Abstract

In recent years, glass, and glass facades are increasingly used as part of building structures. Due to its functions, glass is used in commercial, residential, or strategic buildings, such as airports, stations, or offices. However, window system is subject to several forms of the load. This can be an extreme load in the form of an explosion, an earthquake, or other types of loads, such as their wind load, or dynamic impact. In the article, we focused on an overview of several norms, standards, and research that address the issue of resilience of window systems. The aim of the article was to identify the parameters that are examined in various tests in the standards. The investigated parameters of windows in a manual attempt at burglary, impact test, and explosion were discussed in the article.

Windows or glass facades are part of every building because they perform many functions as good insulation properties, the lighting of the rooms, and the safety of the interiors of buildings [1]

Summary

Introduction

Windows or glass facades are part of every building because they perform many functions as good insulation properties, the lighting of the rooms, and the safety of the interiors of buildings [1]. The basic parts of any type of window include the frame, seal, and glazing. The glass seal is usually made with sealant. Structural sealant is commonly used to attach a glass sheet to a frame. All windows systems (glass and frame) have to resist besides the wind load even accidental loads: impact (in standards called burglary resistance) and blast loads. Glass is a brittle material and usually fails suddenly and catastrophically [3]. This is mainly due to its atomic structure and the resulting sensitivity to deficiencies and inability to resist crack propagation. As soon as the cracks reach a critical value, the glass may suddenly fail. AN glass has a low value of tensile strength (45MPa). For normal design purposes a breaking strength of 45 MPa (based on 95 % of samples) [4]
