Evaluated of Annular Baffle on Dynamic behavior of Elevated Liquid Storage Tanks under Blast Loading

In last decades with an increase in the number of terrorist attacks and other unintentional explosions, the study of blast loading and response of infrastructures have gained much importance. Elevated liquid storage tanks are one of the major infrastructures that play important role in industries. L...

description	In last decades with an increase in the number of terrorist attacks and other unintentional explosions, the study of blast loading and response of infrastructures have gained much importance. Elevated liquid storage tanks are one of the major infrastructures that play important role in industries.

Hence, understanding the dynamic behavior of liquid storage structures under blast loading through numerical simulations is of utmost importance.
