along the bridge's 18.3 m (60′) length. The charge weights and locations
were assigned based on their probability distributions and were randomly
generated to several scenarios (Mahoney 2007).
The static equivalent loads of each attack scenario can be calculated.
Table 15.10 displays these calculations for attack scenario 1 as an exam-
ple. Having the distance between the blast and each bridge joint ( D ) and
the angle of blast (θ i ) calculated, the program AT-Blast (ARA 2004) based
