Load path redundancy as a protection measure - Phase 1

Load path redundancy has proved an effective design strategy to mitigate against disproportionate collapse when structural members are lost due to intentional extreme events. Numerical simulations were conducted and need validation before developing general guidance for stakeholders. Component level response is well understood, however, system response predictions depend on the accuracy of connection or joint modeling. Uncertainties still exist in this understanding and the degree of the fidelity of modelling required still needs quantifying.
