Paper Details

The recent rise of terrorist attacks has reinforced the need for mitigation of damage caused by blast loadingon unreinforced masonry walls. The failure of masonry walls has been widely witnessed even in low magnitude blasts.The failure of masonry often leads to flyingdebris resulting in loss of life and disabilities/injury to many people. Theprimary goal of the techniques is to prevent the loss of life while simultaneously preserving the integrity of the structure.This paper presents theparametric study of blast loads on confined masonry dry-stacked masonry walls by usingnumerical techniques. It seeks to present the state of the art analytical hydrocodes such as ANSYS-AUTODYN. Theresults have been obtained for the charge weight parameter of the explosivewith the blast analysis. Some parametricstudies of field interestwere also carried out for understanding the behaviour of masonry walls against blast loadsandderiving some useful conclusions. The numerical simulation technique can provide a theoretical referencefor thedesign of walls and may help in reducing the requirement of extensive testing. The most significant parameter forassessing the severity of damage in structures under blast loads is the scaleddistance. It has been demonstrated that theuse of confined dry-stacked masonry walls offers great potential walls to resist low or moderate blast loads and containflying debris.
