Abstract

Soil-structure interaction contemplates a series of comprehensive studies, such as those related to the use of springs to represent the soil-structure behavior in complex structures. In this context, the present paper aims to apply methodologies available in the technical literature regarding the inclusion of the combined effects of soil, foundation, and structure to represent a timber-concrete composite pedestrian bridge of the Polytechnic School of the University of Sao Paulo. Numerical models associated with soil-structure interaction methodologies were developed and calibrated using experimental data from monitoring campaigns on the footbridge. Vertical displacement and natural frequency results displayed good adherence with experimental data. Overall, the use of soil-structure interaction provided a satisfactory improvement in the numeric responses. This paper thus demonstrated the importance of adopting adequate representation for the foundation and soil elements to represent the actual behavior of an asset, displaying the influence of the soil-structure interaction. The modeling configuration of this work enables the selection of more reliable numerical models for future analyses. (AU)
