East Area Branch Library
Denver, Colorado

Redevelopment of Stapleton International Airport and Lowry Air Force Base includes growing residential areas. When the city of Denver needed a new branch library to serve area residents, ample tax revenues were available to purchase a piece of architectural art instead of a more utilitarian structure. Michael Brendle Architects designed an unorthodox modern building and retained JFSA to design the hidden support structure. The metal and glass building is a conglomeration of geometrical units that requires special support for itself, its books, and the snow and wind loads every structure must contend with.

The new library building is a 15,000-square-foot steel-framed structure with two stories and a partial basement. The myriad of unique architectural and structural elements includes walls that are not plumb or square, and lean outward several feet over entryways. Where exposed, the structural steel elements frame together with seamless connections. Numerous roof levels and two-way slopes are incorporated in the design. A glass-walled conference room is suspended above part of the first floor. And large windows and tall storefronts on all sides of the building require special framing solutions and hidden lateral bracing.

JFSA used three-dimensional modeling techniques and worked closely with the architect to ensure accurate dimensioning and prevent component interference. Finite element analysis was employed to design lateral force resisting trusses. Unique details create seamless joints while allowing for construction tolerances.

This complex design was completed within budget and schedule constraints typical for an orthodox, rectangular structure.
