“…This is in line with classical setup arrangements for literature experimental studies on curtain wall components, and even numerical investigation for vertical glass members [25,[60][61][62]. When possible, however, more complex setup configurations should be necessarily taken into account even for vertical load-bearing elements [63]. The vertical ground components should be definitely included for horizontal glass members (like slabs, roofs, or walkways that are sensitive to vertical vibrations [64]), in the same way of other constructional systems [65][66][67].…”

Given the growing spread of glass as a construction material, the knowledge of structural response must be ensured, especially under dynamic accidental loads. In this regard, an increasingly popular method to probabilistically characterize the seismic response of a given structure is based on the use of “fragility” or “seismic vulnerability” curves. Most existing applications, however, typically refer to construction and structural members composed of traditional building materials. The present study extends and adapts such a calculation method to innovative structural glass systems, which are characterized by specific material properties and expected damage mechanisms, restraint details, and dynamic features. Suitable Engineering Demand Parameters (EDPs) for seismic design are thus required. In this paper, a major advantage is represented by the use of Cloud Analysis in the Cornell’s reliability method, for the seismic assessment of two different case-study glass systems. Cloud Analysis is known to represent a simple and immediate tool to analytically investigate a given (glass) structure by taking into account variations in seismic motions and uncertainties of structural parameters. Such a method is exploited by means of detailed three-dimensional (3D) Finite Element (FE) numerical models and non-linear dynamic analyses (ABAQUS/Standard). Critical issues and typical failure mechanisms for in-plane seismically loaded glass systems are discussed. The validity of reference EDPs are addressed for the examined solutions. Based on a broad seismic investigation (60 records in total), fragility curves are developed from parametric results, so as to support a multi-hazard performance-based design (PBD) procedure.

“…In a synthesis framework, developed through the critical analysis of systems equipped with these devices, the hypothesis was put forward to evaluate the capacity of the façade to act as an energy absorption device [33], assuming the optimal value of the properties of the façade dampers. It is necessary, therefore, to advance knowledge in the systems of connections that move in the elastic-plastic field to guarantee, in-service conditions, their functionality, not only for the environmental requirements that influence the correct use of the building but also and above all to ensure the safety of the occupants.…”

The research for emerging and disruptive new materials and advanced technologies is a driver of technological innovation in both industry and academia. In this work, the authors present some parts of the results of their research and investigation. The experimental research of advanced materials is a constantly evolving field, concerning the need to respond to increasingly advanced technical performance, even in the construction sector and specifically for Building Envelopes. In this context, the contribution concerns ongoing experimental research, which investigates the dynamic behavior of non-structural elements of the Facade subjected to the action of the earthquake. The results of the investigations conducted so far aim to increase innovation in the field of advanced materials for extreme applications, for the constraints on the implementation of the technologies (increasing element sizes, higher mechanical strengths, better performance), exploiting the superelastic effect (SE) and the shape memory effect (SME). Thus, it seems clear that the potential of the two unique properties for Facade Design applications is a valuable tool for investigating dynamic behaviors that exist in nature as well.

This paper details the comprehensive activities conducted in a laboratory setting to assess the structural health monitoring (SHM) of prefabricated building envelopes. Integrating sensors into building components like curtain wall facades poses challenges but offers opportunities for monitoring structural health, requiring compliance with regulatory standards. The research investigates the possibility of defining a kit of conventional and multi-parameter sensors integrated within the building envelope to monitor its behavior during the performance test conducted. The kit of sensors also includes Fiber Optic Sensors for effectively monitoring building envelope behavior and structural integrity. In this context, the European project InComEss (H2020-GA862597) aims to define a stand-alone solution for SHM using Piezoelectric Energy Harvesting Systems (PE-EHS) for façade monitoring through FBG/FOS system. After analyzing the main façade structural stress, a series of FBGs, accelerometers, and force washers were integrated within a 1:1 scale façade prototype and tested in a laboratory following the test sequence parameters required by the curtain wall standard EN 13830. The data collected were analyzed with the aim of monitoring the façade behavior before and after the tests. The results show that the façade’s performance passed the assessing test criteria without reporting any damages. In addition, the outcomes demonstrated the effectiveness of the defined kit of multi-parameter sensors for the building envelope’s SHM.
