A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.
Architect Robert Perry, the author of the as-built vs. as-designed report, focuses exclusively on rainwater entry into the building envelope, and makes observations that appear to be at odds with the evidence. For example, he claims that "dry rot damage [in the collapsed balcony] had occurred along the top of the cantilever balcony deck joists".

A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
Deflection (f) in engineering. In structural engineering, deflection is the degree to which a part of a long structural element (such as beam) is deformed laterally (in the direction transverse to its longitudinal axis) under a load.
Suspended structures of the center column type utilize high-strength cable to suspend or support the floors. In some cases beams are cantilevered out from the concrete column at the center of the building. From the top of the center column, cables are used to support the roof system and the walls.
Cantilever design was a new architectural technique in stadium construction in 1894, and National League Park was the first to be constructed with it. The ballpark's cantilevered concrete supports eliminated the need for many of the support columns in the pavilion that had made for "obstructed view seating" in the original ballpark and other ...
The Lewis and Clark Bridge is a cantilever bridge that spans the Columbia River between Longview, Washington, and Rainier, Oregon. At the time of its completion, it had the longest cantilever span in the United States. [1] The bridge was opened on March 29, 1930, as a privately owned bridge named the Longview Bridge. The $5.8 million cost ...
