122. Optimising the Performance of Bio-Mimetic Cellular Structures Under Blast Loads (I-12-GABD-016)

Nowadays, engineers are facing severe challenges from bomb attacks on buildings, which can cause catastrophic damage to internal and external structural frames and even collapse. For example, in 1995 the Oklahoma bombs had the charge weight of 1814kg TNT. The blast destroyed or damaged 324 buildings within a 4-block radius and 86 cars, killing 168 people and causing an estimated $652 million worth of damage. However, researchers have found that the cellular structure has shown sound bearing performance under extreme load and has huge potential for mitigating the effects of blast load. Thus, this project aims to explore and develop the potential for an enhanced cellular structure with superior energy absorption characteristics under blast loading by mimicking existing natural cellular structures.
