In recent decades, the awareness in civil engineering construction is rapidly increased. More advanced technologies are used to safeguard important civil engineering structures from terrorist attack. Now a days the threat level from terrorist attack is very high. To make an emphasis on safeguarding these structures, cold-formed steel stud wall can be considered as one among the blast resistant system. This paper presents the finite element analysis of structural system in extreme loading condition. In practice, a special effort has to be taken to conduct experimental investigation on steel studs subjected to blast loading and therefore finite element modelling(FEM) is considered. To validate the finite element modelling performed by authors, a reference work published by earlier researchers on cold-formed steel stud wall  is considered and examined in the present study. FEM is a tool which predicts the engineering physics of the real structure. Studs of different shapes and of varied thickness were modelled and analysed using ABAQUS. In the connection of stud wall system, buckle bridge acts as a connecting element to maintain stability. Different shapes of buckle bridge were used. In the present study, the influence of explosive mass is shown as a drastic damage level which was investigated using finite element analysis. To protect the skeleton of the stud wall, sheathing material was used. The material which absorbs more amount of energy and dissipate the energy plastically uniformly to the stud wall system is found out. Energy absorption and dissipation study were carried out in the current research. Two of the models act like a air bag in a car to delay the pressure timing inside the stud wall. Shape optimizations were carried out to increase the structural resistance against pressure. The models under consideration were capable of resisting the given blast load.
