A new approach in bond modelling of reinforced concrete members
(Mechanika'2015 : proceedings of the 20th international scientific conference, 23, 24 April, 2015, Kaunas University of Technology, Lithuania, 2015)Present paper presents an alternative approach for bond, cracking and deformation modelling of RC structures. It is based on the average cracking and deformation behaviour of RC elements rather than bond - slip relationship ... -
Absolute and relative evaluation of socio-economic objects based on multiple criteria decision making methods
(Inžinerinė ekonomika = Engineering economics, 2014)The multiple criteria decision making (MCDM) methodology implies relative quantitative evaluation of several compared alternatives relative to the chosen objective of evaluation. There is a compulsory requirement for making ... -
Aspects of absolute evaluation of financial stability state of commercial banks
(The 4th World Sustainability Forum, 1-30 November 2014 : conference proceedings paper, 2014)Concern on financial stability of commercial banks is an ongoing issue, requiring permanent reviewing of regulatory frameworks and developing new approaches. Currently static regulatory methodologies are prevailing, which ... -
Aнализ деформаций железобетонных растягиваемых элементов, внешне усиленных дисперсионно-армированными полимерными листами
(Механика композитных материалов, 2014)The current study has two objectives: to validate the ability of the finite element (FE) software Atena to estimate the deformations of RC elements strengthened with fiber-reinforced polymer sheets and to assess the effect ... -

Betoninių konstrukcijų dispersinis armavimas: dabarties ir ateities iššūkiai
(Ketvirtoji jaunųjų mokslininkų konferencija "Fizinių ir technologijos mokslų tarpdalykiniai tyrimai" : pranešimų tezės : Vilnius, 2014 m. vasario 11 d. Vilnius, 2014: Technologijos mokslų sekcija : pranešimų tezės, 2014) -
Comparison of sandy soil shear strength parameters obtained by various construction direct shear apparatuses
(Archives of civil and mechanical engineering, 2014)An analysis of test results performed by common type of direct shear apparatuses shows that normal stress on the shear plane of soil sample is not equal to vertical component of distributed external load applied to the top ... -
Deformation analysis of RC ties externally strengthened with FRP sheets
(Mechanics of composite materials, 2014)The current study has two objectives: to validate the ability of the Atena finite-element software to estimate the deformations of reinforced concrete (RC) elements strengthened with fiber-reinforced polymer (FRP) sheets ... -
Deformation analysis of reinforced concrete ties: Representative geometry
(Structural concrete, 2017)Regardless of the simplicity of the test layout, interpretation of the tensile test results may be inadequate. Typically, a test of the reinforced concrete tie provides measurements of average deformations of the internal ... -
Distortions introduced by normalisation of values of criteria in multiple criteria methods of evaluation
(Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai, 2014)Quantitative multiple criteria decision aid (MCDA) methods of evaluation gain increasing popularity among researchers. The idea of the methods is to comprise values of criteria characterising each object into a single ... -
Effect of arrangement of tensile reinforcement on flexural stiffness and cracking
(Engineering structures, 2016)Due to the highly complex cracking behaviour of reinforced concrete structures, their design for serviceability is one of the most challenging tasks of engineering practice. Existing test data support a general inference ... -
Efficient technique for constitutive analysis of reinforced concrete flexural members
(Inverse problems in science and engineering, 2017)One of the most difficult issues in the theory of reinforced concrete (RC) is an adequate modelling of deformation behaviour, cracking and, particularly, post-cracking behaviour, as one of the major sources of non-linearity. ... -
Evaluation of level of heterogeneity of socio-economic development of a country
(The 4th World sustainability forum 2014 : conference proceedings papers : 1-30 November 2014. - (Sciforum Electronic Conference Series) : [Elektroninis išteklius], 2014)Heterogeneity of levels of socio-economic development of countries or country's different regions is undesirable. For the sake of sustainable development of a country or group of countries it is important to elicit relative ... -
Experimental and analytical investigation of deformations and stress distribution in steel bands of a two-span stress-ribbon pedestrian bridge
(Mathematical problems in engineering, 2017)The article is dedicated to the analysis of problems related to design of pedestrian bridges with flexible ribbon bands made of steel. The study is based on test results of a bridge model that has two spans (each with a ... -
Experimental and numerical (DEM and FEM) non-cohesive soil uniaxial compression
(Proceedings of the 23rd European Young Geotechnical Engineers Conference, EYGEC 2014, Barcelona, 2-5 September 2014, 2014)Compressibility of silica sand grains is investigated by tests and via numerical simulation, validation of obtained r esults performed. The Baltic Sea shore sand in Klaipėda region was used. Shape of sand grains was analyzed ... -
Experimental characterization of the properties of double-lap needled and hybrid joints of carbon/epoxy composites
(Materials, 2015)The effect of through-thickness reinforcement by thin 1 mm steel needles (z-pins) on the static tensile strength of double-lap joints of a carbon/epoxy composite was investigated. Two types of joints—z-pinned and hybrid ... -
Experimental identification of cracking parameters of concrete ties with different reinforcement and testing layouts.
(Procedia engineering. Modern building materials, structures and techniques, MBMST 2016, 2017)Despite a seeming simplicity of the direct tensile test layout, analysis of sources of scatter of the experimental results on cracking and deformations of reinforced concrete ties inspired the authors to investigate ...
