The increase of tunnel excavations in urban areas calls for improved methods to assess the risk of damage on existing buildings.

Abstract
The increase of tunnel excavations in urban areas calls for improved methods to assess the risk of damage on existing buildings. Laboratory tests performed in a controlled environment provide a better insight of the parameters governing the structural response and can be used as validation of computational models. This paper presents an experiment carried out on a 1/10th scaled masonry fac¸ade subject to tunnel induced settlement. The results demonstrate the determinant effects of soil structure interaction, presence of openings and brittle masonry cracking on the final damage, with crack width up to 6.3 mm for a maximum applied settlement of 10 mm.| File | Dimensione del file | Formato | |
