“…It is noted that the approach of performing progressive collapse analyses of steel frames using various intensities of wind loading is followed also by Gerasimidis and Baniotopoulos (2011). Wind loads are also taken into account in progressive collapse analyses by Mohamed (2009), while lateral loads calculated as a percentage of gravity loads are applied by Gerasimidis et al (2014) and Dinu, Dubina, and Marginean (2014).…”

This work is concerned with the explicit treatment of progressive collapse resistance within the structural design process. Progressive collapse resistance is associated with the damage tolerance of a structural system and controls the ability of the system to sustain local damage by absorbing the potential of triggering system collapse and suffering disproportionally large consequences. This work focuses on the design of elastoplastic steel frames. The measure of progressive collapse resistance employed is expressed as a ratio comparing the limit loads obtained with elastoplastic analyses of the intact structure and of an artificially damaged structure ('damage' is caused by the notional removal of a column from the intact structure). This measure is used to incorporate a constraint on progressive collapse resistance into a structural design optimisation formulation, which -in its classical form -takes only standard design code constraints into account and aims at minimising the structural cost. The developed optimisation approach is capable of producing cost-effective structural designs with acceptable system damage tolerance. By enforcing the satisfaction of the additional design requirement on progressive collapse resistance, structural cost is inevitably increased due to the need for extra material. This increase is quantitatively explored with the presented structural design optimisation approach.

“…21b). Some of the latest and most important works on simulating complete building structures by this technique are those by: Sasani et al [220], Galal and El-Sawy [26], Salem et al [262], Helmy et al [80,263,264], Khalil [265], Hefez et al [266], Dinu et al [267], Kim and Wee [268], Ehab et al [269], and Attia et al [270]. In all these studies the simulations were able to follow the structures until collapse after a sudden column removal.…”

“…They found a close correlation between the AEM model and reality. Dinu et al (2015) use the AEM to evaluate the structural robustness of multi-storey steel-frame buildings. Coffield and Adeli (2016) showed that specific load exposures such as blast may be modelled with the AEM.…”

Timber buildings are increasing in their dimensions. Structural robustness is imperative for all buildings and specifically important for tall buildings. Lives can be saved if disproportionate collapse can be avoided after a catastrophic event (e.g. accident, terrorism). The literature about robustness is comprehensive concerning concrete and steel buildings, but is rather limited regarding timber. This paper reviews robustness in general and robustness of timber buildings in particular. Robustness is an intrinsic structural property, enhancing global tolerance to local failures, regardless of the cause. A deterministic approach to assess robustness is to remove certain loadbearing elements from the structure and compare the consequences to given limits. Design methods for robustness may be direct by assessing effects of local failure, or indirect by following guidelines. For robust timber buildings, the connections are the key aspects. Usually, metal connectors may provide the required joint ductility. For robust light timber-frame construction, rim beams may be designed. For timber posts and beams and cross laminated timber, guidance regarding robustness is scarce, but in some aspects they seem to be similar to steel frames and precast concrete. Future research should assess the capacity of connections, and evaluate the adequacy of seismic connectors for robust timber buildings.
