The impact of a PEER funded research project “Implementation and Validation of PM4Sand in OpenSees” is highlighted below. The project Principal Investigator is Pedro Arduino, Professor, Department of Civil & Environmental Engineering, University of Washington. The research team includes Long Chen, PhD Graduate student, University of Washington.
Prediction of the behavior of liquefiable soils is important for design. Key to accomplish this goal is to have an advanced model. Existing models usually require many input parameters and those parameters usually require a great effort to calibrate. The PM4Sand model was introduced to provide relatively good approximation and easy calibration process. An implemented PM4Sand model in OpenSees would provide a reliable and free tool to simulate behavior of liquefiable soils. This tool can be both used by researchers and engineers in practice.
