Abstract:There classical restoring force models for flexural, shear and sliding deformations were summarized. The modification and improvement of classical models in recent years were presented. A restoring force model which can consider the varying axial and lateral loads was descripted. Combining with existing research results, two main development directions of restoring force models were pointed out. And the issues that need to be solved in further research were put forward.
