For these reasons, the industrial revolution 4.0 is a movement involving large-scale changes and a transversal implementation of technology in industries' value chains. In the same way, the basic principles of Industry 4.0 can be applied to the construction sector in the term Construction 4.0, a movement that seeks to integrate new technologies with the processes of the industry, generating added value that allows for increased productivity, and close gaps with other industries. Therefore, a bibliometric analysis focused on Cluster analysis is presented, which allows knowing the research state of Construction 4.0 and its implications in developing the Construction sector. The search equation in the Web of Science (WOS) database was queried by topic (Construction 4.0), from which 225 scientific articles related to the subject were obtained. These articles are directly related to this new movement from new materials, more efficient construction processes, BIM, Digital Twin (DT), Artificial Intelligence (AI), and other topics of research relevance in Construction 4.0. The main results show low research participation of Latin America in implementing technologies and methodologies offered by Construction 4.0. In contrast, developed countries, such as the United Kingdom, China, the United States, and Australia, show a greater interest in research and adopting these trends.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139225547","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}

As a result of the large accumulation and shortage of disposal yards, handling BA has become an immediate challenge. This paper presents studies on the Atterberg limit, shrinkage index, linear shrinkage after 7 days of curing, compaction, and unconfined compressive strength (UCS) tests (following 7 days of curing) of BA and lime-BA assorted expansive soil (ES) by differing BA content from 0 to 18% at an interval of 3% and adding 4% lime by dry weight of ES. The outcomes disclosed that the inclusion of BA and lime beneficially controls the shrinkage attribute. According to the research, changes in moisture-density correlations resulted in reduced maximum dry densities (MDD) and greater optimal moisture content (OMC). The volume change characteristic of ES can be mitigated by mixing BA and lime. In addition, test findings showed that both BA and lime-BA enhanced axial stress while reducing axial strain. As a result, a substance that was once thought to be a misery to the environment and society has become a benefit to the civil engineering industry.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"274 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139244583","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}

In the international literature, studies have found that changes are the leading cause of productivity losses in construction projects; however, limited studies have been done in Chile in this regard. This context is understood as an opportunity to learn from the existing literature about the impact of changes in construction productivity, more importantly, such learning can contribute to the discussion of productivity improvement in the Chilean construction sector. This study recommends that more studies are necessary to be done in Chile regarding the impact of changes in construction projects. Namely, future studies should be based on an extensive database of projects so that generalization can be drawn for the construction industry. Additionally, the data collection process of changes in construction should be improved, paying specific attention to the size of changes, the timing of changes, and the scale of assessment—namely activity, project, and industry levels. Ultimately, this study aims to contribute to the discussion about productivity improvement in Chilean construction as this remains one of the main challenges in the industry","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130843149","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}

In addition, the demand is determined according to the NEC-15 load combinations, using the live, dead and earthquake load states; for the verification of the axial capacity of columns, the effect of the earthquake is used, considering the over-resistance. After that, a design by capacity is carried out in the structure without reinforcement, based on the capacity of the beams, and in the case of reinforcement, an analysis is carried out based on the capacity of the diagonals. It is observed that both the original structure and the reinforcement do not comply with the earthquake resistant philosophy, and it is likely that an earthquake will be affected in a future.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114595592","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}

Traditionally, the use of BIM has been evaluated by maturity models; however, it does not provide an integral evaluation of BIM use. BIM Use Assessment (BUA) was proposed as a tool to satisfy this need, it is based on the evaluation of several states that compose necessary characteristics to perform each BIM use successfully. BUA was applied to measure projects that have BIM advanced use in Colombia, Chile, and Spain. However, there is none an integral evaluation in the early stages of BIM use. Therefore, the objective of this research was to evaluate the incipient BIM use. Accordingly, 23 private Ecuadorian projects, were evaluated using BUA. As expected, the analyzed projects have lower levels than the other projects evaluated by BUA. The high percentage of projects were at the levels that require the appropriate use of 3D models, and the collaboration issues were common deficiencies. This research results could be used in the development of strategies to reduce mistakes; thus, leading to an agile BIM implementation.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121568988","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}

In recent years, an alternative to the steel fibers has emerged in the market for concrete reinforcement: the macro-polymeric fiber. However, there is few research on its performance as a reinforcement element in concrete, particularly when it is a high strength concrete. Given this, the behavior of high strength concrete, without fiber and with macro-polymeric fiber, both in fresh and hardened state, is analyzed in this paper. The workability was evaluated by the slump test and the mechanical properties were evaluated by the tests of compressive strength, Barcelona, flexure of prisms and punching of plates. It was found that, depending on the property to be analyzed, the increase of the macro-polymeric fiber content may be unfeasible. In the flexural test in prisms, for example, most parameters evaluated showed no significant changes when increasing the fiber content. In addition, it was observed that the same concrete mixture may present different behavior depending on the test performed.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128100031","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}

Load-deflection curves, modes of failure and the pattern of the cracks are studied. Also, the influence of compression strength of concrete, the configuration of CFRP (U shape and 2 side bond shape) and shear span to depth ratio (a/h ratio). The results show that the shear capacity of RC beams strengthened by CFRP increased by a maximum percentage of up to 111.7% compared to the unstrengthened beam. Also, it is found that by increasing the compressive strength of concrete from 40 MPa to 65 MPa the load-carrying capacity increases by 28% and the stiffness also increased, while the decrease of shear span to depth ratio from 1.66 to 2.33 leads to increasing the shear capacity by 23%. The maximum load of beam strengthened with U shape increased by up to11.5% when compared with the same beam strengthened with two side bond shapes of CFRP. However, the gain in the strength was reached to 22.7% for beams strengthened with CFRP laminate compare to unstrengthened beams. The strengthening of RC beams by CFRP laminates using the near surface mounted (NSM) technique is more efficient than the externally bonded reinforcement (EBR) technique for all beams in the shear behavior. The finite element models provide a good level of accuracy compared to experimental results and ACI-440.","PeriodicalId":369360,"journal":{"name":"Revista Ingeniería de Construcción","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130458556","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}
