A Glass Pavilion

T. Herrmann & S. Siebert
In January 2015 a pavilion mainly built of glass was finished. The building contractors themselves planned it as a transparent extension of their detached house to the garden. The structural system consists on one hand of a glazed steel frame with four stanchions rigidly fixed to the base plate and connected by four transoms at the top and on the other hand of two laterally glass attachments. These are made of vertical load-bearing glass walls...

Fracture Resistance, Surface Defects and Structural Strength of Glass

Yurii Rodichev & Frederic Veer
This paper poses the theory that the fracture resistance of basic float glass is dependent on it physicochemical properties and the surface defects formed under the float glass production, glass processing and handling at the service conditions compose the aggregate basis for structural glass strength assessment. The effect of loading conditions, constructional and technological factors on the engineering strength of glass can be evaluated in certain cases using fracture mechanics with information on the initial...

Assessment and Management of Strength and Durability of Composite Glass Elements

Yurii Rodichev
The composite load bearing glass elements have the many advantages as compared with the massive glass structures [1, 2]. The use of high strength, plasticity or viscous behavior of the additional structural elements increases the safety and strength of glass composite. However, the main peculiarities of glass composite mechanical deforming, strength and fracture are remain induced by the primary influence of elastic and brittle nature of glass components on the whole composite structural behavior [1]....

Fragmentation of Heat-Strengthened Glass: Implications for Glass Not Conforming to ASTM C1048

Mark K. Schmidt
Heat-strengthened glass with residual surface compressive stresses above those allowed by ASTM C1048 was installed in a curtain wall in the mid-Atlantic region of the United States. To address building ownership’s concerns regarding postbreakage glass fallout, fragmentation tests were performed using a protocol adapted from EN 1863. Consistent with previous research, no significant difference in fragmentation was noted between samples with residual surface compressive stresses conforming to ASTM C1048 and those with residual surface compressive...

Mechanical Modelling of In-Plane Loaded Glass Panes

Paulo J.S. Cruz, José Pequeno, Jean-Paul Lebet & Danijel Mocibob
Glass panes are increasingly being used to the stabilization of one storey buildings by acting as shear walls and thus replacing conventional bracings. This is the case of glass pavilions and some timber or steel frames or facades. The behaviour of such structural systems mainly depends on the stiffness of the connections. This research focuses on the prediction of the in-plane structural behaviour of steel and timber frames with a single pane fixed by circumferentially...

Influence of Temperature on Post-Breakage Behaviour of Laminated Glass Beams : Experimental Approach

D. Delincé, D. Callewaert, J. Belis, R. Van Impe, F. Galmart & N. Matthijs
The assessment of the post-breakage performances of laminated glass elements used in construction need to take into account the sensitivity to the temperature of the mechanical behaviour and properties of the product, in particular of the interlayer material. A general problem statement and an overview of different experimental approaches are firstly presented. Then results of specific orientation tests on pre-cracked laminated glass beams with a stiff interlayer of DuPont carried at three different temperatures (23,...

Structural Glass Observation Boxes (Willis Tower Ledge)

T. McDonnell & D. Thompson
The 1,350 foot high Willis Tower (formerly known as Sears Tower) was looking for a grand attraction for their Skydeck in 2008. Few structures in the world have glass floors (both interior and exterior), and almost all are continuously supported along their edges with steel supports. In order to create a dramatic, unimpeded view of the City of Chicago the Skydeck Owners conceived of a glass platform that would protrude out of the building envelope...

All Transparent Conservation Scheme for the Menokin Ruins

E. Lowe
The challenge of preserving the 18th century ruin at Menokin, Virginia USA, has inspired a radical scheme to authentically conserve the surviving architecture. The ruined building is in a state of decay and Dewhurst Macfarlane & Partners have designed a glass structure to re-establish the protection of the building envelope. The plans presented are not ready for construction. Details for splicing together timber and glass beams are discussed. The conservators plans to recreate the missing...

TKTS – Tilted Glass Bearing Walls and Glass Roof

M. Ludvik & A. Smith
The TKTS booth in Times Square, New York, is a 250m2 all glass public amphitheater, with seating for 500 people. Its all glass load path includes treads, rafters and the 4.9m tall SentryGlas laminated walls. The 9.1m long beams were spliced using the overlap method with pins. The glass walls hold the full weight of the structure above, and in the real world environment of Times Square there are many possible causes of sudden failure...

Opportunistic Glass

M. Simmons
The proliferation of glass elements in building assemblies yields an endless array of fabricated components that are by nature glass-composites, resultants of myriad material techniques and processes. Every component parameter is an opportunity for detailed material definition in the service of a specific Architecture. Front designs and deploys glass technologies through creative and pragmatic collaboration seeking with our partners to opportunistically engage such materials in appropriate and specific ways so as to realize a broad...

Merging Two Façade Types into a New Product: Glass Sandwich Panel

M. Teich
Developed by seele for industrial and commercial buildings, iconic skin glass sandwich panel (GSP) is a novel glass panel façade that meets high-level design and economic demands. The idea is to merge two established façade products into a new one: The glass sandwich panel consists of an outer printed glass sheet bonded to a standard sandwich panel. This creates a glass exterior in the form of panels up to a height of 15 m. These...

Experimental Investigation on Post-tensioned Spannglass Beams during Temperature Loads

M. Engelmann, P. Bukieda & B. Weller
Recent research work focused on material efficient and safe structural use of glass beams. Reinforcing and post-tensioning of those structures in the style of reinforced concrete are promising options. They allow for a safe post-breakage behaviour of load bearing glass constructions. Other ductile materials such as steel and high-grade cables strengthen the glass, which results in robust structures. However, hybrid structures are prone to temperature loads. Especially post-tensioned glass beams – Spannglass Beams – are...

Impact Performance of Thin Glass-Polycarbonate Composite Panels

M. Cervio, G. Muciaccia & G. Rosati
Safety glass is usually the proper designer choice when glazing may be subjected to the impact of a person. In order to avoid people injuries, glass products must comply with appropriate safety practices. Existing technical standards classify safety glass products by mode of breakage and post-breakage behavior. Critical demanding applications in terms of self-weight saving, like high efficiency elevator cars in buildings or aircrafts and other means of transportation interiors in aerospatial and automotive industries,...

Low Cost Double Curvature – Exploratory Computational Modelling, FE-analysis and Prototyping of Cold-Bent Glass

P.. Eversmann, A. Ihde & C. Louter
The fabrication of projects with complex geometries often implies a significant waste of material, since custom molds need to be created and irregular shapes need to be cut out of larger sized elements. For low curvatures, cold elastic bending processes can be applied. However, elastic bending techniques have mainly been utilized to create simple curvature panels for architectural projects. This paper explores computational simulation in relation to a digitally controlled fabrication method of bending rectangular...

Laser Tracking Metrology: An Integrated Fabrication Process for Geometrically Complex Facade Systems

B. Rogers
The geometric complexity resulting from the architectural pursuit of freeform structures is presenting challenges to the construction industry. Curtain wall unit system designs, for example, have morphed in some cases from predominantly flat orthogonal affairs to complex double-curvature multi-layer constructs. Many fabrication tools and processes, however, are only gradually shifting from their linear 2D roots to embrace a truly 3D fabrication environment. The validation and quality assurance of geometrically complex components is problematic in such...

Kerstin Puller, Pascal Heinz, Björn Frettlöhr, Jürgen Denonville & Werner Sobek
During two semesters the ILEK (Institute for Lightweight Structures and Conceptual Design) held an explorative student workshop focusing on new glass design possibilities. Students from the faculties of Civil Engineering and Architecture first gained insight into the theoretical foundations of glass and different fabrication techniques, and then applied these techniques to realize a design theme of their choosing. The range of themes was intentionally left open and the scope of the techniques employed was correspondingly...

Structural Transparency – A New Wood Plastic Composite Girder

J.-D. Wörner & C. Eckhardt
Transparency is one of the significant features of modern architecture. By utilising transparent materials the feeling of lightness can be conveyed. This paper shows the possibility of employing transparent plastic as a load-bearing element. In order to be able to use a new material as part of the building structure it is essential to know its mechanical behaviour under various conditions like different temperatures, environmental impacts or the load duration. Proposals for the design of...

Glass-Steel Beams as Structural Members of Façades

B. Weller, A. Meier & T. Weimar
Glass used in structural applications enables a higher level of transparency in façades. However, attention should be paid to the material specific properties, such as brittleness and its incapability of plastic deformation. Laminated glass beams may improve several properties due to the elastic behaviour of the interlayer material. Contrary to laminated panes, which are subject to plate bending, laminated beams lose all their bearing capacity in case all individual plies are broken. The presented hybrid...
