PROPOSE OF DECAY-ACCELERATION METHOD FOR REAL SIZE COLUMN-SILL JOINT AND EVALUATION OF STRENGTH PROPERTIES

摘要

It is important to evaluate the existing strength of decayed structural members and joints in use for long term safety. In this study, the decay-acceleration method for the real size column-sill joints was proposed and the pull-out strength properties were evaluated. As a result, it was possible to prepare the partial decayed specimens of real size column-sill joint attacked by brown rot fungi. In this case, no significant differences of maximum load due to the duration of decay were shown. It was seemed that the smaller the maximum load was, the larger the penetration depth using Pilodyn® was.
