Hollow laminated glass and its mechanical properties. Typically, laminated glass is used in store Windows, doors, and display cases. It has good sound absorption and insulation functions. In some cases, it can also be used in residential areas. However, it costs significantly more than other types of glass. It can be refitted into old or damaged frames. In some areas, it is more effective to use tempered glass. The difference between the two is that toughened glass breaks in a brittle manner, while laminated glass maintains its consistency when broken. In addition, toughened glass is easier to penetrate than laminated glass.
Hollow reinforced glass beams have been extensively studied. They can be safely used in statically indeterminate systems and exhibit high performance after fracture. They are also suitable for refitting, thus providing additional protection to the building. The film ensures that the glass does not shatter, and small, sharp pieces are fixed to the film in the middle. They are also resistant to penetration by deadly weapons.
The mechanical properties of SG sandwich depend on the duration and temperature of the load. Therefore, it is very important that the bond between the stiffener and the glass is well designed to achieve ductile failure behavior. When the bond fails, the final collapse mechanism changes, which may lead to brittle collapse of the beam. The strength of the glass beam can be enhanced by adding additional compression components to the top of the glass section.
To assess the effect of dimensional tolerances, a numerical model is generated and compared with experimental specimens. The model is then modified to reflect the measured results of the sample. This results in average measurements that are usually smaller than nominal values. In some cases, a simplified elastic method is used to determine the load behavior of the beam. These analyses are then verified by the average measurements of the test specimen.
Three - point bending test of double - sided reinforced laminated glass beam was carried out. The bending stiffness of a beam is compared with that of a single - sided beam. It is found that the single-sided beam has lower bending stiffness and lower initial failure load. This is attributed to a reduction in the moment of inertia of the mid-span glass section. It is also found that the addition of compressive reinforcement at the top of the beam increases its bending stiffness.
