Lecture 22 Soil Structure Interaction Pdf Pdf Earthquake Soil structure interaction (ssi) analysis evaluates the collective response of three linked systems: the structure, the foundation, and the soil underlying and surrounding the foundation. problems associated with practical application of ssi for building structures are rooted in a poor understanding of fundamental ssi principles. 1. introduction first the very definition of the soil structure interaction (ssi) effects is discussed, because it is somewhat peculiar: every seismic structural response is caused by soil structure interaction forces, but only in certain situations they talk about soil structure interaction (ssi) effects. then a brief history of this research field is given covering the last 70 years. basic.
Fulltext01 Dynamic Soil Structure Interaction Analysis Pdf Waves Soil structure interaction (ssi) is a crucial concept in geotechnical and earthquake engineering that contemplates the interplay between structures and the ground they. Soil structure interaction (ssi) is a physical phenomenon in which the structure fails to behave independently and behaves in connection with the soil when an external load is applied to the structure as shown in the figure below(fig.2). in particular, the ground and the structures are greatly influenced by earthquakes, so this phenomenon is required as an essential consideration for seismic. Major effects of the interaction are flexibility arising from soil compliance and an energy feedback in the form of wave propagation into the soil during vibrations of the structure under investigation. it is especially important to consider interaction effects for massive, stiff, and lightly damped structures. Discounting effects of soil structure interaction, such as increased energy dissipation and period shift, has lead to more massive foundations than may be necessary. for both new design and retrofit of existing structures, accounting for soil structure interaction can significantly reduce construction efforts and cost.
