Seismic Behaviour Of Rcc Multi Storey Building With Retaining Wall

  Mohammed Mohiuddin Khan,  Shaik Mohammed Javid

The parking area is provided in the basement floors for most of the buildings. To retain the soil, the basement floor has a retaining wall around the periphery of the building.The outside periphery of the building is supported on the retaining wall and columns. Horizontal soil pressure acts on the retaining wall of the building structure. On the outer periphery of the lateral earth pressure building structure, attempts are being made to study the effect of seismic forces on a building with retaining wall.For three distinct story height models, seismic analysis is performed. In addition to interaction with soil structure using linear time history analysis in ETABS, the models are equipped with single basement floor and double basement floor as well as lateral earth pressure acting on the retaining wall. Together they're all 12 models. The structure response is explored in terms of base shear, roof displacement and maximum story drift.The models interacting with lateral earth pressure and soil structure the percentage increase in base shear is 30-42 percent and 30-48 percent in X and Y direction for single story basement. The base shear is risen 15-30 percent for the double story cellar and 60 percent for the soil structure interaction along X and Y axis. Models with lateral stress acting on retaining wall together with earthquake force the highest roof displacement is observed in Model 3 with 42% and 48% along X and Y direction for single basement floor when considering groundwater interaction. And the model 3 is improved 60 percent for double basement ground when considering soil structure interaction.
