Annealed glass suffers from stress corrosion, i.e., the decrease of the tensile strength over time, under load. The classical theory to account for this phenomenology involves the chemical reaction of water with silica which replaces strong chemical bonds with weaker ones, thus leading to sub-critical growth of the superficial flaws. In the present work, an […]

Modern standards and codes of design practice require the evaluation of the response of glazed surfaces with respect to impulsive dynamic actions in order to avoid brittle failure. The soft-body impact test allows to reproduce the effect of the accidental impacts of human. This is a free-boundary value problem, since the imprint of the impinging […]

Chemical toughening is an option to substantially increase the mechanical strength and temperature resistance of structural glass. Although thermal tempering is still the common used procedure in construction industry, the advantages of chemical toughening are significant. While prestresses of thermally toughened glasses can reach values of up to 100 MPa, values of 200 MPa or […]

The edge strength of annealed glass is an essential aspect in design. A common problem is the failure of the edge due to thermally induced stresses. The edge strength of annealed glass is affected by cutting and further processing. Thermally treated glass exhibit higher edge strength, but these products may show negative effects such as […]

This study proposes an extension of the pseudo-elastic cavitation model in order to describe the structural behaviour of silicone adhesives under cyclic loading. Based on cyclic uniaxial tensile tests as well as cyclic heavily constrained tensile tests, that is the pancake test, the material softening due to cyclic loading is described by the approach of […]

The building industry, where safety related joints are increasingly connected by adhesion technology, demand new quality assurance measures. Therefore, an appropriate monitoring technique for critical stresses and cracks in adhesive joints is essential. In this presentation, a new approach for in situ monitoring of transparent adhesives will be described. Microcapsules, filled with dyes or other […]

The Griffith theory describes the behavior of brittle materials. For the description of a crack creation, an energy equilibrium is used. At annealed glasses this equilibrium is reduced to a simple formula containing the mechanical energy in the glass and the surface energy needed for crack creation. The paper deals with the question, whether ball […]

The increase use of glass from window infill panels to structural glass urged engineers to characterized the mechanical properties of glass, especially the load resistance of glass, precisely. The load resistance of a glass decreases due to the presence of flaws, that acts as stress concentrators and propagation of unstable flaws leads to fracture. Flaws […]

During a recent project to understand the ability to use Transparent Structural Silicone Adhesive (TSSA) via linear bonding for cable wall fittings, a unique aspect of the material indicates a potential novel method for cold bending glass. Used in long sections and small widths, the TSSA was able to effectively bend and hold shape after […]

Optically tunable dynamic windows demonstrate many advantages over static lighting controls, such as blinds and shades. This technology allows users to control both heat and light flow into and out of buildings, without sacrificing their comfort or view. Dynamic windows based on reversible metal electrodeposition (RME) offer an exciting alternative to traditional electrochromic technologies. The […]

The thermal Transmittance of a curtain wall fenestration is the primary determinant factor driving the overall building envelope performance of a building to balance with its design aesthetical quality. Research has been performed to establish the merit of comparing digital FEM (finite element method) against the results obtain from experimental evaluation analysis. Thermal modeling technic […]

In the post-breakage phase, laminated glass (LG) can maintain a residual load-bearing capacity due to the tension stiffening of the polymer through the adhesion with the shards, but the determination of the overall post-breakage stiffness presents formidable difficulties. A simple model is here proposed for the in-plane response of broken thermally treated LG, characterized by […]

Within this paper the mathematical foundation, deduction, calibration and application of a Machine Learning inspired simulation approach for the prediction of fracture patterns of thermally pre-stressed glass via tessellations over stochastic point processes is shown. The method is called ‘BREAK'(Bayesian Reconstruction and Prediction of Glass Breakage Patterns) and allows the fast simulation of glass fracture […]

Laminated glass is used worldwide in buildings for its ability to break safely and to prevent the penetration of an impacting object. These abilities are described by standards, such as EN356 for resistance against manual attack or so-called “anti-vandal” glazing products. One of the test is the hard body drop test, where three steel balls […]

The structural sealant glazing (SSG) system was adopted in numerous skyscrapers glass facades since the mid 1980’s in Japan. The SSG facade continues being specified and built due to the proven performance of the past 30 years, through typhoon wind events, annual thermal and humidity cycles and seismic events. This paper reports the SSG performance […]

Silicone sealants have been applied for more than 40 years to structurally bond glass onto steel or aluminum frames. One of the reasons is the unique resistance to weathering in normal assembly situations. With vertically installed facades, there can be installation assemblies with horizontal silicone joints, on which standing water cannot be avoided. Despite the […]

Adhesive bonding is an efficient joining process with a great potential for material-efficient constructions. Today, the technology is already applied in almost all branches of industry. However, the building industry still has enormous catching up to do when it comes to load-bearing adhesive joints. The glass and façade sector provides an ideal field of application […]

The use of load-bearing adhesive joints in the glass structures have been in the focus of research throughout the last years. Due to design aspects, the transparent adhesives are of particular interest. This article – based on a concluded PhD-theses – focuses on the group of two-component epoxy adhesive. These group of adhesives have hardly […]
