WebConventional seismic passive pressures of earth structures are based on a linear failure criterion in earthquake zones. However, experimental evidence shows that the strength envelopes are nonlinear WebThe displacement of an ERS will reduce the dynamic forces and soil pressure on the ERS during a seismic event. The more an ERS moves, the less seismic lateral earth pressures on the ERS. In the seismic design of ERS, there is the concept of the “seismic fuse” also known as horizontal yield seismic coefficient.
