The Indianapolis downtown library features a unique design for the facades. The façade fits between two independent buildings. To create a transparent façade using cables, a novel counter-weight system was adopted. Horizontal cables are anchored to one building and run over a pulley to turn 90 degrees and a large hanging cast iron disc creates a constant cable tension. As the wind pressure hits the façade, the disc can move vertically. Corner clamped glass adds to the transparency.
Radhi Majmudar PE, Principal-In-Charge at DMP was responsible for the construction administration of the first glazed horizontal cable and corner clamped glass in the United States. Project is a highly unusual cable wall with a structural support system that consists of a ¾” pre-stressed stainless steel cable that is invisible behind a ¾” joint. Glass panels are attached to cables by stainless steel or spider fittings and horizontal cables are weighted at ends using level and counterweight. The design was completed in 2006 with a construction cost of $100 million.
