Recently, a lot more disasters in the temporary structures happen because the stabilities of the temporary structures are disregarded by the reduction of the unit cost, using defective materials, the existing materials and so on. Pipe supports, which are one of the temporary structures, are basically used for the most constructing works such as buildings, bridges, plants and so on. In the most sites, adequate support installations of the pipe supports have not been performed although the presence of the guideline legally and institutionally. In this study, therefore, the collapse accidents of the pipe supports were investigated on the basis of theoretical analysis as well as the buckling tests by simulating the site support condition. Both the theocratical analysis and test results show that the buckling load in the fixed ends is at least 4 times larger than one in the pinned ends. This results will be utilized for safety assurance as well as accident prevention the in the field application.
