This study is to clarify the shear resisting mechanism and establish a shear strength evaluation method for mud-plastered walls through shear loading tests of mud-plastered wall specimens. Since two failure modes were observed throughout the tests, two shear resisting mechanisms were established. Therefore, the minimum value among the strengths corresponding to these two mechanisms was taken as the shear strength of the mud-plastered wall. Taking into account the compressive and tensile strength of mud, the evaluation method based on the shear resisting mechanisms for mud-plastered walls provided a good estimation of the shear strength.
