Reviewing on the Performance of Masonry, Reinforced Concrete and Underground Tunnels against Blast Loading

An explosion on the elevated structures caused by terrorist activities or manmade events can induce significant deformations in the Civil Engineering structures. Therefore, it is necessary to review the response of the structural systems such as masonry structures, reinforced concrete building structures and reinforced concrete tunnel. In order to understand the scope for protecting such a structures and the structural behaviour under blast loading, a detailed literature review is conducted. Based on the detailed literature survey, the investigations about behavior of masonry structures and reinforced concrete building structures were initiated since2000 however, the behavior of reinforced concrete underground tunnels was focused since the year 1990. Also, the literature reveals that the investigations on structural systems using analytical techniques limited in comparison to experiment and simulations. In addition to that, the response of the structural elements was predicted and the trend was calibrated and fitted logarithmically with the experimental results. Overall, the R 2 value was found between 0.99 to 0.88 against reinforced concrete building structures, masonry structures as well as underground tunnels.
