Blast resistancec steel structure design Example:Part 3

This course  part 3 objective is toknow how to design a steel structure under blast load by illustrated a complete example to apply  the blast resistance analysis and design for steel structure. Part 1 was focusing about  the blast load phenomena and the materials properties values under blast load. This part3  is presenting also the methods of analyzing the structure under blast load and part2 is the application on example  of blast resistance for the concrete structure.

In this part 3 presents the case study illustrates the application of blast analysis by using the graph method, the closed formula and also the single degree of freedom (SDOF) by the integration method will be applied. The Newark integration method is illustrated theoretically  in part1 and in this part3 presents this method and apply it in example through an excel sheet. These methods for applying structure analysis will be applied for the roof deck, roof purine, wall panel, wall girt and the frame structure and the bracing structure system as usual.

The multi degree of freedom (MDOF) method is also applied for the steel frame by using nonlinear analysis. The foundation design check for blast load will be discuss by checking the overturning, sliding and also design the foundation based on the maximum dynamic load.
