Tensioned fabric shape-finding

Tensioned glass fiber-reinforced fabric has been used in roofs and canopies for various permanent structures such as stadiums and airport terminals all around the world. At its final state of geometry, the fabric shall be all in tension in its natural stable shape. The natural shape of the fabric can be generated by refining a 2D computer model to determine the 3D state using a geometric nonlinear analysis program for the personal computer. This paper presents an actual design case using a general purpose structural analysis program to reduce the complexity involved in finding the true natural shape of the tensioned fabric roofs.


Analysis of structural glazing systems
Vallabhan, CVG; Aşık, Mehmet Zülfü; Kandil, K (1997-10-01)
Exterior glazing has been popular in commercial buildings especially in multistory buildings; the glass panels are bonded to the exterior of the building by silicone sealants. Thus, the glazing is identified as ''structural glazing''. Of all the structural glazing systems, the four sided support system is the most critical one. As the glass panels are designed to withstand lateral wind pressures, and when the lateral deflection of the panels increases more than its thickness, the glass plates behave nonline...
Structural fire safety of standart circular railroad tunnels under different soil conditions
Böncü, Altan; Caner, Alp; Department of Civil Engineering (2008)
In many tunnel designs, reinforced concrete tunnel lining design is selected based on construction requirements rather than design loads. A constant cross-section is typically used along a tunnel even if the design loads change from one location to another, especially for tunnels constructed by tunnel boring machines (TBM). Factor of safety against failure is not constant along the length of tunnel and is typically high at shallow depth regions. Factor of safety during a rare event is usually much less than...
Performance of perforated breakwaters constructed with geotextile tubes
Yalçıner, Ahmet Cevdet; Ergin, Ayşen (2006-12-01)
The coastal defense structures are constructed by various types of structural systems varying from traditional rubble mound types and concrete systems to more innovative systems. In recent applications the geotextile is used in some applications of coastal engineering a such as coastal erosion control or perforated breakwaters. The tubular concrete units can be prepared at site by using geotextile as formwork and construct a perforated structure by placing the tubes in a specified angle and spacing. The per...
Vertical Seawall Crest Modifications for Overtopping
Kısacık, Doğan; Özyurt Tarakcıoğlu, Gülizar; Baykal, Cüneyt; Kaboğlu, Gökhan (2018-08-03)
Crest modifications such as a storm wall, parapet or a bullnose are widely used to reduce the wave overtopping over coastal structures where spatial and visual demands restrict the crest heights, especially in urban areas. Although reduction factors of these modifications have been studied for sloped structures in EurOtop Manual (2016), there is limited information regarding the vertical structures. This paper presents the experimental set-up and first results of wave overtopping tests for a vertical wall w...
Seismic retrofit of buildings with backbone dampers
Shaban, Nefize; Ozdemir, Seda; Caner, Alp; Akyüz, Uğurhan (2017-01-01)
Dampers have been effectively used in new designs and seismic retrofit of old structures in many parts of the world. The common seismic retrofit practice in Turkey is almost purely based on stiffening the structure with additional shear walls or adding braces to limit the excessive seismic drifts. Such an approach usually results in expensive interior works and enlargements of foundations. The stiffening of the structure typically results in attracting more seismic force. Utilization of dampers as seismic p...
