Abstract

The disproportionate collapse of building structures is a matter of growing concern. Current design strategies have been shown to have limitations in ensuring adequate robustness when dealing with large initial failures, which can impact the structural safety. This research has developed a novel risk-based strategy to enhance building robustness through segmentation. The proposed methodology involves the identification of an optimal segmentation configuration, with this being based on structural and geometric criteria. Following this, a cost-benefit analysis is developed to evaluate the efficiency of the proposed solution. To illustrate the application of the proposed strategy, a case study has been identified in which the segmentation strategy is applied, and the cost-effectiveness of the identified solution is evaluated.
