A Comparative Analysis of Decision Making Methods for the Seismic Retrofit of Rc Buildings
Several different technical options are nowadays available to seismically upgrade an existing building. Selecting the best one with reference to a given structure generally represents a complex problem. In fact many and generally conflicting are also the points of view by which each alternative has to be judged. Decision support systems like the so called Multi Criteria Decision Making (MCDM) m...
متن کاملSeismic Retrofit for Electric Power Systems
This paper develops a two-stage stochastic program and solution procedure to optimize the selection of seismic retrofit strategies to increase the resilience of electric power systems to earthquake hazards. The model explicitly considers the range of earthquake events that are possible and, for each, an approximation to the distribution of damage that is experienced. This is important because e...
متن کاملEnergy-Based Design Criterion of Dissipative Bracing Systems for the Seismic Retrofit of Frame Structures
Direct sizing criteria represent useful tools in the design of dissipative bracing systems for the advanced seismic protection of existing frame structures, especially when incorporated dampers feature a markedly non-linear behaviour. An energy-based procedure is proposed herein to this aim, focusing attention on systems including fluid viscous devices. The procedure starts by assuming prefixed...
متن کاملReliability-based Design of Seismic Retrofit for Bridges
This research focused on developing reliability-based seismic retrofit assessment procedures for highway bridge columns. Fragility curves were developed to assess the relative performance of various retrofit methods considering several limit states. Analytical fragility curves are developed from scaled earthquake records and structural response models. A simplified, single-degree-of-freedom (SD...
متن کاملUsing Composites in Seismic Retrofit Applications
This report was prepared to provide a comprehensive review of the state-of-the-art for using composite materials for seismic retrofit applications. The emphasis is on seismic retrofit of reinforced concrete columns. The report is presented in eleven chapters. Chapters 1–3 provide a basic introduction to composite materials, including discussions on the types of matrix and reinforcement material...
