Abstract: The prestressed self-centering concrete frame joints with angle-high strength bolts-connection (simplified as PTED joints) have good self-centering capacity and energy dissipation capacity. In order to study the restoring force characteristics, the tests of 7 PTED joints were conducted under low cyclic loading. According to the test results, the trilinear skeleton curve model was determined. The theoretical derivations for the key points of the skeleton curves were obtained. The hysteretic restoring force rules for the joints were constructed. The hysteretic restoring force model was established. The calculated results show that the skeleton curves, the established hysteretic restoring force model and the calculated energy dissipation capacity are in good agreement with the experimental results. The effectiveness of the established restoring force model was verified. The established restoring force model can be used for the elastoplastic analysis of the PTED structure.
