DEVELOPMENT OF NUMERICAL ANALYSIS FOR JAPANESE MUD WALL

In this paper, I propose the numerical analysis method to calculate the restoring characteristic of Japanese mud plaster wall and its variants. The numerical model of mud plaster wall is composed of frame member for both post and beam, the end springs for the connector of frames, rectangular solid model for mud plaster and contact analysis model between mud plaster and frame. The restoring characteristics of end springs are set using examples from element tests. The smeared crack approach is used for mud plaster solid model as reference. The restoring characteristics of mud plaster solid model are set using examples from both the compression test and the splitting test of mud plaster cylinders. The contact element is composed of 2 springs, which transfers only compression. Three models are employed for the comparison between actual tests and analysis. One is the standard mud plaster wall whose length is 910mm, and height is 2730mm with 3 battens. Another model is the wooden frame with hanging wall. And the other model is a mud plaster wall whose length is 1820mm. The comparison between actual tests and analysis shows that the maximum strength, the skeleton curve and the curve in unloading of mud plaster wall are calculated approximately.
