摘要

This report shows the results of a relative-story displacement oscillation test conducted on vertical piping using thin-walled stainless steel pipes.The main purpose of this experiment is to investigate the influence of relative-story displacement oscillation on the vertical pipes with various diameters and supporting methods.In the previous research, the relative-story displacement oscillation test conducted on a vertical piping using thin-walled stainless steel pipes was reported, whereas no report on the piping that have various diameters and supporting methods.The shaking table test was conducted for pipes combined 14 kinds of vertical pipings and 2 kinds of piping support methods.In the case of simply supported, displacement of a small-sized piping with branch increased.The displacement of the vertical pipe without fitting is almost the same as the piping without branch piping.In addition, displacements of the fitting of the pipe was amplified, and large response displacement of the branch pipe connecting to the vertical pipe also occurred.It is apt to occure vibration when a small-sized piping is simply supported, which is close to actual constructional supporting.For this case, it needs consideration taking such measure as narraw supporting distance.In actual buildings, a vertical pipes without branch are used in many cases, where the simply support is commonly used.In addition, because response displacement of the branch pipe also occurs, it is nesesarry to choose the fitting that withstand the large repeated displacement between the vertical pipe and the branch.
