Seismic retrofitting of under-designed structures is a consolidated approach to risk management. Several options are available for the achievement of the vulnerability reduction goals, each of those having peculiar performances in respect of different technical and non-structural criteria. Selection of the best solution is a non-trivial task, because criteria may conflict each other. MultiCrite...

Peak ground acceleration is the maximum shaking intensity parameter in geophysics. To prevent big loss of infrastructure, dam site or multistorey buildings as well power project due to any seismic hazard, it essential mitigate damages. Seismic hazard analysis for peak was carried out hydropower Gilgit Baltistan effect hazard. Seismicity and tectonic map drawn distribution events.Study region di...

This paper discusses the suitability of two optimization methods for use in seismic retrofit location selection. The structure for analysis is modelled after a seven story RC structure in California, USA, built according to 1964 Los Angeles City Building Code. The OpenSees parallel computing software package is used to model the dynamic behaviour of a test structure. Past earthquake records are...

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...

The Earth is being monitored every day by all kinds of sensors. This leads an overflow of data in all branches of science nowadays, especially in Earth Sciences. Data storage and data processing are the problems to be solved by current technologies, as well as by those accessing and analyzing these large data sources. Once solutions have been created for collecting, storing and accessing data, ...

West Africa is considered a region of low seismicity. However, the monitoring earthquake activity by local seismic arrays began very early (as as 1914) in but catalogs are incomplete. In 1991, Bertil studied seismicity based on networks stations Ivory Coast and neighboring countries. The reference work Ambraseys Adams well recent earthquakes given international data centres were also used for c...

Fragility curves represent the probabilities that structural damages, under various levels of seismic excitation, will exceed the specified damage states by means of earthquake intensity damage relations. Conceptual aspects related to seismic vulnerability, damage and risk evaluation are discussed first, together with a short review of the most widely used possibilities for the seismic evaluati...
