Abstract :
Human error plays a significant role in the failure of fastener-style tubular steel formwork-support(FTSF) during construction. Making full use of site investigation and references, the laws of human error occurrences during construction were gained. The probabilistic models for slip bearing capacity of right-angle couplers with different bolt tightening torques were obtained through experimental study on right-angle coupler. Finally a procedure based on HRA method was presented to simulate the influence of human error on the capacity of FTSF, which may be used to obtain “realistic” probabilities of FTSF failure.
