Abstract

<p> Many above-ground water reservoirs constructed more than 50 years ago are deteriorated and always threatened for seismic risk. There are not any conventional method to assess the seismic safety of above-ground water reservoirs. Proposed method includes a new performance-based seismic assessment based on Level 2 reliability formulation which is appropriate with world standard rules requested from WTO. A numerical sample is given how to assess the seismic safety of the reservoir which is modeled to be one-degree-of-freedom vibration system to be simplified from the symmetry of a 3D model.</p>
