Study of Performance based Antiterrorism Design for Bridges

Abstract:

Basic thought and contents of performance based antiterrorism design for bridges are discussed,including the relationship between the antiterrorism fortification level and antiterrorism performance of bridges,the determination of antiterrorism performance grades for bridges and the objective of antiterrorism performance.The concept of the multi layered defense is proposed.This paper presents a general framework of bridges’ antiterrorism design comprising three design phases and six design processes.
