In this paper, the loading tests of wooden frames with mad plaster wall and their numerical analysis are reported. Three mud plaster are made of 3 different blend of clay, sand, and straw. Results are as follows: 1) if there is no separation phenomenon of mud plaster from a lath, the horizontal resistant force characteristics of wooden frames with mud plaster wall are close to calculated by proposed method. 2) The hypothesis of mud plaster separation phenomenon represents that the tensile strength of mud plaster gives the separation horizontal load of the wooden frames with mud plaster.
