About the Department
Department History
1922-03-24
After the Statute of the University of Lithuania was approved, 17 departments were established within the Faculty of Technology. At that time, there were no separate departments for structural engineering, and structural design was considered part of bridge engineering. The closest related unit was the Department of Bridges, which was responsible for teaching stone, wooden, steel, and reinforced concrete bridges.
1922-03-24
The Department of Bridges was established. The head of the department until 1940 was Ord Prof Silvestras Grinkevičius.
1923-02-01
Privatdozent Pranciškus Markūnas joined the Department of Bridges. He taught reinforced concrete, supervised design projects, and designed 19 reinforced concrete bridges and 16 buildings, including four churches.
1928-10-01
J. Gabrys was appointed Junior Assistant.
1930-09-01
J. Gabrys was promoted to Senior Assistant. He supervised the design of bridges and reinforced concrete structures, taught culvert design, and authored the textbooks “Culverts” (1930) and “Reinforced Concrete and Concrete Bridges” (1931).
1938 m.
J. Gabrys defended his dissertation “Concrete and Reinforced Concrete Arches” at the Faculty of Engineering of the University of Latvia.
1940-07-29

Baigiamajame magistro darbe atlikta stiprinamos gelžbetoninės sijos statmenojo pjūvio laikomosios galios analizė, įvertinant armatūros koroziją ir lyginant skirtingus skaičiavimo bei analizės metodus. Darbas susideda iš analitinės – metodinės ir eksperimentinės – tiriamosios dalių.
Analitinėje – metodinėje dalyje išanalizuotas korozijos poveikis sijos elementui, apžvelgti konstrukcijų stiprinimo būdai bei išnagrinėtos sustiprintų sijų laikomosios galios skaičiavimo metodikos pagal LST EN 1992-1-1, Malganovo metodiką bei tikimybių teorijos tiesioginį informacinį-statistinį (TIS) metodą. Taip pat išnagrinėtos analitinės bei skaitinės netiesinės analizės metodikos ATENA aplinkoje bei pagal EC2, sudarant apkrovos ir įlinkių priklausomybės kreives.
Eksperimentinėje – tiriamoje dalyje atlikti sijos, stiprinamos gelžbetonine apkaba arba papildomu gelžbetonio sluoksniu, analitiniai laikomosios galios skaičiavimai. Jie atlikti vertinant dvi sąlygas: kai pasiekiamas 1 mm korozijos gylis ir kai koroduota armatūra nebevertinama. Atlikus parametrų analizę, nustatyta stiprinamojo sluoksnio storio ir papildomos armatūros skersmens įtaka laikomosios galios atsargai. Sijų elgsenai nustatyti sudarytas skaitinis modelis programa ATENA. Tiek analitiniuose skaičiavimuose, tiek skaitiniame modeliavime konstrukcijų darbas vertintas darant idealiai standaus mazgo prielaidą. Galiausiai, analitinių skaičiavimų ir skaitinio modeliavimo rezultatams įvertinti, atliktas keturių dvisluoksnių gelžbetoninių sijų kontrolinis eksperimentinis bandymas. Nors eksperimento tikslas buvo pasiekti idealiai standžią jungtį, realios sijos suiro dėl kontaktinėje zonoje įvykusio šlyties poveikio bei sluoksnių atsiskyrimo. Remiantis gautais rezultatais, darbe pateikiama rekomendacija dėl papildomų konstrukcinių priemonių, būtinų projektiniam jungties standumui užtikrinti.

The master’s thesis analyzes the normal section load-bearing capacity of a strengthened reinforced concrete beam, considering reinforcement corrosion and comparing different calculation and analysis methods. The work consists of analytical–methodological and experimental–research parts.
The analytical–methodological part analyzes corrosion effects on the beam, reviews strengthening methods, and examines capacity calculation methodologies according to LST EN 1992-1-1, Malganov’s methodology, and the probability theory-based direct information-statistical (DIS) method. Analytical and numerical non-linear analysis methodologies within the ATENA environment and according to EC2 are also examined, establishing load-deflection curves.
The experimental–research part presents analytical capacity calculations for a beam strengthened with a reinforced concrete jacket or an additional concrete layer, evaluating a 1 mm corrosion depth and neglected corroded reinforcement. Parametric analysis determined the influence of strengthening layer thickness and additional reinforcement diameter on the capacity margin. To evaluate beam behavior, a numerical model was developed using ATENA software. Both analytical and numerical methods assumed an ideally rigid joint. Finally, a control experimental test of four double-layer reinforced concrete beams was conducted to evaluate the results. Although aiming for an ideally rigid joint, the full-scale beams failed due to contact zone shear effects and layer delamination. Based on the results, additional structural measures are recommended to ensure the design stiffness of the joint.
The thesis includes an introduction, two main parts with subsections, conclusions, and references. Scope: 130 p. (excl. appendices), 69 illus., 30 tabs., 20 sources, 1 appendix.

Planavimo etape dažnai reikia rengti ar koreguoti teritorijų planavimo dokumentus, o naudojami tradiciniai metodai apsunkina kaštų, laiko ir žmogiškųjų išteklių valdymą, mažina sprendimų pagrįstumą bei informacijos srautų tęstinumą tarp etapų.
Darbo tikslas – atlikti statinio gyvavimo ciklo veiklų ir statinio informacinio modeliavimo taikymo atvejų ryšių analizę, atskleidžiant BIM taikymo atvejų ir BIM taikymo būdų integruotas sąsajas planavimo ir projektavimo etapuose, taikant statinio informacinio modeliavimo metodologiją.
Darbe atlikta literatūros šaltinių ir normatyvinių teisės aktų analizė, procesų modeliavimas ir skaitmeninis eksperimentas. Darbe pasiūlytas BIM taikymo atvejų ir būdų sąsajų rinkinio modelis, paremtas LR statybos teisės aktuose apibrėžtais projekto vykdymo procesais ir veiklomis planavimo ir projektavimo etapuose. Šis modelis pritaikomas realiose situacijose, leidžia sklandžiau pereiti iš planavimo į projektavimo etapą. Rezultatai rodo, kad sistemingas BIM metodologijos naudojimas jau planavimo stadijoje, pradedant nuo teritorijų planavimo dokumentų rengimo, padeda optimizuoti sprendimų priėmimą, mažina rizikas ir leidžia automatizuoti projekto pritarimų ir statybos leidimų išdavimo procesus.
Darbo pabaigoje pateikiamos išvados bei praktinės rekomendacijos dėl BIM metodologijos taikymo statybos projektuose planavimo ir projektavimo etapuose.
Darbą sudaro 6 dalys: įvadas, literatūros analizė, siūlomo modelio analizė, skaitmeninis eksperimentas, išvados ir siūlymai, literatūros sąrašas.
Darbo apimtis – 99 p. teksto be priedų, 25 iliustr., 16 lent., 46 bibliografiniai šaltiniai.

Thesis abstract (EN)
The Building Information Modelling (BIM) methodology is widely applied in the design, construction, and operation stages, however, the planning stage often remains insufficiently integrated into BIM processes. During the planning stage, it is often necessary to prepare or revise territorial planning documents, and the use of traditional methods complicates the management of costs, time, and human resources, reduces the rationality of decision-making, and disrupts the continuity of information flows between stages.
The aim of this thesis is to analyse the relationships between Building Life Cycle activities and BIM Uses, revealing the integrated connections between BIM Uses and BIM Use Methods in the planning and design stages through the application of BIM methodology.
The thesis includes the analysis of literature sources and normative legal acts, process modelling, and a digital experiment. A model of the integrated set of BIM Uses and Use Methods is proposed, based on the project implementation processes and activities defined in Lithuanian construction legislation for the planning and design stages. This model can be applied in real-life situations and enables a smoother transition from the planning to the design stage. The results show that the systematic use of BIM methodology already at the planning stage—starting with the preparation of territorial planning documents—helps optimise decision-making, reduce risks, and allows for the automation of project approvals and building permit procedures.
The thesis concludes with findings and practical recommendations for the application of BIM methodology in construction projects during the planning and design stages.
The thesis consists of six parts: introduction, literature review, analysis of the proposed model, digital experiment, conclusions and recommendations, and references.
The total length of the thesis is 99 pages (excluding appendices), including 25 figures, 16 tables, and 46 bibliographic sources.
The appendices are attached separately.

Šiame baigiamajame darbe nagrinėjamas Administracinio pastato su gyvenamosiomis patalpomis projektavimas ir analizė, esantis Visagine, Lietuvoje (koordinatės: 55°36'00.2"N 26°25'01.6"E). Tai trijų aukštų mišrios paskirties pastatas, kuriame pirmame aukšte įrengtos komercinės ir administracinės patalpos, o viršutiniuose aukštuose – gyvenamieji butai.
Architektūriniu požiūriu, projekte pabrėžiama funkcionalumas, prieinamumas ir tvarumas. Pirmame aukšte yra administraciniai biurai, konferencijų salė, bendro naudojimo patalpos bei gerai suplanuotos vertikaliosios komunikacijos sistemos, tokios kaip laiptinės ir liftas. Viršutiniuose aukštuose įrengti šiuolaikiški butai bei bendros erdvės, sudarančios patogią gyvenamąją aplinką.
Konstrukciniu požiūriu, pastate naudojamas monolitinis gelžbetonis, o kolonos, perdangos ir sienos liejamos vietoje. Ši konstrukcija suprojektuota taip, kad užtikrintų ilgaamžiškumą bei atsparumą aplinkos poveikiui, tokiam kaip vėjas ar sniegas, būdingi šiam regionui. Projekte taip pat integruotos priešgaisrinės saugos priemonės ir avariniai evakuacijos keliai.
Apskritai, šis projektas parodo architektūrinių ir konstrukcinių sprendimų visapusišką integraciją, sukuriant techniškai patikimą ir naudotojui pritaikytą pastatą, tinkantį mišrios paskirties plėtrai šiuolaikinėje miesto aplinkoje.

This thesis focuses on the design and analysis of an Administrative Building with Residential Premises located in Visaginas, Lithuania (coordinates: 55°36'00.2"N 26°25'01.6"E). The structure is a three-story mixed-use building, combining commercial/administrative functions on the ground floor with residential apartments on the upper levels.
Architecturally, the project emphasizes functionality, accessibility, and sustainability. The ground floor includes administrative offices, a conference room, shared facilities, and well-organized vertical circulation systems, such as staircases and an elevator. The upper floors house modern apartments and communal spaces, providing a comfortable living environment.
Structurally, the building employs monolithic reinforced concrete, with in-situ cast columns, slabs, and walls, designed to ensure durability and resistance to environmental loads like wind and snow, common in the region. The design also integrates fire safety, emergency escape routes,
Overall, this project demonstrates a holistic integration of architectural and structural disciplines, delivering a building that is both technically robust and user-centered, suitable for mixed-use development in a modern urban setting.
