EXPERIMENTAL STUDY ON EVALUATION OF MECHANICAL PROPERTIES OF BRICK AND JOINT OF MITSUI TEXTILE INDUSTRY

Abstract

Main purpose of the present study is to apply the earlier proposed failure criterion to the prediction of a failure pattern and strength of an actual historical building brick wall, and then to discuss how to express the deterioration in the criterion. Two series of experiments were carried out. In the first experiment, after conducting a series of single and double shearing test of small specimens, newly fabricated brick walls were tested to check the applicability of the proposed formula. In the second experiment, specimens from actual historical building were tested and the applicability of the formula was examined again. As a result, it was shown that the proposed failure criterion may be used to predict the failure pattern and strength to some extent when bond between a brick and jointing mortar can be well considered in the formula. The bonding rate of the presently tested historical building wall was found to be 0.6 on the average.
