Equivalent static load method parameters

[Mohamed_Mahmoud_Mobd3]

Hi everyone,
I'm trying to make my way through Robot and i have a problem in defining Equivalent static load as seismic load according to the European code but i found that i can't enter the value of the parameters "B,S,Tb,Tc, etc...". i can only choose the soil class. Why?

Hi @Mohamed_Mahmoud_Mobd3 

That's because you are using the Bs 1998 code not the general one. the first one allows you to choose the soil type and spectrum type and direction and the values of S . Tb , Tc , Td is already stored at it and it's automatically used but if you wanted to enter them manually you'll have to use the general as in picture, that will allow you to enter every single parameter value.
