Abstract
Ever since the introduction of high strength steel pipe strut(POSTRUT) in 2008, there has been over 50 applications domestically. The merits of construction period reduction and cost savings have been well reported abroad in countries such as America, Europe and China but ever in domestic projects or ground condidtions. 25 actual construction projects were investigated and statistically analyzed to evaluate the quantitative effects of POSTRUT. Also the construction projects along with the cautions that should be taken and the structural behavior differences between POSTRUT and H-section struts are briefly described in this paper.
