The Lincoln Center for the Perfoming Arts is the most significant cultural centre in New York. The architectural firm Diller Scofidio+Renfro transformed the entire complex. They have designed two widely projecting glass awnings. Two steel columns, are piercing through a pedestrian ramp and establish the only support point for the 89 ft long structure. The elevation shows the two columns as a abstract Y. These two supports absorb all the horizontal loads of the structure and transfer them into the concrete slab of the pedestrian ramp. The two columns are connected by two frameless laminated glass sheets of 4 x 12 mm float glass. Two 89 ft long steel girders are resting on the two columns. While a circular tube, which is intersecting the steel girders, connects them to the building together with the pair of Y-columns. The two girders have a suspended glass plane. Each of them weighs 1.5t. They are suspended via point supports made of a high-tensile material, on four points only. Casted and actuated by adherence, using a two-component injection mortar, glass and steel form a statically effective connection. The inclination of the cantilevers, which are also not running parallel, and the inclination of the single glass panels necessitate every single point support to be a product made to specification.
