Abstract
Recently, interest on the performance of the construction temporary equipment have been greatly increased. Since the application of the 'Performance Test Code' for the equipment in 1992 according to the Industrial Safety and Health Act, a basic study of Steel Pipe Supports have been carried out for the last 2 years based on the Performance Test Results. The present code specification for the Steel Pipe Supports and research status are introduced. So far, total 849 specimen have been examined on their outer and inner pipe's length, thickness, their overlapping length, and their load carrying capacities. The test was conducted separately into two groups - used and new equipment, and it was found that the used ones revealed a decrease on their load carrying capacity, almost $\small{10\%}$ compared to the new ones. Considering this fact, it is strongly recommended to ensure the quality of the equipment before use at the jobsite. First of all, based on this basic investigation, the statistical values on the Steel Pipe Supports are suggested and further analysis on the effect of each component is in progress. It is, however, expected that this report can be used as a basic information on the Steel Pipe Supports.
