Non dissipative seismic retroffitting of a frame structure using shear walls

Evaluation of the technical and economical feasibility of two different design approaches for seismic retrofitting of RC frame structure: - Conventional Approach: Design of a new ductile structural core serving as a stair shaft -Non-conventional Approach: Use of an external structural coating system designed assuming a non-dissipative behavior The work is subdivided in two main parts. In the first one, a series of information contained in the literature, both historical and technical, has been collected to provide for the necessary background both for seismic analysis and retrofitting design in order to define the two retrofitting strategies. In the second part the design of the RC walls is presented in detail and finally confronted, from a technical and economical point of view.
