Abstract

Compared to bridges, underground structures are unjustly regarded as non-critical components of the road infrastructure in view of their supposed low seismic vulnerability. However experimental observations indicate that shallow buried rectangular structures, such as box culverts or rectangular tunnels, can be affected by shaking failure. In the literature there is no reliable model to calculate fragility curves of these types of structure. In this paper we suggest vulnerability models for shallow buried rectangular structures. In seismic zones underground facilities must be designed to carry static overburden loads and for the additional forces due to soil-structure interaction under seismic conditions. In the formulation proposed here we rely on simplified methods exposed in the literature. In conclusion the proposed method for evaluating the seismic vulnerability of shallow buried structures is applied to two case studies in the Autonomous Province of Trento (APT).
