The aim of this research is to produce high-strength Self-Compacting Concrete (SCC) by using industrial wastes such as GGBFS and fly ash as partial replacements for cement. Additionally, the research aims to investigate how the proportions of steel fibers should be selected to produce Steel Fiber Reinforced Self-Compacting Concrete (SFRSCC) mixes with the appropriate flow ability, passing capability, and segregation resistivity. To produce self-compacting concrete, GGBFS and fly ash are used as partial replacements for cement in proportions of 5%, 10%, 15%, 20%, 25%, and 30% by weight of cement. Furthermore, the impact of steel fibers on the characteristics of SCC is analyzed by utilizing steel fibers in different proportions ranging from 0.5%, 1.0%, 1.5%, and 2%. The research methods used to determine the concrete workability include the slump flow test and L-box test.
Non-linear static analysis serves as a suitable measure to evaluate the performance of a structural system. The careful selection of the load pattern is critical to arrive at an adequate performance evaluation. These force distributions do not represent the exact effects of varying dynamic characteristics during the inelastic response or the influence of higher modes. Hence, meticulous consideration must be given in choosing a certain load pattern. The present analysis seeks to evaluate and compare the response of an eight-story reinforced concrete structure by applying load patterns prescribed by several guidelines using Etabs 18.1.1. The results indicate with acute clarity that, in all cases, the shape of the lateral load distribution is what the response of the building is finely accustomed to. This is especially true when different patterns of load are considered and analyzed. The first mode is found to be predominant, and higher modes are negligible.
Irregular buildings are increasingly common in urban areas around the world, presenting unique challenges for seismic assessment and retrofitting. Pushover analysis and capacity curves have emerged as powerful tools for evaluating the seismic performance of buildings and developing retrofitting strategies. In this study, a methodology is proposed for seismic assessment and retrofitting of irregular buildings that incorporates pushover analysis and capacity curves. The methodology involves the use of finite element models to simulate the behavior of irregular buildings under seismic loading and the development of capacity curves to evaluate the structural response. The efficacy of the proposed methodology is demonstrated through a case study of an irregular building in a high-seismic area. Capacity curves developed using pushover analysis can identify potential failure modes in the building, and targeted retrofitting strategies can be developed based on these findings. Our results highlight the importance of using advanced analysis and design techniques to ensure the safety and resilience of irregular buildings in seismic areas. The proposed methodology can be applied to a wide range of irregular buildings and can contribute to the development of building codes and design guidelines for these structures.
India is the 3rd largest producer of steel with a capacity of 101 Metric Ton (MT), and this capacity is expected to grow up to 125-150 MT by 2025. The iron and steel industries generate millions of tons of various types of slag. These slags are generated during iron making and steel making processes, and are residue from these processes made of minerals like silica, alumina, and titanium from iron sand, as well as combinations of calcium and magnesium oxides. 2-4 tons of waste are generated for each ton of steel produced in different forms such as solids, liquids, and gas. The disposal of such slags is a major challenge for the steelmaking industry. With a growing availability of huge quantities of such slag materials, there is currently great focus on research to develop slag processing technologies that enable re-use of such slags in various infrastructure construction projects. The properties of the slags are very similar to the properties of natural aggregates in terms of both physical and chemical composition, and they have immense potential for extensive use in road construction and infrastructure projects as an alternative to natural aggregates. Rapid infrastructure development has led to a scarcity of natural aggregates as the demand is too high for them. These slags from the iron and steel industry are processed to make them suitable for use as natural aggregates replacements, contributing to sustainability in the construction industry. These slags can be used as an alternative to natural aggregates in sub-base, base and asphalt layers, and in concrete aggregates instead of being dumped as industrial waste near the plants. Standards, codal requirements, and suitable specifications need to be established for the large-scale use of slag continuously in construction, as well as for the implementation of large-scale recycling and re-use of slag from these industries, which can solve environmental issues in handling such industrial wastes.
Structural health monitoring is an essential tool for ensuring the durability and safety of structures, particularly in the face of changing loads and environmental conditions. With the increasing demand for real-time monitoring and control, the use of sensors and other diagnostic tools has become increasingly important. This paper presents a review of the current state of the field of real-time structural health monitoring, including the need for real-time monitoring, the types of sensors and diagnostic tools used, case studies and examples, data processing and analysis methods, challenges and limitations, and future trends and developments. The review highlights the importance of real-time monitoring in detecting damage early and preventing structural failure, improving safety, and reducing maintenance costs. The paper also identifies gaps in the existing research and provides recommendations for future studies. The results of this review demonstrate the potential of real-time structural health monitoring as an innovative approach to ensuring the durability and safety of structures.
