Adaptive glass pane using shape-memory alloys

Abstract

Glass is one of the most commonly used building materials in modern architecture around the world. Its ability to pass through natural light enabled the builders paradigm of a desire for a exterior environment connected space, but yet comfortable and protected. New techniques and recent developments in fabrication processes made possible to use glass as a structural material. Structural glass propelled construction in glass, turning it into the most distinctive material of modern architecture. Because of the glass design complexity, glass as a construction material, however, still represents a challenge for structural design engineers. Glass is often associated to smart systems and active control researches, evolving shapememory alloys or pre-stressed cables. This dissertation's aim is to contribute to the development of a shape-memory alloys smart system, associated with a glass pane, in order to mitigate the wind action effects on the structure. The hazardous effect of the temperature on the interlayer of the laminated glass is also considered. The control action is imposed by an external system that causes an external force on the structure, enabling the system structural response to be improved.
