Hi everyone.
I am currently handling a structure that requires dynamic analysis for blast loads. I hope someone could enlighten me on the following:
1. Why is there a need for a dynamic analysis on blast loading? Is applying max blast wave pressure in Staad not enough? What's the advantage of doing dynamic analysis on blast against static?
2. I read that you have to define time history when analyzing for blast. How will you define that one considering there will be different impacts of blast on front wall, rear, sides and roof?
If you can communicate with me directly, that would be very helpful. Giving me example of blast analysis would be extremely beneficial.
I am not always here in this community because I am very busy in the office.

In STAAD.Pro, you can specify the Blast Loading as in Impulse Time History Loading and find the response of the structure accordingly.
Please find the attachments. Please let me know if you need any further information on this.
hi, why is it necessary to use the self weight command in the same load case where we are defining the time history load? if I want to ignore the effect of self weight and compare a static point load with dynamic load of same intensity but time varying, i do not want to use self weight in time history load case. is that possible?

above video shows no use of self weight, may be it is internally considered.
it also shows some damping effect, is it possible to see it similarly in staad?
Thank you
