Mapping seismic exposure of building based surface peak ground acceleration: initial seismic risk assessment in Bandung Basin, West Java

Seismic Amplification of Peak Ground Acceleration, Velocity, and Displacement by Two-Dimensional Hills

There are valuable investigations on the amplification effects of the topography on the seismic response in the frequency domain; however, a question is that how one can estimate the amplification of time domain peak ground acceleration (PGA), peak ground velocity (PGV), and peak ground displacement (PGD) over the topographic structures. In this study, the numerical approach has been used for t...

Nonstationary Models of Seismic Ground Acceleration

A new nonstationary model is applied to represent seismic ground acceleration records. The model can be obtained by modulating both the amplitude and the frequency of a stationary process. It is not included in the class of oscillatory processes. Accelerograms recorded during the 1985 Michoacan earthquake in Mexico City are used to calibrate and evaluate the usefulness of the proposed and other...

seismic hazard zoning in iran and estimating peak ground acceleration in provincial capitals

growing environmental and social concerns, both on the part of decision makers and public opinion, have brought a new perspective to the perception of hazard assessments a valid alternative in the long-term, and an effective complement in short and medium terms, to traditional design procedure for a resistant and safe environment. results of the gradual development of research on the probabilis...

Seismic Risk Assessment of Power Substations

Power networks are among the most important infrastructures that without them, industrial, economic and social procedures will halt. Therefore, they should be planned for the most difficult conditions to provide services with minimum disruption. Power substations are of great importance to a power network, because any disruption in their components can produce extensive problems through the net...
