A fastener-style tubular steel formwork-support (FTSF) is often used for temporary support during the construction in China for its convenience and applicability. In order to modelling and performing probabilistic analysis of the stability bearing capacity of FTSF, actual data of semi-rigid joint behavior and initial geometric imperfections are needed. However, at present little information on probabilistic models of rotational stiffness and initial geometric imperfections are available in the literature. This paper presents the results of FTSF joint tests. The tests were performed on randomly chosen right-angle couplers to investigate the joint rotational stiffness. The paper also reports the findings from various site measurements of initial geometric imperfections of FTSF. The measurements consist of out of straightness and out-of-plumb of the standards. The statistical probabilistic models of the data are presented in the paper for practical application in probabilistic assessment of FTSF.
