blast loading on cylindrical shell
i know how to calculate blast load profile on a concrete cylindrical shell supported along the edges, also how to calculate load at various points and time of arrival of blast load .
please tell me how to apply transient load on the structure.
for e.g,
load at node 1=33kn/m*m , time of arrival ta=13ms
load at node 2=38kn/m2 , ta=15.5ms
load at node 3=42kn/m2 , ta=19ms.
