Abstract:
The soil-structure interaction (SSI) influences the many aspect of structure i.e.
cost, safety and serviceability. Therefore, it plays an important role in substantial
development of any country where the devastating earthquakes have occurred repeatedly. SSI techniques have been come out as powerful methods to incorporate
multiple degrees of freedom. Building structures can accommodate more degree of
freedom due to the support flexibility, and therefore different dynamic characteristics than the rigidly mounted structures. But, the concerns of practitioners are
paved in hectic efforts to incorporate SSI. Practicing engineers are facing many
challenges to implement SSI practice due to difficult literature and time consumption. Therefore, the overall aim of this research program is to incorporate SSI
practice in analysis and design of building structures. The goal of this study is to
investigate through literature research; the performances based assessment of SSI
effects and identify an efficient method for practicing designers to incorporate SSI
in analysis and design of structures. In this regard, the documentation of development regarding SSI, preferably, in last five years was carried out to come up with
an efficient approach which designers can easily adopt in their practice. It is concluded that N2-SSI is an efficient and easy to adopt SSI method in which the soil
effect is introduced on the non-linear response of structure. This work will increase
the awareness of SSI effects and convince practicing designers to incorporate SSI
in their analysis and design of structures.
