DESCRIPTION:Unlike more traditional structural materials such as steel and
  reinforced concrete\, glass failure is brittle and fast. One of the bigge
 st factors limiting the use of glass as a load-bearing element is the unpr
 edictability of failure. This means 'structural glass' is seen as a niche 
 material which only a few structural engineers will consider using.\n\nUpo
 n fracture of a structural glass element two things must be ensured: 1) gl
 ass fragments must be held in place to prevent injury to building occupant
 s\, and 2) any loads previously carried by the glass must be carried using
  an alternate route. Laminated glass provides a good solution to both of t
 hese. Glass fragments stick to the polymer interlayer after fracture and l
 oads can be carried by a combination of tensile stresses in the interlayer
  and compressive stresses in interlocking glass fragments. \n\nCurrently t
 here is no predictive method for determining the magnitude or duration of 
 the 'post-fracture' load bearing capacity. In response to this\, this rese
 arch project focuses on determining a simple method of estimating the post
 -fracture load bearing characteristics of laminated glass.
