Making explosives is an easy and ever-available process. Especially for terrorist groups, as well as increased terrorist attacks that have taken place in the country, there is a need for an explosion phenomenon. The load imposed by the explosion is applied to all building levels, but the largest share belongs to the levels of the explosion.
Due to the fact that the explosion load is a lateral load, then the lateral load systems (bending frame, shear wall and braid) play a fundamental role. Due to the fact that the speed variations in heavy structures are less than light ones, steel structures are faster due to the lightness and wear of the members. One of the most prominent instruction in the field of explosion phenomenon and its effects on the structure is UFC3-340-02. By studying this recipe, it was observed that for the design of the frame and the process of analysis and design is not specified. UFC3-340-02 has been developed analysis and design for single-member column and beam and By connecting these single members, it forms the frame. Since the frame also affects the distribution of power between its members, a two-dimensional steel frame with a number of openings 3, 5 and 7, and two types of elevations 3 and 7 as the frame of research, and with the help of UFC3-340-02 Upload completed and Results were extracted from nonlinear dynamic analysis using SAP2000 software and the results of the frame analysis were compared with the results presented by UFC3-340-02.
