Abstract

Widespread damage within urban centres (e.g. in the 2011 Christchurch Earthquake) has highlighted the need to better understand the seismic structure-soil-structure interaction (SSSI) between closely-spaced adjacent building structures. In this paper, such interaction will firstly be investigated for one single and two identical adjacent model building structures on non-liquefiable soil, using a combination of dynamic centrifuge modelling and non-linear elasto-plastic Finite Element (FE) modelling. After validating the FE approach against the centrifuge test data, it is subsequently used within a Monte-Carlo approach to simulate response under a range of 20 different input motions of differing spectral characteristics, at a range of shaking strengths. This will demonstrate the sensitivity of the observed SSSI behaviour to the input motion characteristics. Finally, this set of results will be interpreted in a probabilistic sense to demonstrate how the effects of SSSI may be incorporated within a Performance-Based Earthquake Engineering framework.
