The necessity of constructing the structural systems known to be important against earthquakes such as multi-storey structures, dams, viaducts, suspension bridges, nuclear power plants requires the understanding of the mutual dynamic interaction between the superstructure and the ground. The aim of this course is to develop the calculation models that take into account the structure-soil interaction in earthquake analysis of engineering structures and to teach solution approaches.

1.Vibrations of rigid foundations.

Investigation of circular, rectangular and strip type foundations

1.1. Investigation of dynamic behavior of superficial and buried foundations in elastic semi-infinite environment and obtaining of impedance functions (dynamic stiffness-flexibility terms) by analytical and numerical solution methods

1.2. Investigation of dynamic behavior of superficial and buried foundations in layered soils and obtaining of impedance functions (dynamic stiffness-flexibility terms) by analytical and numerical solution methods

2. Structure-soil dynamic interaction problems

2.1.Direct solution methods (finite element and boundary element model)

2.2. Soil subsystem method (examination of single and multi degree of freedom systems based on rigid foundations, modeling of soil subsystem with numerical and simplified solution approaches)
