SOIL–STRUCTURE INTERACTION IN STEEL BRACED STRUCTURES WITH FOUNDATION UPLIFT (2011)
In order to understand the structural behavior, it is useful to study the effects of soil-structure interaction. But usually soil-structure interaction studies are done with the assumption that foundation is fixed to the soil. During strong earthquake motions, uplift in some parts of the foundation may occur depending upon the type of soil which structure is located on. This paper investigates the nonlinear behavior of various steel braced structures placed on different types of soil with varying hardness. This can help in better understanding of the actual behavior of structure during an earthquake. Results showed that for structures allowed to foundation uplift, the softer the soil, the higher will be changes in seismic response.
