Abstract:During earlier days, not much importance was given to the blast resistance design of doors in blast resistant design of structures. Later on, due to large numbers of deaths because of failure of doors, high priority was given to the blast resistant design of doors. In earlier cases, doors were traditionally designed using huge solid materials to resist the blast load. The use of traditional design results in increased material quantity and cost of construction. Recent technological advancement lead to use of engineered materials wherein use of reserved material strength was made to resist blast loading. The blast load is the load with high energy and higher frequency, thus need special attention for analysis and design of structural components. The present study deals with the different doors configurations wherein effect of stiffness, natural frequency and mass of the door is investigated. Finite Element (FE) analysis is carried out to study the dynamic response of door under a given blast loading using ABAQUS®. In the present investigation, tempered AISI 1045 steel is used as door material. Modal analysis is carried out to obtain modal frequency of different door configurations considered in the present investigation wherein mass of all the doors are kept almost constant. Herein, blast loading from 5 kg TNT at a standoff distance of 1 m is applied to the door to understand their dynamic response. The peak displacement of door at different locations has been computed to understand their failure pattern. From the results, it is observed that displacement is significantly reduced just by changing the geometry of door with other parameters being same.
