RESPONSE OF R.C. BARRIERS SUBJECTED TO TNT EXPLOSION BLAST LOADING

Reinforced concrete barriers have been commonly used in protecting theimportant building because the response of R.C. barriers subjected to blastloading is practically more acceptable than other materials used to build thebarriers. In this study, the response of R.C. barriers was detected due to theblast effects caused by two charge weights (50 kg and 400 kg); ANSYS 14was used to simulate the problem. A horizontal distance of 2 m between theexplosive TNT charge and the front face of wall was taken. The pressure onthe front face of the concrete barriers was measured at three levels. The R.C.barrier was entirely damaged when subjected to the blast effects caused by400 kg TNT explosion bomb. However, the 50 kg TNT charge had a minordamaging effect on the same R.C. barrier.
