Influence of wall friction on Active Earth Pressure in Model Test
Abstract: Earth pressure theories occupy a paramount position in the field of geotechnical engineering. The knowledge of active earth pressure under static condition is essential in designing a retaining wall as the damage to such retaining structures may lead to disastrous failure. A retaining wall helps in maintaining the ground surface at different elevations on either side of it. Without such a structure, the soil at higher elevation would tend to …

Analysis of Elevated Liquid Storage Tank on Sloping Ground with Variable Heights
Abstract: Past earthquake events have shown that even well-designed elevated water tanks can suffer severe damage or collapse. Much of this damage occurs due to a limited understanding of the behavior and appropriate selection of supporting systems during the design process. With a large mass concentrated at the top of slender supports, these tanks are especially vulnerable to horizontal seismic forces. Therefore, it is crucial to evaluate the strength and performance …

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, …

Review and Design of Voltage Sag Compensation Using Improved DVR System with Proportional Integral Controller
Abstract: The aim of this investigation is to remunerate voltage inthree-stage power systems during voltage sag conditions induced bybalanced and unsymmetrical deficiencies in power distributionsystems or offices in plants. Voltage plunges (also known as "voltagesags") are abrupt drops in voltage size. Their definition is usuallyanywhere between a couple of power-system recurrence trends and acouple of moments. The popularity of voltage plunges stemsprimarily from their effect on end-client hardware. Mechanicalprocesses can fail …

Performance of Offshore Steel Jacket Platforms under Near-source Ground Motion Type Pulses
Abstract: Behaviour of jacket type offshore structures under ordinary ground excitations has already been addressed by a number of researchers. However, their performance under near-source ground excitations has not been particularly addressed in the literature. Records from recent earthquakes, such as the Kobe Japan (1995) and Chi-Chi Taiwan (1999), have revealed that the dynamic excitations in near-source are dominated by a large, narrow band and long period pulse caused by rupture …
