Modelling tunnelling-induced damage in framed structures with masonry infill walls




Modelling tunnelling-induced damage in framed structures with masonry infill walls


Masonry infill walls contribute to the stiffness and weight of framed structures, and they may influence soil-structure interaction mechanisms induced by nearby tunnel construction. To understand this interaction and its potential influence on building damage, coupled numerical analyses are conducted in this study. These analyses simultaneously consider the tunnel excavation and the soil-structure interaction. Previously neglected aspects are addressed, such as damage initiation in the infill walls (by considering an elasto-plastic formulation for the masonry), possible infill wall separation from the frame, and embedded strip and raft foundation schemes. Numerical modelling results are evaluated in terms of displacements, distortion parameters, strains and associated damage categories to quantify the influence of these aspects on the structural response.
