Thermo-mechanical numerical analyses in support of fire endurance assessment of ordinary soda-lime structural glass elements

Purpose: Glass material is largely used for load-bearing components in buildings. For this reason, standardized calculation methods can be used in support of safe structural design in common loading and boundary conditions. Differing from earlier literature efforts, the present study elaborates on the load-bearing capacity, failure time and...

Exploratory Study on the Load-Bearing Behaviour of Laminated Glass Beams Exposed to Fire

All-glass structures have become increasingly popular with architects and builders in recent years. Glass surfaces are becoming larger and more impressive, while connections are being decreased to obtain maximum transparency. The supporting structure of glass facades, glass roofs or walk-on glazing is mostly made of metal. One of the reasons for...

The influence of fracture pattern on the residual resistance of laminated glass at high strain-rates: an experimental investigation of the post-fracture bending moment capacity based on time-temperature mapping of interlayer yield stress

Laminated glass panels are increasingly installed in glazed façades to enhance the blast protection of buildings. These ductile panels offer residual bending resistance following the fracture of the glass layers, due to the composite action of the attached glass fragments in compression and the interlayer in tension. Three-point bending tests...

Structural performance of a novel liquid-laminated embedded connection for glass

Connections between load-bearing glass components play a major role in terms of the structural integrity and aesthetics of glass applications. Recently, a new type of adhesive connection, known as embedded laminated glass connections, has been developed where a metallic insert is embedded within a laminated glass unit by means of transparent...

High strain-rate effects from blast loads on laminated glass: An experimental investigation of the post-fracture bending moment capacity based on time–temperature mapping of interlayer yield stress

To enhance the resilience of buildings, laminated glass panels are increasingly used in glazed façades. These ductile panels provide a superior blast resistance to that provided by monolithic glass panels, due to the improved residual capacity offered by the polymer interlayer following the fracture of the glass layers. The complex...

Effects of Humidity and the Presence of Moisture at the Bond-line on the Interfacial Separation of Laminated Glass for Flat Glass Re-use

The built environment is under scrutiny to address environmental design challenges by considering a whole-life holistic approach that seeks reductions in operational emissions whilst simultaneously pursuing reductions in embodied emissions. Reduced embodied emissions can be found through the responsible sourcing of resources and re-use of...

A structural concept for a demountable glass column: An explorative design study about interlocking, laminated glass components

The high compressive strength of the material glass in combination with its transparency, make it an attractive material to use for a column. Though different types and configurations of glass columns have been subject of academic research, a demountable glass column made from laminated components remains unexplored. This structural concept...

Structural Strength of Laminated Glass

The subject area "structural strength of materials" is defined generally as а complex of strength characteristics of materials and structural elements, obtained under special mechanical tests. It is shown that these tests should take into account not only the physical and mechanical properties of the material, but technology, blank processing,...

Glass columns: Structural analysis on replacing existing columns with glass

Not many glass columns exists in the world, and especially used for buildings. Safety and mass manufacturing is a problem. How can you make sure that a glass column is safe even enough for the public and in what way can it been manufactured? These are two of the seven problems I am faced with during my research. The purpose of this thesis is to...

Experimental and numerical analysis of thick embedded laminated glass connections

Laminated glass components are usually realized by bonding glass plates using interlayer polymers that develop adhesion forces during lamination. Recently, these adhesion forces have been used also to realize special adhesive connections for structural glass components and assemblies. The typical example of such a joining technique is...

Blast response of Glass Facades: Retrofit for blast effect mitigation in the event of a terrorist bombing attack

The number of terrorist attacks on public places has substantially grown over the past two decades. More than half of these attacks were bombings. Past bombing events have shown that 45% of the injuries is caused by glass breakage. . The building engineering practice could help reducing the consequences, by retrofitting glass facades to mitigate...

Finite-Element Numerical Simulation of the Bending Performance of Post-Tensioned Structural Glass Beams with Adhesively Bonded CFRP Tendons

In this paper, a Finite-Element (FE) numerical investigation is carried out on laminated glass beams with Carbon Fibre Reinforced Polymer (CFRP) adhesively bonded post-tensioning tendons. Taking advantage of past four-point bending experimental test results available in literature, a refined full 3D FE numerical model is calibrated and validated...

Assessment of the energy savings and CO2 emissions reduction of glass structures through alternative demolition scenarios

Glass is a material that has been significantly increasing its role in architecture in recent decades. Although glass is a material that can survive long, as can be seen from the archaeological pieces in many museums, in practice the glass structures that built nowadays have a finite life time. A notorious case is the original New York Apple...
