is there any example which is done by Brick8N_u_p_U elements?
I can find the command in OpenSees manual but why it's not in wiki? is it still working?
also the manual says: $alpha 1-Ks/Kt (ratio of void space =1 for soils, =0.6 for concrete...) in Brick8N_u_p_U
while in opensees wiki we have : alpha = h^2/(4*(Ks + (4/3)*Gs)) in SSPbrickUP Element
what is alpha in simple words?
thanks
