Abstract

Blast load is a dynamic , impulse load and difficult to predict. It not only cause damage to the structure but also takes the life of the people.Cladding material is a light weight material, mobile, versatile, economical material used for energy abortion of the structure exposed to blast load. Here a study is made on ten story structure exposed to blast load. Each floor as a three degree of freedom that is one along translation between floor and the structure and two translation between structure and cladding material, totally thirty degree of freedom is considered. The cladding material is used for the connection of every floor. Rubber material is also used for the connection between the cladding and structure. The responses in terms of pressure impulse curve, story drift , story drift ratio is also considered.The maximum energy is observed by using cladding material of the structure and considerable amount of responses is reduced.
