Abstract
Abstract A significant proportion of performance failures (e.g., structural failure, cost overruns, delays) are due to human error in the construction of in-situ reinforced concrete elements. A Human Reliability Analysis (HRA) model has been developed to simulate the effect of human error on the construction of a reinforced concrete beam. The proposed HRA model incorporates the effect of (i) initial errors (i.e., before engineering inspections) and (ii) errors remaining after engineering inspections. The following typical construction tasks are considered: number and size of reinforcing bars, effective depth of steel reinforcing, beam width, and quality of concrete mix. Human performance models are described for each of these microtasks. It was found that human error leads to a significant loss of structural safety. It was also shown that engineering inspections significantly increased structural reliability, but the resulting structural reliability was still an order of magnitude lower than nominal est...
