Behavior of Basalt-FRP Reinforced Self-Compacting Concrete (SCC) Deck Slabs in a Real Bridge Considering Arching Action

Fiber Reinforced Polymer (FRP) material is advocated for use in bridge structures to solve the corrosion and degradation problem of conventional steel reinforcements, thereby improving its durability and service life. Also, compared with ordinary concrete, self-compacting concrete (SCC) mixed with abundant industrial waste materials is expected to achieve sustainable development of concrete infrastructure. However, the research examining the performance of FRP reinforced SCC slabs in a real bridge is rather limited. This paper describes the application of basalt-FRP (BFRP) in a real bridge deck slab cast with low energy SCC. Since few studies have considered arching action on a real bridge deck slab, this paper aims at extending previous laboratory research using glass-FRP (GFRP) and BFRP reinforcement in in-plane restrained slabs to real bridge deck slabs. This study primarily investigates the serviceability behavior of real bridge deck slabs and utilizes the arching theory to predict their ultimate bearing capacity. The bearing capacities of real bridge deck slabs have been compared with the current specification requirements and the predictions considering arching theory. The test results indicate that a significantly low percentage of FRP reinforcement is possible in real bridge deck slabs due to the advantageous arching action.

Tribal Tourism

Tribal tourism is an important junction of cultural discovery and sustainable development, providing unique insights into indigenous cultures' ways of life while creating economic possibilities and protecting cultural legacy. This literature-based research offers an anthropological look into tribal tourism in India, analyzing its implications for cultural preservation, sustainable development, and community empowerment. This research analyzes major themes and trends in tribal tourism after conducting a thorough examination of academic literature, government papers, and industry publications. It investigates the complex interactions between visitors and indigenous people, emphasizing the significance of cultural sensitivity, equitable partnerships, and community participation in tourism development programs. Furthermore, the study investigates the function of ethnographic research methodologies in understanding the sociocultural dynamics of tribal tourist destinations, highlighting the need of respectful collaboration and ethical issues. Furthermore, this study examines the influence of tribal tourism on sustainable development, namely its ability to produce cash, offer job opportunities, and encourage environmental conservation practices among indigenous communities. It also tackles issues including cultural commercialization, loss of authenticity, and the importance of responsible tourist practices in mitigating negative effects and ensuring the long-term viability of tribal tourism operations. Finally, this literature-based study adds to our understanding of the complex relationship between tribal tourism, culture, and sustainable development, providing insights for policymakers, researchers, and practitioners looking to promote responsible and inclusive tourism practices that benefit both indigenous communities and visitors.
