Seismic response of steel plate shear walls considering soil-structure interaction

P. Memarzadeh, J. Mirlohi and F. Behnamfar

Abstract—Due to structural efficiency, Steel Plate Shear Wall
(SPSW) is widely employed in buildings as a principal system for
resisting lateral loads due to wind and earthquakes. An accurate
model of seismic demand for SPSW requires consideration the effect
of all components for analysis such as structural, foundation, subsoil
elements and the interaction between them. Such interaction may
alter the dynamic characteristics of structures and consequently may
be beneficial or detrimental to the performance of structures. This
investigation considers two typical SPSW designed according to
AISC requirements. The effects of soil-flexibility on seismic demands
of such frames resting on two soil types subjected to two different
earthquake ground motion is investigated using the time direct
method and a comparison is presented with the results obtained from
fixed-base. It is observed that soil–structure interaction affect the
seismic performance of SPSW and the effect of soil-flexibility must
be taken into account in dynamic analyses of SPSW.
