Prediction and Assessment of Lateral Displacement of Rock Mass Along the Length of the Horseshoe Cavern – A Numerical Modelling Approach
Abstract: The stability of the underground structures is a key to successful underground mining. Caverns are large underground openings constructed in rock mass for a variety of purposes. The properties of intact rock mass are generally overshadowed by the properties of discontinuities, if the discontinuities are present. Mechanisms of deformation and failure of underground openings in jointed rock mass are determined by the characteristics of the geometrical distribution of discontinuities. This …

Dynamic and Fatigue Analysis of Engine Crank Shaft by Using FEM Approach
Abstract: The internal combustion (ICE) engine crankshaft is a high-volume manufacturing component with a complicated shape. This converts the piston's reciprocating displacement into the crank's rotating motion. In this research, an effort is made to investigate how geometry modification might increase the fatigue life of a single-cylinder engine crankshaft. SOLIDWORK software was used to construct the modelling of the original and optimised crankshaft, which was then imported for analysis into ANSYS …

Rural Building Base Isolation for Seismic Protection Using LRB and Friction Isolator
Abstract: Over 50% of the population of India, which is still developing, lives in unreinforced masonry buildings. Masonry constructions perform poorly and can collapse suddenly because they are susceptible to seismic loads and loads acting out of plane. Building collapse not only destroys public property but also claims life. It has been demonstrated that base isolation approaches for these types of structures are advantageous; in the event of seismic forces, they …

Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …

Fracture and Failure of Recycled Aggregate Concrete (RAC) – A Review
Abstract: In the world, many countries put into effect the renewal plans and/or the laws and/or the regulations for recent engineering structures which have reached their lifetime, are risk prone and have been built lacking quality engineering, or without considering urban planning. Hence, many structures are demolished and this situation increases the amount of construction and demolition waste (C & DW). Also, resource consumptions are rapidly increased due to excessive constructional …

Effect of Bacillus Subtilis on Corrosion of Steel in Reinforced Cement Concrete
Abstract: Abstract Concrete is one of the most used building materials due to its cost- effectiveness, ease of availability, and versatility. It is the backbone of modern construction, being widely applied in infrastructure, residential, and commercial projects. However, it is particularly vulnerable to crack formation, which significantly reduces its service life. These cracks compromise structural integrity by allowing water ingress, which leads to the corrosion of reinforcing steel, eventually making the …
