Abstract

The large use of glass in buildings, and especially the presence of fenestrations and facade systems, represents a potential critical issue for people safety. The brittle nature of glass (with limited elastic deformation and resistance) is often enforced by its use in combination of several secondary components, whose reciprocal interaction and potential damage should be properly assessed. In the case of windows, accordingly, a special care should be spent for glass members but also for the framing system and possible adhesive or mechanical connections. This study aims at exploring the dynamic response and damage sensitivity of traditional glass window systems, based on the experimental derivation of few key material properties and mechanical parameters. To this aim the attention is focused on traditional, in-service windows that belongs to existing residential buildings and are typically sustained by timber frames, through a linear flexible connection. In doing so, major advantage is taken from experimental analysis, both in the static and dynamic field, for whole window assemblies of single components. For comparative purposes, selected window specimens including plastic (PVC) frame members and Insulated Glass Units (IGUs) are also taken into account in the paper. The static characteristics of the windows components are first preliminary derived. The dynamic performance of such a kind of systems is then experimentally explored with the support of modal analysis techniques and hard body impact procedures, including the experimental derivation of stiffness parameters for the frame members and the glass panels. Further assessment of experimental outcomes is finally achieved with the support of Finite Element numerical analyses.
传统在役玻璃窗在动力试验和硬体冲击下的力学试验分析
建筑中玻璃的大量使用,特别是开窗和立面系统的存在,代表了人们安全的潜在关键问题。玻璃的脆性(具有有限的弹性变形和阻力)通常由其与几个次要部件的组合使用而增强,这些次要部件的相互作用和潜在损伤应该得到适当的评估。因此,在窗户的情况下,应该特别注意玻璃构件,也要注意框架系统和可能的粘合剂或机械连接。本研究旨在探索传统玻璃窗系统的动态响应和损伤敏感性,基于几个关键材料性能和力学参数的实验推导。为了实现这一目标,建筑师将注意力集中在传统的、在用的窗户上,这些窗户属于现有的住宅建筑,通常由木框支撑,通过线性的灵活连接。在这样做的过程中,主要的优势是从静态和动态领域的实验分析中获得的,对于单个组件的整个窗口组件。为了进行比较,本文还考虑了包括塑料(PVC)框架构件和绝缘玻璃单元(igu)在内的选定窗口样本。首先对窗口构件的静态特性进行了初步推导。然后,在模态分析技术和硬体碰撞程序的支持下,对此类系统的动态性能进行了实验研究,包括框架成员和玻璃板的刚度参数的实验推导。最后,在有限元数值分析的支持下,对实验结果进行了进一步的评估。
