Abstract: A novel technique to enhance the seismic behaviour of existing RC framed structures is proposed. The technique is based on the introduction of friction devices in the vicinity of the expected plastic hinges in the original structure. The proposed technique is applied to an existing RC soft storey building. Static and dynamic time-history nonlinear analyses are conducted on a simplified model. The efficiency of the proposed upgrading technique is evaluated in terms of strength, stiffness and energy dissipation.…
