Current practice enables the design and assessment of structures in earthquake prone areas by performing time history analysis with the use of appropriately selected strong ground motions. This study presents a Matlab-based software environment, which is integrated with a finite element analysis package, and aims to improve the efficiency of earthquake ground motion selection by accounting for ...

This document provides an assessment of the current state of advanced airborne and spaceborne remote sensing and ground-based technologies applicable to the analysis of seismic risk and vulnerability of buildings and lifeline systems. Continuous Global Positioning System (GPS) ground deformation monitoring and seismological networks provide critical measurements for understanding the earthquake...

In this paper, it was firstly confirmed by FEM analysis of ground during earthquake that two kinds of techniques using both displacements of hollow and natural grounds in seismic deformation method were equivalent. Then, the authors were proposed a criterion for evaluating applicability of seismic deformation method, based on comparison of calculated results of both the above-mentioned techniqu...

■ Abstract Real-time seismology refers to a practice in which seismic data are collected and analyzed quickly after a significant seismic event, so that the results can be effectively used for postearthquake emergency response and early warning. As the technology of seismic instrumentation, telemetry, computers, and data storage facility advances, the real-time seismology for rapid postearthqua...

Batubesi Dam which is located in Sorowako region in the middle part of Sulawesi island had been designed with seismic coefficient about 0.20g. The region constitutes an active earthquake zone with the recurrence frequency and magnitude of the earthquake are relatively high. The region is located on and active fault zone due to lateral fault movement (strike-slip) of Matano fault, Palukoro fault...

The ground motion at Yucca Mountain, Nevada, was evaluated, and its effect on siting and conceptual design of a prospective nuclear waste repository was considered. Two levels of ground motion are proposed in this report for seismic design, the higher level for design of facilities classified as important for off-site radiological safety, the lower level for on-site safety. It is recommended th...

a study on the evaluating equivalent damping and response modification factors of frames equipped by pall friction dampers is presented. to do so, buildings with various stories were considered. nonlinear and linear dynamic time history analysis has been performed to evaluate equivalent damping for pall friction dampers. ground motions with various frequency characteristics scaled with iranian ...
