Construction Method and Performance of Bugis Traditional House in Wind Disasters

Bugis ethnic in South Sulawesi Province, Indonesia is known as an old tribe who domiciled in the south peninsula of Sulawesi island. They have characteristics of high legacy, culture by the script called lontaraq and life in a traditional stilt house called bola ogi. This house was built in certain methods and become a research problem. The goal of this study is to reveal the construction method and the performance of the Bugis traditional house in facing of wind disaster. The research methods are field observation and in-depth interview. Field observation to reveal the old construction methods of 100 years traditional the Bugis house and its performance in collapse by wind disasters. In-depth interview to strengthen information. The research revealed that Bugis house made of wood and its built-in certain construction methods called mappasituppu. Structure system consists of the main and secondary structure which is joined together rigidly an appropriate hierarchy. The part of the structural member is setting follows natural way. The wind attack saw that building structure collapse step by step depend on its function in the structure as a whole. The lesson from Bugis in construction method is the part of the structure system best to design in the proper strength hierarchy. The strength, structure hierarchy is the maximum strength part of structure equal to the minimum strength of the structure which supports them.
