Different fibre percentages (0%, 0.5%, 1%, and 1.5% by weight of cement) are systematically incorporated into concrete mixtures. Compressive strength tests on cubes, flexural strength assessments on beams, and tensile strength evaluations on cylinders reveal insights into the material's load-bearing, bending, and stretching capacities. Human hair-reinforced concrete showed significant improvements in compressive strength. Results indicate a gradual strength increase in Human Hair Fibre Reinforced Concrete (HHFRC) up to an optimal percentage. At the same time, Aluminum Fibre Reinforced Concrete (AFRC) shows significant enhancement in higher fibre content. AFRC's superior mechanical properties stem from aluminum fibres high tensile strength and stiffness, enhancing bond formation and resulting in denser, stronger concrete. These findings inform the selection of fibre reinforcement for concrete structures tailored to specific project needs.","PeriodicalId":170482,"journal":{"name":"Journal of Construction and Building Materials Engineering","volume":"83 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141812763","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}

It is an effective design technique to improve efficiency in building construction. It was initially created in the 1960s at the Massachusetts Institute of Technology. By providing STS we can increase the strength and ductility of the building. It helps to cut down the number of interior columns and thereby reduce the cost of the building construction. This project involved using the ETAB software to undertake an analytical investigation into the seismic behaviour of a 16-storey steel staggered-truss system. The structural shape of the trusses was varied, and their influences on the seismic behaviours of the system were studied. The seismic performance of STS structures by varying the Vierendeel panel width was also evaluated. Time history analysis was used to analyse the models. From the analysis result maximum storey displacement, maximum storey drift and base shear are extracted. From the result, it was found that the model with warren trusses showed the highest strength and stiffness to the corresponding earthquake but all other truss shapes also achieved the target performance level and also the model with less Vierendeel panel width shows higher base shear and lower inter storey drift and displacement.","PeriodicalId":170482,"journal":{"name":"Journal of Construction and Building Materials Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132158865","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}

However, these concepts fail to account for the significant variability observed in buckling strength test results. This study aims to address this limitation by adopting a probabilistic approach to assess the buckling strength of steel columns; following the Indian standard specification IS 800-2007. In this investigation, the statistically variable nature of the material properties is considered by treating them as random variables and assuming a normal distribution. By incorporating this variability, a more comprehensive evaluation of the buckling strength can be achieved. The buckling strength of the steel column is computed using Merchant Rankine's formula, which takes into account deductive uncertainty. This formula considers various factors such as the slenderness ratio, live load to dead load ratio, and other relevant parameters to estimate the buckling strength of the column. Furthermore, the reliability of axially loaded columns is assessed using the First Order Second Moment (FOSM) technique. The effects of the slenderness ratio and the live load-to-dead load ratio on the reliability of the columns are specifically investigated and discussed. Overall, this study contributes to a more comprehensive understanding of the buckling strength of steel columns, incorporating statistical variability and providing insights into the reliability assessment of such structural elements.\"","PeriodicalId":170482,"journal":{"name":"Journal of Construction and Building Materials Engineering","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122703291","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}
