碩士 === 國立成功大學 === 建築(工程)學系 === 85 === The structures of ancient time''s buildings are almost made of wood. Now in Taiwan， there are almost 64％ historical buildings that are made of wood. The wooden buildings have to face one important problem that is repairing.According to the interviews and observations，during the process of historical building''s repairing，when it has to use the adhesives or to strengthen，at present the repairers of historical buildings always use one or two kinds of adhesives. They seldem choose other kinds of wooden adhesives. Regarding to the adherent and repairable ability of these chemical adhesives，we only know it from the oral experiences. There are no actual records or analysises for repairers to find the assure viewpoint in using the wooden adhesives.This research is through interviewing the concerning businessmen and markets. We choose the usually used woods in historical wooden structure buildings and the wooden adhesives to make the following experiments.（1）The shear strength of the adhesives between the radial section of wood and wooden adhesives under the normal condition ，acid rain or the ultraviolet lamps.（2）The tensile strength of the adhesives between the cross section of wood and wooden adhesives.（3）The influences of the different erasing times and combining ways for the connecting strength of the cross section. Wish we offer it in the repairing and strengthening of wooden buildings to have the best choice in wooden adhesives.
