Determination of Additional Springs According to Effective Soil Method by Kolar and Nemec

Additional spring determination on outer edges/nodes of foundation according to the effective soil method by Kolar and Nemec

s=s0[4, 5]~s04.5
c2,v=c2,xz=c2,yz=c1,z⋅s2
k=c1,z⋅c2,v  
K=c2,xz + c2,yz4=c2,v2

k

Line spring

K

Single spring

s0

Range of subsidence basin (settlement around 1% of that at the foundation edge)

c2,v

Shear capacity (here, equal in x and y) [reference values from 0.1 c1,z for loose sand to 1.0 c1,z for solid rock]
