A STUDY ON SHEAR RESISTING MECHANISM OF MUD-PLASTERED WALLS BY NUMERICAL ANALYSIS

The mud-plastered wall has come to be regarded as an important earthquake resisting element for Japanese traditional houses through recent researches. However, because its materials, which are completely natural resources, are gathered around the constructing place and every district in Japan has its own constructing method, shear loading tests of mud-plastered walls are needed to clarify the shear resisting performance of a mud-plastered wall in every district. In this study, to evaluate the shear resisting performance of every mud-plastered wall in Japan at lower cost, the numerical analysis model of mud-plastered walls by means of Rigid bodies-spring model (RBSM) are discussed. Moreover, the validity of the former proposed shear resisting mechanisms to estimate the shear strength for mud-plastered walls are discussed from the analysis results.
