Study on the restoring force model for the high-speed railway CRTS III Slab Ballastless Track
The China Railway Track System III (CRTS III) Slab Ballastless Track (SBT) is currently one of China's most widely used track structures. The elastic–plastic restoring force hysteresis model of CRTS III SBT is the primary problem that should be solved for the elastic–plastic seismic response analysis of high-speed railway (HSR) CRTS III SBT systems. To study the elastic–plastic restoring force hysteretic model of CRTS III SBT, four CRTS III SBT specimens were designed in this study and subjected to low-cycle reciprocating load tests. The effects of different thickness of rubber pad on the hysteretic curve, skeleton curve, and other performance of CRTS III SBT specimens were determined. In addition, the restoring force characteristics and hysteretic trends of CRTS III SBT specimens were ascertained. Furthermore, a load–displacement restoring force model for CRTS III SBT was built. Its results were compared with the test results, thus validating the load–displacement restoring force model rationality. The load–displacement restoring force model developed in this study is simple to calculate, laying a solid foundation for analyzing the elastic–plastic seismic responses of HSR CRTS III SBT systems.
