An adjusted partial factor method for temporary structures compatible with the Eurocode framework
article
The Eurocodes currently do not provide a coherent, straightforward framework for the semi-probabilistic design of temporary structures. Besides the need for suitable target reliability levels, a coherent definition of partial factors is needed in order to adjust them according to the chosen target reliability level and the intended reference period of the temporary structure. Further, attention should be given to the coherency with current Eurocodes in order to avoid conceptual discrepancies between the design of long-term and temporary structures. A framework is presented here in order to derive appropriate partial factors for temporary structures, considering a simplified level II approach. The target reliability level and the reference period are considered as parameters and can be adjusted, so the framework remains valid under alternative economic considerations or requirements for human safety. Further, a set of easy-to-use graphs are provided for implementing the proposed procedure in practical standards. Finally, a framework is presented to adjust the target reliability index, considering human safety and economic criteria in case of temporary structures.
