摘要

在低周反复加载试验的基础上，对新型石膏混凝土复合墙板进行地震损伤模型研究。在具有垂直孔腔的石膏板肋上沿墙高方向隔一定高度设置水平孔腔，灌注混凝土后形成密柱与梁格构形式的新型石膏混凝土复合墙板。进行了四块新型复合材料墙板的低周反复加载试验，得到新型石膏混凝土复合材料墙板试件的破坏特征、滞回特性、承载能力等抗震性能。依据试验特点，在Park模型及其改进模型的基础上，提出一种不依赖于单调加载试验结果的损伤模型，并考虑了墙体开裂的因素。通过试验结果对比表明，该模型能准确描绘试件损伤的发展历程，对新型石膏混凝土复合墙板试件具有较强的适用性，损伤指标对于开裂位移敏感性较低。研究同样表明，文中提出的新模型对于其他类型的混凝土试件仍能给出较合理的损伤指标。

Abstract

Seismic damage model of the new type of gypsum concrete composite wall is studied based on the low cycle repeated load test. Setting horizontal holes along the high direction of the plaster board with vertical holes already to constitute a new form of gypsum concrete composite wall with the lattice type of dense column and beam after pouring concrete. Low cycle repeated load test of four new type of gypsum concrete composite walls is carried out to obtain their seismic performance such as damage characteristics, hysteretic behavior, bearing capacity and so on. According to the characteristics of the test, proposing a new damage model based on the Park model and its improved models. The new damage model is independent on monotonic loading test results as well as take the wall cracking factors into consideration. Through the comparison of the test results, the new model can accurately describe the damage development of the test pieces. It not only has a strong applicability for the new type of gypsum concrete composite walls but also has a low sensitivity to cracking displacement. The model can still give a reasonable damage index for other types of concrete structures.
