Prefabricated mud-shear wall is a mud-shear wall in a compact modular size manufactured in factory work. At construction sites it is constructed simply by being fitted into a wooden frame. It keeps the quality stable even if there is no skilled craftsmen, and it significantly shortens the construction period. In this paper we evaluated structural performance of prefabricated mud-shear wall conducted using static loading test and dynamic shaking table test. It is confirmed that the shear wall has a simple structural mechanism that depends on the single unit, and so its structural performance can be analyzed by a simple model. It is also confirmed that ultrasonic measurement method applied to the prefabricated mud-shear wall is effective for damage evaluation estimation.
