Ph.D. Thesis (Behaviour of Strip footing resting above void in Rock Mass)

Strip footing needs special attention when substantial underground voids of significant dimensions occur in natural rocks, since voids can compromise structural integrity. This paper uses a numerical simulation, based on finite element limit analysis with adaptive mesh refinement technique, to evaluate the effect of a circular void in the rock mass on the ultimate bearing capacity of a uniformly distributed loaded strip footing having a width, B, assuming that the rock mass obeys the Generalized Hoek-Brown failure criterion. Using parametric studies, the effect of several governing factors on the ultimate bearing capacity of the strip footing is investigated. The parametric consideration involves the void diameter, the vertical distance to the footing width, and the horizontal void’s distance to footing width from the axis of the footing, as well as the various rock parameters such as uniaxial compressive strength, unit weight, geological strength index, material constant, and disturbance factor. The effect of voids on the ultimate bearing capacity of footing is quantified and a reduction factor, , is proposed to set up the design charts from the numerical simulations. Moreover, the influence of the void’s presence on the development of potential failure planes below the footing is examined and discussed in detail. The results showed that the existence of a void beyond a depth of 3B, does not affect the footing's ultimate bearing capacity, and a void at a horizontal distance of 0.5B was found to be critical. Additionally, a multiple linear regression model has been developed to predict with good accuracy, as the proposed model’s coefficient of determination (R2) is noted to be 0.94.

Master of Technology (Study on the behavior of brick and RCC composite beams)

The main objective of this project is to study the replacement of concrete by bricks. In reinforced concrete beams, the strength of the concrete lying on the neutral axis (just above and below) is not fully utilized. So near the neutral axis as well as in the tension zone, concrete has been replaced by bricks in order to reduce the weight and cost of beams.  An experimental program is conducted on six simply supported concrete beams. All six beams are in two different groups, with every group having three beams. The first group of beams are reinforced concrete beams, and the second group of beams are composite beams. Both groups of beams compare with each other. The deflection readings are taken with the help of dial gauges. The dial gauges are at positions L/6, L/3, L/2, 2L/3, and 5L/6, where L is the length of the beams. The relationship between load and mid span deviation is being drawn.

Bachelor of Technology (Forecasting of traffic in Gorakhpur city, observations, problems and recommendations)

The project revolves around an in-depth analysis of the traffic scenario in Gorakhpur city, encompassing both current observations and future predictions, aiming to tackle existing traffic challenges and provide effective recommendations for mitigation. By delving into real-time traffic issues, the study identifies bottlenecks, congestion points, and areas of concern, leveraging comprehensive data collection and analysis techniques. The forecasting aspect of the project involves utilizing advanced modeling and simulation methods to anticipate future traffic patterns, considering factors such as urban growth, population dynamics, and infrastructure developments. By extrapolating these insights, the project aims to offer proactive measures to alleviate potential traffic problems before they escalate, promoting efficient mobility and reducing time waste. Obstacles encountered during the project may include data accuracy and availability, model calibration, and accounting for unforeseen variables. Addressing these challenges requires meticulous research methodology, validation techniques, and constant adaptation of the forecasting model. Recommendations will encompass a multi-pronged approach, incorporating infrastructure enhancements, intelligent traffic management systems, public transportation augmentation, and public awareness campaigns to encourage alternative modes of commuting. Ultimately, this project aspires to enhance the quality of life for Gorakhpur's residents by fostering a smoother, more sustainable, and resilient urban transportation network.
