Soil liquefaction vulnerability assessment of Sylhet city based on SPT value
Abstract: Bangladesh is an earthquake-prone country due to its geographic location. Sylhet, a divisional city, is situated in Zone IV, the most seismically active area in the country, according to the Bangladesh National Building Code (BNBC). A major earthquake can cause devastating effects in the subsurface, such as liquefaction, landslides resulting from a reduction of soil shear resistance. In this study, liquefaction potentiality of soil in Ward No. 9 of Sylhet …

Analysis of Retrofitting Concrete Structure Using FRP Laminates
Abstract: Retrofitting is referred to as modifying existing equipment or structure with additional or new components or members. To make older structures more resistant to accidents or seismic activity, retrofitting is referred to as modifying existing equipment or structures with new or additional members or components. An existing structure is less susceptible to damage when it is retrofitted. The use of retrofitting is on the rise right now. The structures' strength, …

A Review Study of Offshore Structure
Abstract: Seaward development is the establishment of structures and offices in a marine situation, as a rule for the generation and transmission of power, oil, gas and different assets. Earthquake design of offshore platforms in seismic active areas is one of the most important parts in offshore platforms design. Dynamic response of piles in offshore platforms is a function of the Characteristics of the loading, dynamic pile-soil interaction behaviour and dynamic …

A Review on Mining Induced Earthquake
Abstract: Seismicity in mines, in general, depends on depth, production rate, mining geometry and geological discontinuities such as dykes, faults etc. Induced earthquakes differ from normal earthquakes in that they have occurred prematurely due to an external trigger. Except for much of the micro seismicity, the virgin state of stress in the Earth’s crust depends on, among other factors, gravity and tectonics. In, or near, a mine the stress state is …

Variation of Ground Acceleration with Increase in Lateral Distance
Abstract: Ground acceleration induced by dynamic loading decreases with increasing lateral distance from the source because of wave attenuation and energy dissipation through the ground. Accurate estimation of ground acceleration at different distances is essential for evaluating the safety and performance of nearby structures, particularly in blasting, seismic, and heavy construction activities. This study presents a simplified linear attenuation model for estimating ground acceleration at greater lateral distances using limited measured …

Geological and Geophysical Studies of the Ninety East Ridge: A Brief Review
Abstract: The Indian Ocean serves as a unique laboratory for studying the impact of both global and regional stressors on environmental changes over various geological epochs. Its distinct hydrological conditions and geographical location make it an ideal focal point for research into these phenomena. Of particular interest within the Indian Ocean is the Ninety East Ridge (NER), which holds significance as the world's longest linear rise. Researchers have long hypothesized that …

Characterization of Bamboo-Fiber Reinforced Geopolymer Composites
Abstract: In this project, we plan to produce and assess a new, eco-friendly composite made from geopolymer (from a combination of fly ash and GGBFS), strengthened with chemically treated bamboo fibres for retrofitting earthquake-resistant buildings. Geopolymer is produced by activating a mixture of fly ash and GGBFS with sodium silicate and sodium hydroxide solutions. We have produced and analyzed bamboo fibre-reinforced geopolymer composites as potential materials for seismic retrofitting of structures …

Fractal Analysis of Vertical Component of VLF Electric Field Related to Major Shallow Earthquakes (5.5 < M ≤ 5.9, depth ˂ 10 km) occurred in Indian Ocean and China
Abstract: Recording of amplitude of vertical component of VLF electric field is continued at Chaumuhan, Mathura (27.5° N, 77.68° E) at the frequency f = 3.012 kHz from 24 March 2011 with the help of vertical antenna. In this paper, fractal analysis of VLF data is carried out for the April 2012 and July 2013 months and the fractal dimension is computed using Higuchi’s method to study the influence of three …

Analysis of RC Frames Using Different Bracing Systems in Different Positions and Zones
Abstract: Structures are mainly built to enhance the performance of several activities like recreation, transportation, power generation, etc. They are built to sustain the loads coming on them during their service life by carrying adequate strength and also limit the deformation by possessing enough stiffness. Strength of a structure depends mainly upon the characteristics of material with which it is constructed. Stiffness is dependent upon the cross-sectional and geometrical properties of …
