Cold Bent Glass Sheets in Façade Structures

Cold bending of vertical glass plates: Wind loads and geometrical instabilities

“…Geometrical instabilities can indeed occur during the warping of the glass sheet. Such phenomenon was firstly reported by Staaks and Eekhout [18][19][20][21], who considered square plates fixed at three corners, while the fourth corner was forced out-of-plane. This load condition results in a hyperparaboloid form of the plate, where both diagonals are curved, and the edges remain straight.…”

Experimental Study on Single Corner Cold Bending Mechanical Response of Laminated of PVB Interlayer Tempered Glass Panes and the Coupling Effect with Load

“…Since the direction of the main tensile stress generated by cold bending was different from that generated by the load, the principal tensile stress obtained by uniformly distributed load test and the principal tensile stress generated by cold bending test are transformed into the same coordinate system for superposition. The coordinate transformation method of stress is shown in Equations ( 4)- (6). θ is the included Angle between Ox axis in the maximum principal stress coordinate system Oxy of uniformly distributed load test and Ox axis in the maximum principal stress coordinate system Ox y of cold bending test.…”

“…Due to its significant advantages, the cold bending method has been applied in large urban landscape public buildings such as museums, airport terminal buildings and exhibition centers in recent years. There are representative buildings, such as the Shining Towers in Abu Dhabi [2], the Credit Libanais bank in Lebanon [3], the Seele Glass Bridge in Germany [4], the Strasbourg Railway Station in Alsace, France [5], the new roof structure of the Amsterdam bus station [6], the Wujiang Shengze International Convention and Exhibition Center in China, a project in Shanghai Hongqiao [7], and Suzhou Central Plaza [8]. Especially for the new terminal building at Nanning Wuxu International Airport, the hyperbolic glass curtain wall designed by the cold bending method has a good effect, saving the cost, shortening the construction and achieving significant economic benefits.…”

“…Although some researchers have performed relevant research work [4][5][6][10][11][12][13]16], it is still in the initial stage overall. There are a few types of glass studies, which are limited to single glass [4,13,16] and a small amount of laminated glass [5,11,12,16].…”

Bridging the gap between rectifying developables and tangent developables: a family of developable surfaces associated with a space curve

“…Since any curved developable surface can be formed from a flat region while preserving the distance along any curve between any pair of points, the work required to deform thin sheets of materials as diverse as paper, leather, metal, and glass into developable shapes is much less than that needed to attain other shapes. Developable surfaces have thus been of longstanding relevance in many areas, including the design of ship hulls [2] and automobile parts [3,4], buildings [5,6], especially lightweight structures like facades [7] and pavilions [8], apparel [9] and footwear [10]. Due to the widespread utility of developable surfaces, methods for generating and processing them are now standard features of most computer-aided design platforms.…”
