Abstract A new composite wallboard joint of thermal insulation structure using U-shaped reinforcement was put forward to explore the seismic performance and seismic damage model of a new composite wallboard joint of insulation-integrated structure. Six experimental specimens were designed and made. With the low-cycle reversed loading test, the failure characteristics, hysteretic curve, bearing capacity, ductility coefficient and other indicators of this type of wallboard joint were studied. In addition, the research result shows that the commonly used Park damage model cannot reflect the damage development of the specimen. Therefore, an improved seismic damage model suitable for this type of specimen was proposed in this paper on the basis of experiments to accurately describe the development of seismic damage of new composite wallboard joint of thermal insulation structure. Through the case verification and analysis, it shows that this damage model can utilize more indicators to reasonably evaluate the damage, and the application prospect is extensive.
