为了探究结构与保温一体化新型复合墙板节点的抗震性能及地震损伤模型，提出了一种采用U型节点配筋形式的新型复合保温墙板节点。设计并制作了6个试验样本。通过工作性能力学试验，研究了该类墙板节点试件的破坏机理、滞回性能、承载能力以及延性系数等指标。另外，通过研究发现，常用的Park损伤模型并不能较好地反映试件损伤发展情况。因此，为了能准确描述新型复合保温墙板节点的地震损伤发展，文中在试验的基础上提出了一类适用于该类试件的改进地震损伤模型。通过实例验证发现，反映出可以利用较多指标对损伤的合理评价，应用前景具有广泛性。
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.
