Study of Interaction on Earthquake Response of Adjacent Buildings Founded at Different Depths

The aim of this paper is to study the interaction between adjacent buildings with different foundation levels under earthquake loading conditions. Buildings and soil are represented by two different models. In the first case the building itself is modeled with standard frame element, whereas the soil behavior is stimulated by a special grid model. In the second case, the building and soil are represented by plane stress or plane strain elements. The modulus of elasticity of the ground is varied. Just like the modi-fication of the modulus of elasticity the varying relations of inertia have a strong influence on the section forces within the build-ings. The analysis is carried out using numerical program which has been developed based on the axisymmetric fein element method in corporation of grob element for soil region and wave input technique transit boundary condition. Interaction of the pro-posed method is demonstrated in numerical examples
