An online technical talk on research into designing and constructing concrete structures to withstand extreme events

It is widely recognised that in order to design and construct resilient buildings and infrastructure, able to withstand and recover from extreme events, structural robustness needs to be considered to limit the extent of damage or even progressive collapse after local failure of some of its structural members.

Design codes in Europe, America and Asia adopt different methods for robustness design including the Alternative Load Path (ALP) method in which a minimum level of robustness is verified using the notional column removal concept.

Recent findings from real-scale building tests from a collaboration between Universidad Politécnica de Valencia (Spain) and University of Surrey (UK) are presented. The tests use realistic gravity loads adopted in design for accidental load combinations.

The results show the dynamic response after sudden column removal and the development of different alternative load paths including Vierendeel action and the activation of vertical ties and diagonal struts in the case where masonry infill walls were also used.

The results were used to validate theoretical and numerical models developed in this project. Design recommendations derived from this research are discussed and some design examples are also illustrated which demonstrate that relatively simple calculations can be performed during the conceptual and detail design phases to improve robustness.
