Structures and Strategies for Transparency of Facade

The pursuit of transparency has been a primary driver of structural glass façade technology from its inception. Deriving from this pursuit is intent to dematerialize the Structural Glazing Systems in Pune supporting the facades. The primary strategy in achieving this dematerialization in volves the use of tension elements. Interestingly, this is consistent with a strategy of efficiency and sustainability; doing more with less material.

The following steps were initially recommended as a means to improve the economical efficiency of a truss, a technique here suggested for application to truss systems and the pursuit of transparency:

  • Minimize the length of compression members.
  • Minimize the number of compression members, even if the number of tension members must be increased.
  • Increase the depth of the truss as much as is practical to reduce the axial forces.
  • Explore the possibility of using more than one material in the truss, one for compression and another for tension.

A structural system designed such that certain elements receive only axial tension forces allows those elements to be significantly reduced in section area from elements designed to accommodate compression loads. A 100 millimeter diameter tube or pipe element can potentially become a 10mm rod or smaller, significantly reducing the element profile. The primary reason for this is that buckling disappears as a phenomenon. Small sections, 61 especially of high modulus materials, are remarkably strong in tension; thus the effectiveness of steel cable. The overall aesthetic affect can be quite dramatic. The tensile elements themselves are most frequently comprised of strand or rod materials, often in stainless steel, although occasionally galvanized and/or painted mild steel materials are used.

End fittings can be quite sophisticated in design, intended to present a minimal profile and leave no exposed threads while still accommodating the requirements of assembly and tensioning. These are generally high tolerance machined components with a quality finish. High strength alloy steels can be used for rod materials to further reduce their profile. Cables are, as a rule, more economical than rods, sometimes dramatically so. Cables are capable of bending within a specified radius with no loss of structural capacity, and can thus be used as longer elements intermittently clamped but requiring only two end fittings. Bent rods are most often impractical, so rods must be provided as discrete linear elements of greater quantity, each requiring two end fittings.

The additional quantity of end fittings drives up both the fabrication and assembly costs in most applications. Nonetheless, this method is sometimes used as an aesthetic preference. Both cable and rod fittings are currently available from a number of suppliers providing a wide variety of system types and aesthetics
