Identification of an Efficient Method for Practicing Designers to Incorporate Soil-Structure Interaction Effects

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.
