Grand Entry Wall, Salt Lake City Library

The so-called “lens” wall of the Salt Lake City Library wraps the southeastern façade of the building, facing the Wasatch Mountains. The glass support structure was designed to minimize visual impact using components optimized for the client’s budget.

TriPyramid worked with the design team of architects and structural engineers to develop the tension truss system and integrate it in the steel mullion design (mullions manufactured by others). TriPyramid supplied the A586 galvanized strand cables with B315 end fittings and produced intricate strut fittings which clamp to both the vertical and horizontal cables, and are used for tensioning. TriPyramid also developed a system of small, vertical rods from our A22 medium strength line to support the horizontal mullions against the deadweight of the glass panels.
