Seismic 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 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...
متن کاملExternal seismic pre-isolation retrofit design
This technical note outlines the design of an external seismic pre-isolation system proposed for use in LIGO Livingston. The goal is to reduce the effects of the site’s excess ground noise in the 1 3 Hz frequency band, allowing detector noise performance equivalent to that of the 4 km LIGO Hanford detector. The center histogram in Figure 8 shows the most troubling aspect of the excess noise qui...
متن کاملGeotechnical Aspects of Light Structures on Expansive Soils
The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures. Since swell potential and swell pressure are key properties of expansive soils, the swell parameter...
متن کاملDissipative Bracing-Based Seismic Retrofit of R/C School Buildings
A dissipative bracing system incorporating pressurized fluid viscous spring-dampers has been studied for many years by the authors as an alternative seismic protection strategy for new and existing frame structures. As a concluding stage of this activity, a set of demonstrative case studies was examined to illustrate the enhancement of seismic performance and the economic advantages guaranteed ...
