BREEAM (Building Research Establishment Environmental Assessment Method) is the world’s most widespread real estate impact assessment method and certification standard. In BREEAM certification the evaluation of health and quality of life in buildings, construction materials, innovation, economic and social responsibility, energy, water management, ecology, and pollution must be done. For collection of the precise data the Building Information Modelling (BIM) was used as a tool. BIM is increasingly used in the world not only for design but also for the entire life cycle management of the building. The BIM application ensures efficient use of resources and smoother construction management. This article explores the application of BIM technologies in BREEAM certification, identifying potential benefits and limitations.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84295101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different author’s experimental studies of the thin-walled built-up cross-sections of various lengths and shapes have been reviewed. The cross-section of the thin-walled built-up columns is assembled by connecting two or more profiles at their webs or flanges. The cross-section can be assembled indirectly – by using intermediate plates. The connections of the profiles and plates can be self-drilling screws, bolts, rivets or welds. The step of the thin-walled profile connections has an impact to the load bearing resistance of the cross-section. The increase to the load bearing capacity of the cross-section can be up to 16% when profiles without stiffeners are connected with a smaller connection step. The effect to the load bearing resistance of the decrease of the connection step length of the thin-walled cross-sections made of profiles with stiffeners was insignificant and sometimes unfavourable. Different cross-sections were analysed, and their effectiveness was compared. The more effective were cross-sections with a higher cross-section height and width, assembled of profiles with web and flange stiffeners. The ratio of the strength of the axial compression to the cross-section area of the built-up columns can be up to 80% higher when built-up cross-section is assembled using profiles with stiffeners, compared to the built-up cross-sections assembled using profiles without stiffeners.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89592589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the ways to differentiate people’s needs and satisfy them in real time is to use a digital twin (DT). The digitalization of the construction process uses building information modeling (BIM) methodology. When BIM is applied from the very beginning of the idea of implementing an object of the built environment, information about the object begins to be accumulated from the very beginning of the object’s life cycle. Accumulating information about the object is particularly important to extract the best version of the DT model. It is also important to understand that it is not enough to have a real object and digital information about it. The digital twin will work if information links between the real and virtual environment are provided.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85328155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The negative effect of reinforcement prestressing on the bearing capacity of the dapped-end is analyzed. The numerical beam model is made based on an experiment and a nonlinear analysis is performed using the DIANA FEA software package to determine the effect of different intensity of reinforcement prestressing on the bearing capacity of the dapped-end beam. The results are compared with analytical calculations and the behavior described in the literature. The prestressing of the reinforcement is shown to reduce the bearing capacity of the dapped-end when tensioned reinforcement is not extended to the end of the beam above the notch. The load capacity of the numerical model is reduced by 9.67% and reduced by 25% based on analytical calculations. When designing dapped-end beams, it is necessary to assess the effect of reinforcement prestressing on the bearing capacity and cracking.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80977384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, one of the most critical sectors of the economy is the financial sector. The bankruptcy of a company in the financial industry affects both individuals, businesses, and organizations, negatively impacting the economy. Therefore, it is essential to anticipate the likelihood of bankruptcy of companies in the financial sector and make management decisions to avoid the risk of bankruptcy. There are many methodologies for analyzing and predicting corporate bankruptcy that differ in content, number, and accuracy of measurable indicators, so it is crucial to identify which model is most appropriate for assessing the risk of corporate bankruptcy in a particular sector. Given that the financial sector plays a crucial role in economic development and that the consequences of their bankruptcy are harrowing, the aim is to identify the most sensitive model to the risk of bankruptcy in this sector. To achieve this goal, we reveal the concept of bankruptcy, present the internal and external causes of bankruptcy, and systematize the results of bankruptcy risk research of companies in the financial sector. Bankruptcy probability assessment models are also presented and compared, and their applicability to the financial industry is discussed. An analysis of the literature revealed that the most commonly used models for assessing the bankruptcy risk of companies in the financial sector are the Altman Z Index, the Ohlson O Index, and the Zmijewski X Index. After applying these models in the case of three banks (SEB bank, UAB Medicinos bank, and General Financing bank) using 2021. The Altman Z model found that the most sensitive bankruptcy predictor was the probability of bankruptcy.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84289898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These emergencies create the need for an airline to have an emergency plan in place to ensure business continuity. Drawing on specific literature, the factors influencing the assessment of airline business continuity decisions are examined in the context of COVID-19. The study seeks to find out what the airlines’ intentions were when making strategic decisions. The study analyses the decisions taken by the airlines in order to achieve business continuity, using a systematic approach, combined with a case study approach, and systematises the factors influencing the evaluation of the decisions. The use of a multi-criteria evaluation approach allowed the solutions to be ranked according to their evaluation results.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87154603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shortage of electronic components was first noticed in car factories, and then in the entire electronics industry. The US, Taiwan and China are the largest markets for semiconductor manufacturers, which are no longer able to meet the everincreasing demand for chips. Lack of production capacity is mostly felt by consumers of final products. Ensuring a steady supply of chips is an important task for major manufacturers. In order to ensure the supply of chips, it is important to establish criteria by which semiconductor manufacturing countries can be arranged. The ranking will help identify the countries that are worth investing the most in the short term. The European Union, the United States and major telecommunications companies will invest billions of dollars in 2022 to replenish the market. The article analyzes the criteria for investing in chipproducing countries. The main focus of this analysis is the chip supply chain. Each of the analyzed countries has at least one stage of chip production: design, manufacturing or assembly. Data analyzed: gross domestic product, net exports, price of one dollar in relation to the national currency, monthly average wages, Oxford COVID-19 government response severity index and semiconductor export volume. These criteria allow us to rank countries from the most attractive to the least attractive for investment. The TOPSIS method was chosen for ranking, but comparative data analysis and analysis of scientific literature and other sources of information were also applied. Method principle, formulas and application – to be described. It was determined which country is the most favorable for short-term investments, taking into account the given criteria.","PeriodicalId":30324,"journal":{"name":"Mokslas Lietuvos Ateitis","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76999690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
