When transitioning local laboratory practices into distributed environments, the interdependent relationship between experimental procedure and the technologies used to execute experiments becomes highly visible and a focal point for system requirements. We present an analysis of ways in which this reciprocal relationship is reconfiguring laboratory practices in earthquake engineering as a new ...

in this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. the objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...

The development of design seismic forces is reviewed. The earthquake engineering was shown to have developed in the last 60 years. The characteristics of ground motion and structural response were gradually understood over the last five decades. The damage statistics from recent major earthquakes indicated that the severe damage was observed in taller buildings. The ratios of buildings with ope...

NEES (the George E. Brown, Jr. Network for Earthquake Engineering Simulation) is a national, networked resource for next-generation experimental earthquake engineering research and education in the United States. The goal of NEES is to support open access to and use of NEES’s facilities and data by the earthquake engineering community. The system infrastructure to support the NEES activities is...

⎯ Hazard mitigation and structural dynamics have been important additions to the undergraduate civil engineering curriculum. UCIST (University Consortium on Instructional Shake Tables) has worked toward improving educational opportunities in this area for nearly 10 years. For the past 8 years, the US National Science Foundation has sponsored a cyberenvironment project referred to as the Network...

Broader Impacts. The Southern California Earthquake Center (SCEC) conducts a broad program of earthquake system science that seeks to develop a predictive understanding of earthquake processes with a practical mission aimed at providing society with improved understanding of seismic hazards. In partnership with earthquake engineers, SCEC researchers are developing the ability to conduct end-to-...

The earthquake engineering community recognizes the need to improve current seismic codes and design methods in the light of recent inadequate behavior of building structures. Presently, the performance-based earthquake engineering is being envisioned as the solution to this problem. In this new design approach, the desired behavior of the building is formulated first in the conceptual stage fo...
