Probabilistic methods for seismic upgrading by ties old RC buildings considering input parameters uncertainty
Abstract
The probabilistic seismic response of existing old reinforced concrete (RC) structures is numerically investigated. These RC structures have been damaged due to extreme environment actions and are to be seismically upgraded by using cable elements (tension-ties). Special attention is given to uncertainty for the input parameters of the structural elements. For this purpose, use is made of Monte Carlo methods. A double discretization, in space by the Finite Element Method and in time by a direct incremental approach, is applied. The unilateral behaviour of the cable elements, which can undertake tension stresses only, is strictly taken into account and results to inequality constitutive conditions. Finally, using damage indices, the probabilistic optimal strengthening version of cable-systems is chosen for the case of multi-storey RC frames under earthquakes sequences.
