Abstract

Indices like cyclic damage and factor of safety are often used to quantify stability of soil systems subjected to earthquake loads. The methods used to obtain these indices are described; the relationship between cyclic damage and factor of safety through the concept of uniform stress equivalent time history is explored. For evaluation of a soil system design, the use of a direct approach is proposed. Evaluation of this approach by a simulation study is outlined. This approach, can use response spectra directly as seismic design input, and it provides an acceptable procedure for seismic stability prediction of soil systems.

Seismic Stability Indices of Earth Structure

St. Louis, Missouri

Indices like cyclic damage and factor of safety are often used to quantify stability of soil systems subjected to earthquake loads. The methods used to obtain these indices are described; the relationship between cyclic damage and factor of safety through the concept of uniform stress equivalent time history is explored. For evaluation of a soil system design, the use of a direct approach is proposed. Evaluation of this approach by a simulation study is outlined. This approach, can use response spectra directly as seismic design input, and it provides an acceptable procedure for seismic stability prediction of soil systems.
