Bearing Pad Durability in Precast Concrete Garages

garage_File Opener

Bearing pads are used widely in precast concrete parking garages. They function as buffers between the separate concrete members to prevent damage and facilitate movement (much like cartilage between bones at joints). Bearing pads should last for the design life of the structure, but need to be replaced when they are not sufficiently durable. The ‘surgery’ to replace the pads properly is a complex operation, with few published guidelines.

By Dirk McClure

The University of Missouri, located in Kansas City, boasts the country’s first terra cotta-clad insulated composite precast concrete panels assembly.

Before this installation, terra cotta had been clad into non-insulated panels in a few projects. At the Henry W. Bloch Executive Hall for Entrepreneurship and Innovation, however, terra cotta tile was clad onto 1783 m2 (19,200 sf) of 3.6-m (12-ft) wide insulated composite precast concrete sandwich panels.

Ultra-high performance concrete (UHPC) provides strength, ductility, durability, and aesthetic design flexibility while still being highly moldable and able to replicate texture, form, and shape. It is this combination of superior properties that also provides architects and engineers with a new kind of freedom—to design unique, unprecedented UHPC architectural elements that are also sustainable and extremely durable.

G8WAY DC is a new open-air, multi-use facility that demonstrates that precast ultra-high performance concrete (UHPC) is a suitable material choice for challenging architectural elements that require attributes ranging from light weight and imperviousness to complex shapes. Providing shelter below and a large, landscaped seating area above, the pavilion’s sculpture-like UHPC roof transcends this utilitarian facility into an artistic statement.

Although it has long been associated with utilitarian projects like factories and big-box stores, tilt-up concrete construction also has the capacity up to deliver multi-story, irregularly shaped, complex projects. Examining recent award-winning projects provides examples of how architects have been embracing tilt-up in increasing intensity.
