“…Although this variable was less studied than air temperature or precipitation, the understanding of the SWS evolution is of great relevance for both productive activities and ecological preservation. Changes in WS regimes are important for coastal erosion (Dragani et al ., 2013; Knorr, 2013), air pollution potential (Gassmann and Mazzeo, 2000), forest and community infrastructure protection (Jungo et al ., 2002), surface energy balance (Rayner, 2007), building construction (Cechet and Sanabria, 2010; Cechet and Sanabria, 2012; Tapajós et al ., 2016), maritime activities (Caires and Sterl, 2005), and wind energy production (Barros, 1983; McVicar et al ., 2008; Cross et al ., 2015). Another important activity for which changes in SWS has a great impact is agriculture production, since it is a driver of evapotranspiration in agricultural systems (de la Casa and Ovando, 2016; Liuzzo et al ., 2016).…”

Surface and upper‐level wind speed changes were analysed for several weather stations distributed throughout Argentina from 1990 to 2020. Both annual and seasonal wind speed trends were estimated for individual surface stations and available rawinsonde data. In order to explore the nature of these changes, different percentile time series were evaluated. NCEP/NCAR and ERA5 data were also assessed to verify how these long‐term changes are represented by the different reanalysis time series. A significant decline in measured surface wind speed is observed for most stations, with a reduction up to 13%·decade−1 in some of them. Despite differences on each station's wind speed distributions due to regional characteristics, the estimated trends were mostly negative for the annual 75th and 95th percentile time series. Upper‐level stations registered positive trends especially in the upper troposphere (200 hPa) in northern Argentina, while Patagonia's wind profile showed significant positive wind speed trends at most levels. Reanalysis data have severe limitations to reproduce the observed behaviour in the near‐surface levels, but managed to generate adequate estimates for the medium to high troposphere.

“…Na literatura são relatados vários exemplos nos quais a ação do vento é apontada como a causa de inúmeros acidentes estruturais (SHA; MALINOV, 2014;MIANG et al, 2016;SOLARI, 2019). Nesse caso, o colapso progressivo é um mecanismo de ruína parcial ou total de uma estrutura provocado pela falha localizada de um elemento estrutural primário levando à redistribuição das cargas para os elementos do entorno, os quais também podem vir a ruir (TAPAJOS et al, 2016).…”

Os desastres em edificações devidos à ação do vento ocorrem com frequência e, na maioria dos casos, são atribuídos a ventos incomuns quando, na verdade, as causas são outras. Anualmente, embora seja grande o número de eventos dessa natureza, a sua maioria não é divulgada e nem a sua origem é investigada. Este trabalho trata dos fatores aerodinâmicos e das causas estruturais em acidentes causados pelo vento em edificações. A metodologia utilizada foi uma discussão individual sobre a influência dos aspectos aerodinâmicos. Além disso, foi feita uma análise aerodinâmica da edificação durante o processo de construção, bem como os efeitos de vizinhança na carga média de vento. Da mesma forma, as reformas na edificação foram tratadas como sendo outra possível causa de acidentes por vento nas estruturas. Finalmente, as causas estruturais do colapso do vento em edifícios, com foco nos erros de projeto. Este estudo pode orientar a elaboração de um guia de apoio a fim de identificar os riscos do projeto, mitigá-los e, até mesmo, eliminar os efeitos adversos causados pela ação do vento sobre as edificações. Palavras-chave: acidentes em edificações; ação do vento; fatores aerodinâmicos; causas estruturais.

“…For example, January 2011, a residential building called Real Class, with 13,400 m² area and about 105 m high, which was under construction in the city of in the city of Belem, Para, Brazil collapsed during a heavy rain, where intense winds were registered in the city. After different studies carried out about the case, it was showed that the wind load was not properly considered in the design [46]. Most wind damage to buildings occurs during strong winds, the high-rise buildings are built to sustain extreme wind loads within an expected long lifespan.…”

Extreme Events design and Mitigation Methods: A Review

Recently, extreme events have highlighted their potentially tragic effects on structural and infrastructure systems. Resilience of the Community to these extreme vents is an important issue of increasing more concern for developing design methods. Such extreme events scenarios involve many uncertainties, such as the intensity, location, and period. The extreme events may include those caused by various natural or manmade hazards, such as earthquake, strong winds, fire, blast, etc. Compared to other events, earthquake and wind are particularly critical due to their significant threats to the global structure performance and more challenges for design. Researchers have recognized that proper evaluation, modeling, and assessment of the effects of extreme events are fundamental to ensure the desired performance of structures. Therefore, the concern for developing appropriate methodologies to evaluate and design structures that can withstand the effects of extreme events has become a very active field of research in recent years. Improvement of building codes and development of new strategies are needed to mitigate the disastrous effects of extreme events. This paper presents a comprehensive review of literature surrounding designing building structures for extreme events. First, a general overview of the extreme events design and different objectives of approaches is conducted. Furthermore, a review related literature surrounding designing for earthquake resistance guidelines is presented, also highlights Performance-Based Seismic Design objectives. The available literature includes many studies for the provisions included in different design codes (China, United States and Europe). A review of literature related to wind resistance design with an overview of Performance Based Wind Design of building design method for the control of winds impacting on building structures is also presented.
