“…Due to its sensitive nature and the probability of defacing, increasing the risks, and/or stirring up the aesthetical sight due to the transparent nature of the glass, DT methods may not be of use in structures composed of glass elements. Amongst the NDT failure detection approaches, DIC [28,29], EPMA, IP [30,31], LA-ICP-MS [5], UT [32], etc are the commercially available methods for failure detection inside the glass elements. Due to the particular characteristics of ceramics and glass, NDT methods alone may not provide a panacea for early-stage failures, surface flaws, scratches, and/or other types of defects.…”

“…This section surveys the methodologies of failure detection along with the novel approaches of IP to evaluate the status of glass structures. IP is a CAE instrument regarding the provided data in the literature is in its early stage for use in glass structures [29][30][31]. IP propounds the sub-branch of NDT approaches, which due to its vast sphere of application and more privileged practical results have a profound use and efficacious background in damage detection aims and lead to implement it as a discrete detection technique.…”

The concepts behind employing structural health monitoring (SHM) to the glass structures are in their early stages. While limited information by the application of SHM on glass-made elements could obtain through the literature, recent technological advances enrich the state of the art around the glass elements. As yet because of the novelty in both using SHM and the application of LGs for structural purposes, the historical background around the application of SHM on glass elements doesn't exceed 20 years, and the novelty of the concepts around the LGs may be even more. With this in mind, the demanded assessments have to be incept from the very basis of both the glass and SHM sciences to place the stepping stones of the fundamental stage, which would be a platform for the extending evaluations of glass elements at higher levels. This study is an endeavor to bring forward the available approaches for elaborating SHM on structural elements composed of glass with an emphasis on glass façades. According to the outcomes, the requirement for early detection due to its brittle content proffers structural health monitoring as the limited available alternatives for damage detection of the systems composed of it.

“…In the last decade, the building construction sector has shown an increased use of load-bearing building members composed of timber and glass. The first applications and research efforts (see [1][2][3][4]) were focused on composite beams. Later, the attention of researchers progressively moved towards the definition of novel timber-glass solutions for curtain walls and enclosures to cover large surfaces and also offer enhanced load-bearing performance in buildings [5,6].…”

Thermal and Energy-Efficiency Assessment of Hybrid CLT–glass Façade Elements

Façade elements are a building component that satisfies multiple performance parameters. Among other things, “advanced façades” take advantage of hybrid solutions, such as assembling laminated materials. In addition to the enhanced mechanical properties that are typical of optimally composed hybrid structural components, these systems are energy-efficient, durable, and offer lighting comfort and optimal thermal performance, an example of which is the structural solution developed in collaboration with the University of Zagreb and the University of Ljubljana within the Croatian Science Foundation VETROLIGNUM project. The design concept involves the mechanical interaction of timber and glass load-bearing members without sealing or bonding the glass-to-timber surfaces. Following earlier research efforts devoted to the structural analysis and optimization of thus-assembled hybrid Cross-Laminated Timber (CLT)-glass façade elements, in this paper, special focus is given to a thermal and energy performance investigation under ordinary operational conditions. A simplified numerical model representative of a full-size building is first presented by taking advantage of continuous ambient records from a Live-Lab mock-up facility in Zagreb. Afterwards, a more detailed Finite Element (FE) numerical analysis is carried out at the component level to further explore the potential of CLT–glass façade elements. The collected numerical results show that CLT–glass composite panels can offer stable and promising thermal performance for façades similar to national and European standard requirements.

“…In the last decade, there has been a progressive development of load-bearing building components composed of timber and glass, firstly beams [1][2][3][4]. Later, even more attention has been dedicated to curtain wall applications, where wide surfaces must be covered and enhanced load-bearing performances/deformation capacities must be satisfied, especially under extreme design loads such as earthquakes [5,6].…”

Facade elements are known to represent a building component with multiple performance parameters to satisfy. Among others, "advanced facades" take advantage of hybrid solutions, like the assemblage of laminated materials. In addition to enhanced mechanical properties that are typical of optimally composed hybrid structural components, these systems are energy-efficient, durable, and offer lightening comfort and optimal thermal performance. This is the case of the structural solution developed in joint research efforts of the University of Zagreb and the University of Ljubljana, within the Croatian Science Foundation VETROLIGNUM project. The design concept involves the mechanical interaction of timber and glass load-bearing members, without sealing or bonded glass-to-timber surfaces. Laminated glass infilled timber frames are recognized as a new generation of structural members with relevant load-carrying capacity (and especially the enhancement of earthquake resistance of framed systems), but also energy-efficient and cost-effective solutions. In this paper, a special focus is then dedicated to the thermal performance assessment of these innovative CLT-glass facade modules under ordinary operational conditions. Numerical modelling of a full-scale mock-up building is first presented, by taking advantage of continuous ambient records of environmental and thermal comfort parameters. Afterward, a more detailed Finite Element (FE) numerical analysis is carried out at the component level (CLT-glass facade element). The numerical results show that the even the use of a bare / thermally no optimized CLT-glass composite panel for facade systems can be energy efficient and offer stable thermal performances, that are almost in line with national and European standards requirements.
