Extension of the fuel building (BK) at the site of Bugey

Check of the feasibility of the proposed design for the BK building extension, with seismic justification of the building and its extension at higher levels of earthquake than those chosen for the initial design.

Study of buildings collision

Study of buildings collision

Modeling of the seismic behavior of two adjacent buildings - Expertise of several collision scenarios (expansion joint filled or not filled)

Assess the harmfulness of the two buildings collision taking into account several hypotheses defining the expansion joint : empty, filled with concrete, filled with polystyrene (several elasticity modulus). Study of a strenghtening solution based on linking the two building with dampers.
