Projects : Task Order 10

SUMMARY

Improved Procedures for Characterizing and Modeling Soil-Structure Interaction for Performance-Based Seismic Engineering

The primary objective of this task is to develop guidance for implementing soil-structure interaction in response history analyses, such that input ground motions accurately reflect both site geotechnical conditions and foundation impedance associated with the building under consideration. The project should also identify areas of research that are needed to further improve the guidance that is developed.
