Fluid-Soil-Structure Interaction impacting the stability of the Pump Station Building
Keywords:
Excitation, Interaction, Frequency, Finite Element, DynamicAbstract
Within the first year after construction, there was excitation at a low-rise reinforced concrete building. It has been discovered that the structures perform up to 4 kPa of water transport activity while lying on a thick soil layer. To explore the dynamic behavior and interactions of the phenomena known as fluid-soil-structure interaction, three techniques have been used. Applying finite element computing, the dynamic of the soil-fluid and structure is represented, and the models of the actual and ideal-fixed base conditions are compared. According to research, the rigidity of the foundation and the volume of fluid moving through the pump station has a significant impact on the structure's modes frequencies. The vibration does occur and tends to enlarge over time, according to a time history string of displacements at an arbitrarily chosen position
