The research is aimed to delineate the effect of relative motions at interface on dynamic response of structures and foundations. It will provide a new and improved understanding of the mechanism of load transfer in dynamic soil-structure interaction as affected by roughness and fluid pressures. It is anticipated the outcome will lead to improved designs of a wide range of geotechnical problems. A new test box will be developed to simulate behavior of saturated sand-concrete interfaces. A comprehensive series of laboratory tests will be performed and used for the development of a constitutive model based on the disturbed state concept and hierarchical plasticity models.

该研究旨在描述界面相对运动对结构和基础动力响应的影响。 它将提供对受粗糙度和流体压力影响的动态土壤-结构相互作用中的载荷传递机制的新的、改进的理解。预计该成果将改进各种岩土工程问题的设计。将开发一种新的测试箱来模拟饱和砂-混凝土界面的行为。将进行一系列全面的实验室测试并用于开发基于扰动状态概念和分层塑性模型的本构模型。
