharkiv National University of Building and Architecture) on faculty «Industrial and Civil Engineering», from which he graduated in 1969. After graduating in civil engineering from 1969 to 1986, he worked in the «Kharkovproekt» consistently occupying positions from the engineer to the chief of the department, and from 1986 to 1990 – in the «Ukrgorstroyproekt», where he occupied positions from the head of technical department to the deputy chief engineer of the institute. In 1977 he defended the PhD thesis, and in 1997 – thesis for the degree of the doctor of technical sciences. Since 1990 Shmukler has been working in O. M. Beketov National University of Urban Economy (ex – Kharkiv National Academy of Municipal Economy), consistently occupying positions: the professor of building structures, and since 2012 – the chief of building structures department.

Work in state design institutes

After graduating from the Kharkiv Institute of Civil Engineering (now – Kharkiv National University of Building and Architecture), Shmukler from 1969 to 1990 worked in the research and design institutes, «Kharkovproekt» (1969–1986), «Ukrgorstroyproekt» (1986–1990), where he occupied the positions from the head of the technical department to the deputy chief engineer of the institute. In «Kharkovproekt» period, he created one of the first in Ukraine the computation center and computer-aided design of industrial and civil structures. Under his leadership and with direct participation a number of CAD software systems were created. The results of these developments were the basis of his dissertation for the degree of candidate of technical sciences «Research work flat concrete casings». The work suggested and developed new methods of accounting for physical and geometrical nonlinearities in solving the problems of static stability of membranes covering. Also, in these years, Shmukler co-authored a series of CJC (Complex Kharkiv Series) for the construction of large sixteen-residential buildings and was one of the organizers of a network of data centers roses State Construction Committee of Ukraine. Over the years of work in the GUI «Ukrgorstroyproekt», Shmukler was one of the pioneers in the creation and development of youth and housing construction in Ukraine. After the earthquake in Armenia he took an active part in the reconstruction of housing, that had welfare and cultural purposes. He was one of the first engaged in the implementation of the industrial facilities of reinforced concrete and metal spatial structures in buildings and structures of the country.

Scientific activity

Shmukler's scientific interests are associated with the theory of structural systems, information technology for calculation and design of structures, methods of their optimization and rationalization. His main works in this area include: integrated gradient method for finding the global extremum of functionals on many variables; method for solving multiobjective optimization problems; overdetermined contour collocation method for solving boundary problems in the theory of plates and shells; compilation methods for solving nonlinear problems of the theory of constructions. A cycle of his work devoted to the creation of direct design methods, well-founded principles of new energy, is the basis of the formation of constructions with a simple external and complex internal geometry. Based on them, the following were created and implemented: architectural construction systems RAMPA, IKAR, DOBOL, intended for housing and civil engineering; a family of gantry and bridge cranes up to 800 tons, etc. Architectural construction system RAMPA (abbreviation: panel frame) is an alternative to panel housing and is intended for the design and construction of five to six story residential buildings, hotel complexes, facilities of social and cultural purpose, health protection facilities, three to four story garage parking for automobile motor transport, cottages, health resorts and other facilities of housing and civil purposes. It was built on the principle of the organic compound of the best qualities of carcass and frameless systems (Fig. 1). The basis of the architectural and construction system RAMPA is a catalogue of its products made of precast reinforced concrete. At the same time, the catalogue has a limited set of elements that generate an infinitely large variability of their combination into dimensional compositions. These elements include flat panel frames and floor panels. Panels of slab together with the frames are the basic framework elements, which are being built according to the principle of children's erector set. Four orthogonally jointed frames and two panels of slab create a «cube», which allows free jointing with other structural cells. A cellular regular or irregular, but nevertheless, fractal structure resulting from joining of the «cubes», is in some sense similar to the bionic carrier frames. At the same time, the use of conventional or lightweight reinforced concrete is limited only by bearing elements. The main size of panel frames – 3.6х3.3(h) m, panels of slab – 3.6х3.6 m, 1.8х7.2 m. The weight of panel frames does not exceed 800 kg, weight of panels of slab has a weight of 2 to 3.5 t. RAMPA system is a problem-oriented system, i.e. a system having a clear applied focus (Fig. 2).

In 1995, Shmukler was awarded the title of laureate of the State Prize of Ukraine in the field of architecture for the development, research and introduction of a new architectural and construction system RAMPA for housing and civil engineering. In 1997, Shmukler defended his doctoral dissertation on the topic: «Dimensional reinforced concrete frame systems of multi-criteria compliance». Within the scope of this thesis he defended 37 scientific papers and 24 patents, being the scientific basis of solving the problem of creation of a system of buildings in compliance with modern conditions with maximum use of the existing base of construction industry. The methodology proposed is the result of a specially constructed modification of the theory of direct structural design, which includes mathematical modeling of these systems, rationalization of their parameters while regulating stress-strain state. On the basis of the approach problem-oriented architectural and construction systems of residential and public buildings distinguished by high competitiveness were created. A wide range of theoretical research designs were carried out, which resulted in the creation of methods, algorithms and programs to solve complex problems in the theory of non-linear structures, allowing to minimize the processing time. The program products included in calculating complex MIRAZH were developed. The theoretical results were tested by setting up field experiments on structures with optimized parameters. Carrying out experiments became possible with adapting and refining the technical and program means of the automated system of scientific achievements. Industrial introduction of the proposed structures, methods of their design, production, transportation and installation, providing substantial saving of resources was carried out. Environmental and economic characteristics of the installations were improved (Fig. A, B, C, D, E, F, G).

On the basis of Shmukler's scientific papers, the following was created and implemented: noise and vibration damping system for mobile power stations, functioning on the basis of secondary use of aircraft jet engines; chambers for welding in high vacuum; dimensional metallic and composite structures of slabs and covers, etc. (Fig. 3, 4).

Shmukler is the author of the hydraulic method of experimental study of designs. This method is widely used for field, laboratory acceptance testing of designs, both for those constructed and in the process of construction (Fig. 5).

Shmukler participated in the design and construction of unique facilities, such as: library complex of the NTU «KhPI» (Kharkiv); reconstruction of the ground control complex of the national satellite communication system in Crimea; complex of 28-story residential buildings in Kharkiv; logistics center «Maxus»; entertainment complex «Misto»; exposition center in Constitution Square in Kharkiv, large span constructions of civil and industrial structures; multi-storey structures made of reinforced concrete with a wide grid of columns (Fig.6).

He took part in the reconstruction of architectural monuments of the constructionism period: the 52th liaison office (Kharkiv); the building of Gosprom (Kharkiv), etc. Research and development activities, which are conducted under the direction of Shmukler, dedicated to the restoration of buildings and structures affected by man-made disasters, are the practical basis of the full range of works in the conditions of force majeure (Fig. 7).

In 1999, he was elected as the member of the Ukrainian Academy of Construction. Shmukler's scientific achievements were marked with state awards: for the organization, implementation and development of the youth construction in Ukraine – 40 Years of Youth Residential Complex Movement Medal (2011); for his outstanding contribution to the development of science, technology and engineering in Ukraine – Silver Medal of the Academy of Construction of Ukraine (2013) and Gold Medal of A. N. Podgorny of the Engineering Academy of Ukraine (2014). In 2015 he was awarded with the honorary title «Honored Worker of Science and Technology of Ukraine». References to Shmukler's works can be found in a number of books, articles, dissertations, research reports of other authors. The constructions developed by him are used and applied in a number of projected and constructed facilities.
