Risk analysis of bridge falsework cuplok systems
2017
AbstractBridge falsework systems are one of the most common temporary structures used to support the formwork during the construction of concrete bridges. In this paper, the development of a risk analysis of selected bridge falsework structures using the Cuplok® system is presented by means of a risk-informed structural design methodology based on newly developed structural robustness and structural fragility indices. Illustrative examples are given detailing the steps and calculations needed, including consideration of model and statistical uncertainties, and the results obtained are discussed. Furthermore, strategies for decreasing risks are presented and risks are determined for a reference (baseline) scenario and one selected alternative (improved) scenario and later evaluated against proper risk criteria. For the cases analysed, it is concluded that if the cost of the permanent structure considerably exceeds the cost of the temporary structure, which is often the case, the extent of improvements in t...
