Item Numerical Simulations for Seismic Response of Laterally Loaded Pile Foundation(Springer Science and Business Media Deutschland GmbH, 2024) Barik, T.; Chaudhary, B.Pile foundations are frequently used to safely transfer enormous loads from superstructures to deeper soil layers in order to support structural weight. Due to earthquakes, piles are subjected to dynamic loadings, which causes significant damage to the foundation as well as the superstructure. Laterally loaded piles vulnerable to earthquakes have a complex dynamic reaction. Earthquake motions shake the foundation ground which can make it unstable. Due to this unpredictable behaviour, the research has been carried out for the last few decades on it but still the behaviour is not understood completely. Therefore, an attempt has been made in this study to investigate the dynamic response of the pile foundation due to earthquakes by performing numerical study using Finite Element (FE) program, PLAXIS 3D. In addition to it, several parameters have been studied to understand the effects of several parameters like soil properties, earthquake features (acceleration, frequency etc.) on pile behaviour, considering soil-pile interaction. It can be stated that this numerical simulation will be useful for the researchers and practicing engineers working on this domain. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.Item Influence of basalt fiber on the behavior of beam - column joint under cyclic loading(Elsevier Ltd, 2023) Dineshkumar, G.; Palanisamy, T.Beam-column joints are immensely complicated areas of reinforced concrete constructions. The strengthening of such components can have a significant impact on the earthquake resistant constructions because the rapid collapse of a building could occur if these beam-column joints fail. Recently, designing of reinforced concrete beam-column joints to resist earthquake load becomes more important using ductile design and high strength material. The fibers addition in a concrete directs to an improvement in cracking resistant, ductility, deformation and energy absorption capacity. However, there are currently many distinct types of fibres with various materials and geometric features are used in fiber reinforced concrete to improve the above said properties. The use of basalt fibre, an alternative material made from natural sources that comes from volcanic rock, is the main topic of this essay. The beam-column junction was used to assess the structural behaviour parameters for basalt fibre reinforced concrete, including load–deflection behaviour, ductility, stiffness value, energy absorption capacity, and energy index. From this work, it shows that the natural based basalt fiber shows excellent structural behavior when compared to control concrete. Basalt Fiber Reinforced Concrete (BFRC) has the potential for widespread application in the construction of concrete structures as well as in earthquake-prone regions. © 2023
