Abstract

The numerical assessment of the building’s dynamic response due to railway traffic usually requires advanced numerical models. However, from an engineering perspective, simple and efficient methodologies are desirable. Thus, a hybrid approach is formulated, combining numerical/experimental results and post-processing techniques. The underlying concept of the methodology is the so-called SSI (soil-structure interaction) curves, which, when applied to the input motion experimentally evaluated in free-field conditions, can replace the kinematic effects induced by the presence of the building, avoiding their consideration in the simulation of wave propagation on the ground. A numerical application example is presented, clearly showing the potential of the proposed methodology in assessing the building’s dynamic response to railway traffic in the vicinity.
