Estimation of The Mechanical Properties of Mud Shear Walls Subjecting to Lateral Shear Force

In this study, load-deformation relationship of mud shear wall (MSW) was assumed as a combined one which composed of non-linear semi-rigid frame action and non-linear solid wall action. In order to establish mechanical models, at first moment-rotation relationship of “Nuki” joint and mortise-tenon joint were theoretically derived. Then stress-strain relationship of solid mud part with bamboo laths was estimated by truncating load-deformation curve of frame only from that of full MSW. Finally, every data were inputted into non-linear FEM program to analyze three different MSW specimens. In the case of normal MSW, effect of frame was small, while in the case of hanging wall type MSW, the effect of frame joints was remarkable, especially in post yielding range.
