Explosion-proof glass facades. A way forward using silicone structural glazing
Structural silicone glazing is a technology that has proven its value in practice for more than 35 years. Structural silicone glazing is durable and secure even under extreme conditions such as heat, cold, tornadoes with extreme wind velocities, high humidity, acid rain and earthquakes. The first four-sided structural silicone glazing project in Detroit has functioned with the original structural glazing bonds since 1971. Structural glazing technology is able to meet the challenges of modern architecture while creating stronger and safer structures for future generations. The unique forces of a bomb explosion are characterized by an extremely high stress within an extremely brief period of time. Typical detonation conditions can lead to an impulse of up to 550 kPa/ msec and more. In the case of a very sudden impact or explosion, it is critical for a structural glazing adhesive to remain elastic and to maintain its adhesion to the substrate. Any glass-like properties (hardening) of the adhesive could in this case lead to cohesive failure. The BP Exploration Alaska Building in Anchorage, Alaska is a 16-storey project with four-sided SG fagades. The 1880 mm x 2133 mm large fagade elements were made in 1984 using a structural glazing adhesive that is designed for a maximum wind load of almost 2 kPa. In Anchorage, extreme temperatures from -37 deg C to + 29 deg C have been recorded. Since 1984, the building in Anchorage has withstood 12 earthquakes greater than 7 on the Richter scale.
