EN 1998-5 Seismic Effects

If the coefficients kh and kv are not obtained from measurements it is necessary, providing the analysis is carried out according to 1998-5 Eurocode 8: Design of structures for earthquake resistance - Part 5: Foundations, retaining structures and geotechnical aspects, to input these coefficients as follows:

where:

α

-

ratio of the design ground acceleration on type A ground (ag / g)

S

-

soil factor defined in EN 1998-1:2004, chapter 3.2.2.2

R

-

factor for the calculation of the horizontal seismic coefficient - see tab.

for:

for other cases:

Type of sheeting structure

R

Free gravity walls that can accept a displacement up to dr = 300αS (mm)

2

Free gravity walls that can accept a displacement up to dr = 200αS (mm)

1.5

Flexural reinforced concrete walls, anchored or braced walls, reinforced concrete walls founded on vertical piles, restrained basement walls and bridge abutments
