ESTIMATION OF RANGE OF MAXIMUM SHEAR STRESS ON MUD-PLASTERED WALL BASED ON MATERIAL TESTING OF MUD

In this study, estimation of maximum shear stress of mud-plastered wall based on material testing of Nakanuri mud was conducted. Firstly, the range of material strength of Nakanuri mud was investigated from the material testing of 29 kinds of Nakanuri mud all over Japan. Secondly, mud-plastered wall specimens using three Nakanuri muds chosen among the 29 kinds of Nakanuri mud were constructed. From the test results of the shear loading tests of the wall specimens, the relationship between the compressive strength of Nakanuri mud and the maximum shear stress of Nakanuri-layer of the wall specimen was evaluated. Finally, comparison between maximum shear stresses calculated from other test results of various mud-plastered walls and the shear stresses from this test results was conducted.
