On seismic response of stiff and flexible retaining structures

Abstract: A B S T R A C TThis paper presents an overview of the results of experimental and analytical studies of the seismic response of stiff and flexible retaining structures. These studies were motivated by very large dynamic forces in areas of high seismicity predicted by current seismic design methodologies based on the work of Okabe [3] and Mononobe and Matsuo [4]. However, there is no evidence of systematic failures of retaining structures in major earthquakes even when the ground accelerations clearly exceeded … Show more

“…The limitations of the pseudo-static method based on M-O were assessed by comparing the differences between pseudo-static and true dynamic behaviours in centrifuge tests by many researchers (Nakamura, 2006;Al Atik & Sitar, 2010;Brandenberg et al, 2015;Hushmand et al, 2016;Wagner & Sitar, 2016;Jo et al, 2014Jo et al, , 2017. In this regard, the definition of k h could be further improved in future studies.…”

“…For wall height H=7.5m, however, a slight increase of seismic thrust (50kN/g) is observed with increasing backfill acceleration. The above findings are in agreement with recent results of centrifuge testing (Sitar and Wagner, 2015;Wagner and Sitar, 2016;Candia et al, 2016;and Wagner et al, 2017).…”

“…Recent experimental studies have challenged the M-O method as being overly conservative for cantilever U-shaped walls [10] and free-standing retaining walls [11], and as providing a reasonable upper-bound for braced walls [12]. By contrast, analytical elasto-dynamic solutions [13], [14] and numerical modeling studies [15] have challenged M-O as being unconservative.…”
