2021-11-15  The 7-story building was tested on the 8 m × 8 m shake table at the NCREE’s Tainan laboratory (Fig. 1a). One far-field and one near-fault ground motion record were generated by the shake table. Moreover, the near-fault ground motion record was scaled to four intensities with the aim of ultimately collapsing the 7-story building.

Seismic behavior of pile in liquefiable soil ground by ...

Dramatic failure of pile foundations caused by the soil liquefaction was founded and leading to many studies on the seismic behavior of pile. The failures were often accompanied with settlement, lateral displacement and tilting of superstructures. Therefore soil-structure interaction effects must be properly considered in the design of pile.
