Seismic Design Situation

Combination for Seismic Design Situation (EN 1990)

E_{d} = \sum_{j \geq 1} G_{k, j} " + " P " + " A_{Ed} " + " \sum_{i \geq 1} ψ_{2, i} \cdot Q_{k, i}

G_k,j	Characteristic value of the permanent action j
P	Governing representative value of prestress
A_Ed	Design value of a seismic load
Q_k,i	Characteristic value of a non-governing variable action i (a secondary action)
'+'	"is to be combined"
∑	"common effect of"
