Performance of concrete linings under repeated dynamic loading
Scope of this research project is to provide an understanding on the seismic performance of unreinforced and lightly reinforced tunnel linings. Project duties: Provide an accurate simulation procedure (i.e. FE model combining the Concrete Damaged Plasticity constitutive model for the representation of concrete components with a kinematic hardening model for the simulation of the cyclic behaviour of soils); Validate Procedure against 1-g shaking experiments; Assess tunnel performance for different seismic records and describe failure mechanisms; Prepare charts that correlate induced damage state on tunnels, to known earthquake intensity parameters (PGA, Arias intensity, etc).
