“…Comparing the acquired results of the proposed DSF with others obtained from similar constructive solutions, such as the one analysed by Reyes et al [7], in the present case study and experimental wind assessment the full-scale sample was subjected to a maximum pressure up to 3200 Pa, obtaining a maximum relative displacement of 56.43 mm with 14.20 mm of permanent deformation; in the same test, Reyes et al exposed the outer layer of their ventilated façade case study to a pressure of 1590 Pa, obtaining a maximum mid-height relative displacement of 198 mm, with 87 mm of permanent deformation. For both case studies, when exposed to wind loads, it was proved the high adaptability of flexible DSF systems and the progressive distention of the cables when the lateral load increased; nevertheless, only local damages was evidenced at the end of the tests.…”

“…Therefore, a comprehensive understanding of these factors is essential for designing effective and sustainable façade systems. A recent alternative for DSFs involves the use of flexible elements to support the external cladding components [7]. This variant introduces an innovative approach to the traditional construction method, offering distinct advantages, among which are: adaptability, given that flexible elements can accommodate irregularities in the building's structure, allowing for more versatile and creative designs [8]; a better dynamic response (since the flexibility of these elements enables the cladding system to adapt to external forces, such as wind loads or seismic activity, without compromising its integrity [9][10][11][12]; and, often, an enhanced insulation, because by incorporating flexible elements, the insulation properties of the cladding system can be improved, further enhancing the building's energy efficiency [13].…”

“…Regulatory frameworks play a crucial role in ensuring the safety and performance of DSFs. However, usually, these regulations often focus primarily on structural elements or provide general requirements for various façade components [7,14]. The validation of DSFs involves a comprehensive examination of their components, performance, and interactions.…”

Cable-supported façades represent a novel approach in the design and technology of double skin façades (DSFs). This type of system not only offers flexibility in terms of exterior finishes, but also regulates the access of solar radiation, thereby transforming the appearance of the building in response to varying daylight conditions. However, the structural performance of these façades under wind, impact, and seismic loads remains an active area of research. The study is a groundbreaking work that experimentally evaluates the wind and seismic behaviour of these type of façades. The methodology used for the evaluation of flexible masonry facades includes laboratory tests analysing the individual capacity of the connections and materials of the system under standardized and non-standardized procedures. A full-scale experimental sub-assembly specimen of a representative module of the façade is also subjected to uniformly distributed pressures of wind load tests, as well as hard body and soft body impact tests. The setup considered the border conditions, tension loads, and actual materials. Furthermore, the earthquake assessment includes tests of full-scale specimens subjected to these demands. The results show up to 30% enhanced performance relative to similar systems reported in the literature. Furthermore, research findings facilitated the refinement and redesign of the system components, thereby validating the DSF case study.

Dynamic Characteristics Test and Simplified Calculation Model of Concealed Frame Panel Element

et al. 2022

Hidden frame glass curtain walls are one of the most common curtain wall structure forms. This year, the damage identification of panel elements based on vibration has had the problem of an inconsistent calculation model. In this paper, an experimental study on the dynamic characteristics of two full-scale panel elements is carried out, and the main factors affecting the dynamic characteristics of panel elements are analyzed by using a fine finite element model, and the corresponding simplified calculation model is proposed. The experimental and numerical results show that the structural sealant and frame are the important factors affecting the dynamic characteristics of panel units of hidden frame, and the natural frequency of panel elements can be overestimated by more than 40% if a simply supported boundary is adopted. The effect of structural sealant on glass panels and the supporting frame is mainly a translational constraint. The effect of structural sealant on the rotational constraint of a glass panel can be neglected and simplified as a translational spring model. Using a shell element, a translational spring element and a beam element, respectively, the calculation error of the glass panel, structural sealant and supporting frame is about 5%, which shows good calculation accuracy.
