Evaluation of the Seismic Bearing Capacity of Shallow Foundations Located on the Two-Layered Clayey Soils

Seismic bearing capacity of shallow strip footing embedded in slope resting on two-layered soil

“…q ult is the ultimate bearing capacity of the strip footing. The cases of footings lying on two-layered level ground with the seismic action are compared with the results of Jahani et al (2019), and the comparison is presented in Table 5. It is observed from Table 5 that the results of the present study agree well with those of previous studies.…”

Numerical Investigations on Seismic Bearing Capacity of Interfering Strip Footings

“…In the literature, several researchers have followed a simple approach by incorporating pseudo-static seismic forces to study the reduction in the bearing capacity of an isolated strip footing. In this field, the available theoretical researches are mostly based on (1) the limit-equilibrium method (Budhu & Al-Karni (1993); Choudhury & Rao (2005); Jahani et al (2019); ; Pain et al (2016); Richards et al (1993); Saha & Ghosh (2015); Sarma & Chen (1995); Sarma & Iossifelis (1990)); (2) the upper-bound theorem of limit analysis (Dormieux & Pecker (1995); Ghosh (2008); Paolucci & Pecker (1997); Soubra (1999)); (3) the lower-bound theorem of limit analysis (Chakraborty & Mahesh (2016); Kumar & Chakraborty (2013)); and (4) the method of stress characteristics (Cascone & Casablanca (2016); Keshavarz & Nemati (2017); Kumar & Mohan Rao (2002). In addition, there exist limited experimental and numerical studies related to the estimation of the seismic bearing capacity of an isolated strip footing (Huang (2019); Knappett et al (2006); Luo et al (2019); Pane et al (2016); Shafiee & Jahanandish (2010); Zeng & Steedma (1998)).…”
