| Abstract |
Although Prefabricated Steel Pipe Scaffolding(PSPS) systems are frequently used in domestic construction sites, there are no any comments related to the overall capacity of the PSPS system in the Industrial Safety and Health Act (ISHA) but the ones??describing the testing method and the capacity of the each member of PSPS. So, if we want to use the PSPS systems as shores, it is necessary to know the full capacity of the PSPS system, not the ones of the members but the one of the total PSPS frame. In this study, first, vertical frame members which are the basic elements of the PSPS frame, are tested for finding out its capacity. Second, the load tests about the full strength of the PSPS system are performed in two ways, namely, for the one-story and the two-story PSPS frame. In each case, the centric load(1/2 L) and??the eccentric load (1/4 L, 0 L) tests are carried out, where L is the longer length of the PSPS frame. According to the results of the experiments, first, the load endurance capacity of the one-story PSPS frame are larger than the one of the two-story PSPS frame at the same conditions. Second, the centric load endurance capacity is larger than the one of the eccentricl |
