Dynamic Soil Structure Interaction of a High-Rise Building Resting over a Finned Pile Mat

open access: yesInfrastructures, 2022
High-rise building safety is generally supported by pile-mat systems. They must be sturdy enough to withstand potential lateral loads brought on by earthquakes, wind, dredging, and machine vibrations, in addition to increased axial loads.

Time History Analysis of Various Shapes of Building Frame

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: The seismic performance of different building frames varies greatly according to shape. (I.e. geometric plans of the structure). By using the original earthquake forces, i.e. the various time history earthquakes, the realistic behaviour of buildings can be examined.
