EARTHQUAKE HAZARD MITIGATION STRATEGIES AND COUNTERMEASURES OF HIGHWAY INFRASTRUCTURE
This paper is to briefly introduce the efforts in the US in earthquake hazard mitigation of Highway Infrastructure,including bridges,through a thorough and comprehensive seismic research program.This program initiated in the 1991s Transportation Equity Acts (TEA) and has been working through three TEAs and funded more than $36 Millions in research tasks.The program focuses on three fundamental issues,which includes:(1) A State-of-the-Arts Specifications in Seismic Design for all new highway constructions,(2) A State-of-the-Practices Manuals in Seismic Retrofitting for all existing highway coustructious,and (3) A Systematic Risk Analysis Program to estimate the earthquake loss of the roadway system using network system approach.The most important factor to reduce or mitigate the earthquake loss of the highway infrastructure is through a well preparedness,including those above three items.
