Abstract:
A new and powerful concept of modeling--the disturbed state concept is applied to the joint case. The disturbed state modeling is based on the assumption that the behavior of the joint, or the behavior at the disturbed state can be expressed by the joint behaviors at its reference states. The reference states include the original state and the critical state. The behavior of the intact joint at the original state is modeled by using a general plasticity joint model developed by Desai and Fishman (1987) with a small modification. The critical state joint is modeled according to observations from shear tests of the joints. The disturbed state joint model developed is capable of describing the hardening and softening behavior of the joint under various stress paths. Verification is made by back predictions and predictions of several series of shear tests. The constants used for back predictions are obtained from those tests back-predicted and the constants used for predictions are from the tests other than the tests predicted. Other important issues such as the size effect of joint sample sizes, the relationship between the roughness of the joint and the parameters in the joint model are also examined.
