Seismic Soil-Structure Interaction Response of Tall Buildings
Significant improvement has been made with the advent of numerical tools and methods in the predicting capabilities of behavior and building performance when an earthquake strikes. Current building designs tend to produce safer structures, being resiliency the most important consideration to minimize indirect losses due to strong earthquakes. This resiliency is quantified in terms of recovery time; the time necessary to achieve a safe operational level for a structure after an earthquake. Performance based earthquake engineering is a probabilistic assessment of building risk and damage frequently used to quantify earthquake-induced losses of structural and non-structural elements. The main goal of this paper is to estimate the intensity measures and engineering demand parameters for a hypothetical tall building located in an urban environment, downtown Los Angeles, including the influence of foundation soils in the building response. Numerical simulations of a hypothetical tall building supported in a mat foundation are performed using the pressure-dependent multi-yield surface constitutive soil model coded in OpenSees. The building is subjected to three earthquakes levels. Based on the building responses and computed peak story horizontal accelerations, maximum inter-story drifts, and settlements, conclusions are drawn about the influence of soil-structure interaction in the response of tall buildings.
