The Department’s Mission

Department History

1922

The origins of the Department date back to the establishment of the University of Lithuania in 1922. The Department of Bridges was entrusted with teaching the design of masonry, timber, steel, and reinforced concrete bridges, including bridge design projects. At that time, structural engineering and bridge engineering were regarded as a single discipline.

1940

The Department of Bridges was reorganized into the Department of Bridges and Steel Structures within the Faculty of Civil Engineering. The department was headed by Associate Professor J. Kuodis. He was the first Lithuanian reinforced concrete specialist to defend a Doctor of Technical Sciences dissertation, which he completed in 1936 at the Higher Technical School in Vienna.

1941

In the autumn semester, the Department of Bridges and Steel Structures was renamed the Department of Bridges and Structures.

1944

The Department of Reinforced Concrete Structures and Bridges was established within the Faculty of Civil Engineering, headed by Senior Lecturer A. Rozenbliumas. In 1958, he was awarded the State Prize in Science and Technology for his work Prefabricated Reinforced Concrete or Armosilicate Arches (Frame Trusses) for Building Roof Structures.

1956

At the Kaunas Polytechnic Institute (KPI) Evening Division in Vilnius, established in 1956 and transformed into the KPI Vilnius Branch in 1961, reinforced concrete courses were taught by lecturers from the Department of Civil Engineering, headed by Associate Professor V. Kriščiūnas. Reinforced concrete courses were taught by A. Kudzys, while foundation engineering was taught by V. Pranaitis.

1965

On 1 September, the Department of Civil Engineering was divided into two departments: the Department of Urban Construction and the Department of Structural Engineering. Associate Professor Antanas Kudzys was appointed Head of the Department of Structural Engineering.

1966

G. Marčiukaitis, P. Pukelis, and their colleagues received the Lithuanian State Prize in Science and Technology for their work Research on Prestressed Reinforced Concrete Structures.

1967

A. Kudzys defended his Habilitated Doctor dissertation and became the first professor in Lithuania to conduct research in reinforced concrete mechanics, as well as the first professor of the Vilnius Civil Engineering Institute.

1972

The Department of Structural Engineering was renamed the Department of Reinforced Concrete Structures, headed by Professor A. Kudzys until 1992. This enabled the further development of research in concrete and reinforced concrete. From 1967 to 1995, on the initiative of the department’s researchers, the continuing scientific publication Reinforced Concrete Structures was published, with a total of 17 volumes.

The first research space was set up in the basement, while precast floor slabs were tested in the courtyard, marking the department’s first experimental research project.

1974

Professor A. Kudzys was awarded the State Prize in Science and Technology for his series of works Theory and Practice of Circular Reinforced Concrete Structures.

1979

The Structural Engineering Laboratory, operating within the Department of Reinforced Concrete Structures, moved into a newly constructed laboratory building at Saulėtekio Ave. 11. This significantly improved the conditions for scientific research. The laboratory was equipped with state-of-the-art equipment for testing concrete, reinforced concrete, and masonry structures.

1980

Professor A. Kudzys was elected a Corresponding Member of the Lithuanian Academy of Sciences.

1982

A computing unit of the Vilnius Civil Engineering Institute Computer Centre was established within the Structural Engineering Laboratory to digitalize structural testing. Dedicated exclusively to the laboratory, the unit was equipped with two SM-578 computers connected to three mobile data acquisition systems. This substantially increased the speed and accuracy of data collection and facilitated the analysis of research results.

A. Kudzys, R. Vadlūga, V. Jokūbaitis, and J. Kivilša received the State Prize in Science and Technology for the textbook Reinforced Concrete Structures.

1990

Thesis abstract (EN)

The final Master’s thesis examines the possibilities for automating design clash detection processes by applying artificial intelligence (AI) methods in a BIM environment. The aim is to assess how AI can contribute to the digitization of design processes, increased efficiency and the growth of data value. The objective of this work is to analyze the literature, documents and technological solutions applied to automated clash detection in BIM projects using AI technologies, with the aim of increasing detection accuracy, reducing time costs, and improving the efficiency of the design process. The analysis highlighted the importance of information integrity, structuring and effective data management, as well as the growing role of advanced technologies in this field. This study empirically investigates the potential applications of AI technologies in the specific context of BIM clash detection, evaluating their applicability, resource requirements and effectiveness. It was found that AI methods effectively solve mathematical and geometric tasks, but high-quality and consistent data preparation is essential for semantic data analysis. The importance of socio-technical factors-specialists’ competencies, trust in technology and organizational readiness - also became apparent. To address the research problem, an experimental study was conducted, during which an AI model was developed and tested by analyzing different combinations of features and evaluating the results. The study identified key challenges, areas for improvement, and prospects for AI application in the field of BIM clash detection. The thesis consists of an introduction, analytical-theoretical, methodological, and research-analytical sections, conclusions and recommendations, and appendices. The scope of the work, excluding appendices, is 66 pages, 6 illustrations, 15 tables and 82 bibliographic sources.

Thesis abstract (LT)

Profesinis bakalauro baigiamasis darbas susideda iš architektūrinės, konstrukcinės ir technologinės dalių, skirtų naujam 8 aukštų studentų bendrabučiui Varšuvoje, Lenkijoje. Pastate numatytos gyvenamosios, viešosios ir techninės funkcijos: 1-ajame aukšte suprojektuotos įėjimo, bendrosios ir techninės patalpos; 2–8 aukštuose – gyvenamieji kambariai ir paslaugų zonos. Vertikalų ryšį užtikrina dvi laiptinės ir du liftai. Ant stogo įrengtos inžinerinės ir liftų mašinų patalpos. Architektūrinėje dalyje pateikti stogo, išorinių sienų ir pirmojo aukšto grindų ant grunto šilumos izoliacijos skaičiavimai Varšuvos klimato sąlygoms, užtikrinant, kad šilumos perdavimo koeficientai ($U$ vertės) atitiktų Lenkijos WT 2021 statybos reglamento reikalavimus. Konstrukcinis sprendimas – monolitinis gelžbetoninis karkasas (beveisė perdangos ir kolonų sistema). Pastato erdvinį standumą ir stabilumą nuo vėjo apkrovų užtikrina dvi laiptinės ir liftų šachtos, veikiančios kaip standumo šerdys. Monolitinės perdangos veikia kaip standžios horizontalios diafragmos. 3D struktūrinis modelis sukurtas „SCIA Engineer“ programine įranga pagal Eurokodus (EN 1990–EN 1998). Atlikti tipinės perdangos (ULS, SLS, pleišėjimo, prastūmimo), kolonos (gniuždymo su ekscentritetu) ir gręžtinių polių pamatų grupės skaičiavimai. Technologinėje dalyje suorganizuotas monolithinių konstrukcijų įrengimas, parengta technologinė kortelė klojinių, armatūros ir betonavimo darbams. Parinkti ištekliai (bokštinis kranas, betono siurblys, automobilių maišyklės), numatyta kokybės kontrolė, saugos priemonės, darbo sąnaudos ir techniniai-ekonominiai rodikliai. Darbą sudaro 8 dalys: įvadas, bendrieji duomenys, architektūrinė, konstrukcinė, technologinė dalys, darbuotojų sauga, aplinkosauga, sąmatos skaičiavimai ir išvados.
