Abstract: In urban areas where land is limited and buildings are closely spaced, deep excavations are necessary for the construction of surface and sub-surface facilities. Therefore, there is a concern that soil excavations resulting in a ditch or a trench adjacent to a building may adversely affect the response of nearby buildings when earthquakes occur. In this paper, the results of experimental study of building frame models in close proximity of excavations and subjected to artificial excitations are presented through a series of shake table tests. The study has been conducted to investigate the effects of the size and offset distances of excavations on the response of the building frame models founded on different types of foundation systems. It is observed that the width, depth and offset distance of the trench has a significant influence on the response of the building frame. It is seen that pile foundation with sufficient embedment depth produces less displacement at the top of the building as compared to other foundation systems.
