In cases of wooden structure and wooden house installed on the outside, metal goods used for basic connection are usually screw bolts, strainless nails and general iron nails. As metal connections on wood are directly exposed to exterior environment, friction resistibility of nails on metal connections declines and continual defects on this are generated and maintenance for it is required. However, experiments and analyses for preparing basic data for improvement of the problems have been not conducted so far and wooden structures with defects are abandoned. Accordingly, by analyzing friction resistibility of connections by each kind of woods and metal goods, the study aims to suggest to use metal goods appropriately by kinds of woods and manufacture conditions with analysis on characteristics of resistibility of extracting nails for solving such problems and to secure basic data for establishing maintenance, repair and reinforcement plans.
