The effect of earthquake frequency content on the seismic behavior of concrete rectangular liquid tanks using the finite element method incorporating soil–structure interaction

Seismic response factors of reinforced concrete pedestal in elevated water tanks

“…Such studies date back to as early as 1940s and later by works of Housner [6] and other researchers such as Kianoush and Ghaemmaghami [7], Moslemi and Kianoush [8], El Damatty et al [9] and Kianoush and Chen [10]. On the other hand, although the RC pedestal is an important part of the elevated water tank structure, their seismic response has been the subject of only a handful of research studies.…”

Soil–structure interaction analysis of a FPS-isolated structure using finite element model

“…The most common soilstructure interaction (SSI) approach is based on the "added motion" formulation by Clough and Penzien [20]. This approximation is mathematically simple, theoretically accurate, and is easy to use within an finite element method for analyzing a linear system in time domain [21]. On this basis, to account for the soil-structure interaction, it is necessary to apply the inertial loads only to the structure and not to the soil foundation.…”

Tuning mass of internal flexible wall to reduce seismic demand on exterior walls of liquid storage tanks

“…They also developed a mechanical model that accounts for wall flexibility. Kianoush and Ghaemmaghami [15] developing a 3D model accounting for wall and soil flexibility explored the effect of soilstructure-liquid on the sloshing response for different ground motions.…”
