Analytical influence of soil-structure-interaction on structural performance by using ETABS
Abstract: Soil conditions have a great deal to do with damage to structures during earthquakes. Hence the study on the energy transfer mechanism from soils to buildings during earthquakes is critical for the seismic design of multi-story buildings and for upgrading existing structures. Thus, the need for research into soil–structure interaction (SSI) problems is greater than ever. Moreover, recent studies show that the effects of SSI may be detrimental to the …

Performance of Structure with Fixed Base and Lead Rubber Bearing: Review
Abstract: Base Isolation approach is the most normally used method to defend a shape from earthquake. The thinking in the back of this approach is to detach the superstructure from floor with the aid of introducing bendy isolators between basis and superstructure. These isolators soak up electricity or vibrations and shield shape from an earthquake. Since the last fifteen years, the base isolation technique has been regarded as one of the …

Fourier Transform and Optical Analogy of the Sharply Pulsed E.P. Seismic Signals Propagating Through The Core of Earth
Abstract: AbstractLike light rays that encounter a water surface, seismic rays are governed by the laws of reflection and refraction. Eventually, there exist wave properties within these. Due to rigorous BIS (breakdown of integrated system) processes, severe consequences like earthquakes occur. The waves that are generated in an earthquake down into the interior of the earth are called earthquake waves or seismic waves. In the present paper, the author will consider …

Response Spectrum Analysis of RC Buildings Constructed on Plain and Sloping Ground with Different Configuration of Shear Walls
Abstract: Abstract Buildings constructed on slopes are different from those in plains. They may be irregular and unsymmetrical in horizontal and vertical planes, and torsionally coupled. Hence, they are susceptible to severe damage when affected by earthquake ground motion. We can’t avoid the future earthquakes but the preparedness and safe building construction practices for earthquakes can certainly reduces the extent of damage and loss of both property and life. Shear wall …

STRUCTURAL BEHAVIOR OF FLEXIBLE AND SEMI-RIGID BEAM-COLUMN JOINT CONNECTIONS BY FEM
Abstract: This study investigates the structural behavior of flexible and semi-rigid beam-column joint connections in cold-formed steel (CFS) structures, focusing on the use of Finite Element Modeling (FEM) to simulate their performance under various loading conditions. Traditional analysis methods often oversimplify beam-column connections, treating them as either perfectly rigid or fully flexible, which does not accurately capture real-world joint behavior. In reality, many beam-column joints exhibit semi-rigid characteristics, where the stiffness …

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 …
