A numerical probabilistic approach for pounding effects on the seismic response of adjacent RC structures in dual systems strenghened by tension-ties
Abstract
Dual systems of reinforced concrete (RC) moment frames with concrete shear walls have been used as common lateral load resisting systems in earthquake prone countries. In order to overcome damages caused by seismic actions in the above systems, a strengthening by cable-like members (tension-only tie-elements) can be used. In the present study, a numerical probabilistic treatment for the pounding problem concerning the seismic interaction between adjacent structures strengthened by cable-ties in such dual RC systems is presented when the input parameters are uncertain. This problem concerns the elastoplastic-fracturing unilateral contact between neighbouring structures during earthquakes and is considered as an inequality problem of dynamic structural contact mechanics. The Monte Carlo method is used for treating the uncertainty concerning input parameters. The purpose here is to estimate numerically and to control actively the influence of the cable-ties on the seismic response of the ...adjacent structures. Finally, in a practical case of two structures in a dual system, the effectiveness of the proposed methodology is shown.
