The Effect of Soil Poissons Ratio on the Response of Buildings with Sufficient Embedment Depth

The present study highlights the effect of soil poissons ratio on the response of buildings with sufficient embedment depth. The interaction effect between the structure and its foundation control the dynamic behavior of the structure during seismic analysis. Not only the foundation of structure control the results of seismic analysis but also the embedment depth of the structure increase this effect. The ground motions produced by the seismic excitation at the base of the building are the result of shear deformation in the soil. The effect of the inertial resistance of soil surrounding the basement floors is taken into consideration by adding virtual masses to the basement floors to obtain more accurate shear forces acting on the flexible basement columns. The study calculates the response values at any required time and the maximum response values in addition to its time of occurrence.
