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.
