However, conventional educational programs in construction engineering and management are often inflexible, providing limited opportunities for students to actively participate in experiential learning that could contribute to firsthand experience and guide them in finding solutions. This study addresses this gap by developing and empirically evaluating an innovative gamified pedagogical approach aimed at teaching linear scheduling through guided active exploration within a digital gaming environment. The proposed approach and its associated game are grounded in constructivist learning theory. A scenario-based interactive game named Zebel was created using the Unity game engine. Employing a set of pre-and post-assessment tools, the proposed method was implemented and assessed in a graduate-level course on construction planning and scheduling to gather empirical data. The results indicate that the proposed pedagogy effectively guided students, even those without prior knowledge of linear scheduling, in discovering fundamental concepts and systematic solutions for the presented problems.","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"238 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140275729","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}

A widely used material in most civil works is PVC, which is used in pipes and accessories for the project's hydro sanitary system. When the work is finished, a lot of PVC waste is discarded and is not recycled. In this research, the physical-mechanical properties of concrete are evaluated, using a dosage where the coarse aggregate is replaced by recycled and crushed PVC, in percentages ranging from 3% to 9%, mainly analyzing its behavior against compression and flexion at the age of 28 days, and obtaining its elastic modulus. The results obtained allow us to determine if the PVC added to the concrete mix gives us favorable results (greater compression and bending strength) or unfavorable results (higher costs, concrete slump, etc.)","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"82 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140277231","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}

PtD aims to eliminate construction hazards during the design phase to prevent or reduce occupational injuries, illnesses, and fatalities during the construction phase. PtD is achieved by incorporating prevention considerations into all designs that may impact workers' safety. Civil and architectural engineers are considered the primary initiators of PtD in the construction industry, with the ability to educate project owners and construction practitioners about its benefits and importance. However, this group has a few, if any, educational interventions or training opportunities to develop PtD knowledge and skills in the United States. As a result, faculty members who may be willing to teach the PtD concept in their design courses (e.g., concrete, steel, foundation and traffic design courses) have limited exposure to the PtD concept and no clear guidelines to integrate PtD into their courses. This study surveys engineering department chairs in the United States to assess their perceptions about integrating PtD into the engineering curriculum. The findings showed that most participants do not favor incorporating PtD as a standalone course in the engineering curriculum. However, they expressed their support for integrating the concept as small modules within existing engineering design courses. Faculty members, teaching engineering design, should be provided the necessary resources to achieve this. This study contributes to our understanding of PtD integration strategies within engineering programs.","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"237 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140274412","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}

Corruption has a substantial negative impact on the quality and effectiveness of construction projects. In an effort to address this issue, the authors conducted a comprehensive literature review to identify effective strategies for reducing corruption in the construction industry. Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) framework, the researchers meticulously assessed 19 relevant peer-reviewed articles. The review yielded a set of six key measures that can be employed to mitigate corruption within construction workplaces. These measures encompass regulatory, administrative, compliance, promotional, investigative, and disciplinary strategies. Accordingly, the study provides a thorough explanation of these identified measures, offering valuable insights for construction practitioners and policymakers alike in their battle against corruption.

The objectives included calculating the simultaneity coefficient and determining the maximum probable flow for each student's residence. To achieve these objectives, active learning methodologies, specifically project-based learning (PBL), were adeptly employed to enrich students' practical knowledge and foster collaboration. The process began with architectural surveys of residential properties, followed by inventories of pipes, sanitary appliances, and wet rooms. Measurements of flow rates at various faucet openings (25%, 50%, 75%, and 100%) were conducted, along with the recording of operating pressures within home networks. This data served as the foundation for creating calibration curves, a process carried out over 120 days. Using the collected data, each student developed a hydraulic model of their network and compared the software results to practical measurements. The participants calculated the simultaneity coefficient (Ks) and maximum possible flow for their dwellings using hydraulic design concepts and regulatory standards. The results were documented in technical reports, a video tutorial, and infographics. The research highlights the importance of understanding residential water usage patterns and their potential for optimizing water delivery systems. It also underscores the value of experiential learning, which helps students bridge theory and practice, enhancing technical skills and their understanding of hydraulic engineering.","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"311 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140281368","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}

Several companies are now producing recycled plastic for use as construction material in single-story houses. One commercially available layout involves assembling Recycled Plastic Lumber units in a running bond pattern, forming panels confined by horizontal and vertical tie elements joined through bolted steel plate connections. As production of houses is industrialized, the architectural layouts are standardized according to specific distribution and dimensions. This paper presents the findings of an experimental program aimed to characterize the seismic behavior and properties of a one-story house model. To facilitate practical application, the model is referred here as Architectural Standard Model (ASM). The objectives of the test campaign were to investigate the structural behavior of the constituting members and assemblies, and the response of structural walls to cyclic static lateral loads. Three natural scale wall specimens were tested in-plane and two out of plane. Results of natural scale cyclic loading tests demonstrated that structural system of the ASM can perform acceptably safely under high seismic loads if it is adequately fixed to the foundation. The results showed that out of plane loading was the critical pattern and behaved like a unidirectional plate that transmitted load to the columns. In plane observed behavior exhibited predominating rocking component, which suggests considering an evaluation of the system's response using dynamic methods.","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"576 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140282968","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 Netherlands, the shear capacity of reinforced concrete slab bridges is found to be insufficient. In particular, the shear and punching shear capacity of reinforced concrete slab bridges subjected to concentrated loads from the design tandem or truck is subject to discussion, as the shear behavior is situated in between one-way and two-way shear. Currently, an experimental program is being conducted at Delft University of Technology to determine the shear capacity of straight and skewed reinforced concrete slabs under point loads near to the support. This paper presents the results of the 25 tests conducted on six straight slabs of 5m × 2.5 m × 0.3 m subjected to a proof load testing loading protocol. The failure load and modes of the slabs are described in detail. Reinforced concrete slabs under concentrated loads can fail in shear, punching, and flexure, as well as a combination of these failure modes. The results of the experiments are compared to strength predictions obtained by using current design models and current methods for assessment. These experiments demonstrated that the Dutch guidelines, which are based on previous slab experiments, are an improvement as compared to the Eurocode for the assessment of existing reinforced concrete slab bridges. Ultimately, this work provides recommendations for bridge engineers tasked to assess reinforced concrete skewed slab bridges.","PeriodicalId":477265,"journal":{"name":"Proceedings of International Structural Engineering and Construction","volume":"27 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140269048","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}
