Beam and column systems require connection details that are coordinated, repeatable, and practical to produce and install. Whether the structure includes inverted tee beams, columns, spandrels, double tees, walls, stairs, risers, or grade-level precast components, connection hardware must support the intended load path while fitting the realities of plant production and field erection.
The Universal Precast Connector (UPC) gives engineers and precasters a standardized option for many common precast-to-precast connection conditions.
Beam and column projects often repeat the same connection conditions across a structure. Custom-fabricated plates can increase detailing time, fabrication cost, inventory complexity, and the risk of variation.
The Universal Precast Connector helps standardize applicable precast-to-precast details with one engineered embed. Fabricated from a single piece of steel, UPC can replace a range of custom-fabricated plate assemblies while helping producers reduce hardware inventory and fabrication costs.
UPC is designed for a wide range of structural precast interface conditions. Common applications include:
Structural precast connections often need to account for more than one load direction. UPC has been tested under monotonic tension, monotonic horizontal shear, and monotonic vertical shear, giving engineers a tested connection platform for applicable beam, column, spandrel, wall, and double tee conditions.
For each project, connection design should be completed by the precast specialty engineer or engineer of record using the appropriate published capacities, member geometry, weld details, and project-specific load requirements.
UPC is designed to support both the engineering detail and the production process. Its single-piece design can reduce custom fabrication, simplify stocking, and help producers focus on precast production rather than one-off metalwork.
In production, UPC is typically installed with at least one side exposed to a form face so it can be fastened during the pour. The connector legs should be tied and/or nested to reinforcement in the host member, with adequate concrete cover and final placement checks completed before casting.
UPC is a versatile connector, but each condition must still be designed and detailed for the specific project. Connection drawings should show the correct UPC orientation, host member placement, erection hardware, weld size, weld length, and joint width requirements.
Final connection design should be completed by the appropriate licensed engineer. MKA technical support can assist with product selection, application questions, and coordination support.
Universal Precast Connector (UPC) is the primary product for applicable beam, column, spandrel, wall, double tee, grade spandrel, stair, and riser interface conditions.
Original Ming Wing is relevant where the structure includes double tee diaphragm or flange connection conditions.
Ming Wing mini is relevant where the structure includes 2-inch double tee flanges, field-topped double tees, or thin-member conditions.
Drill and Bolt Connection is relevant where wall panels or grade-related precast components require a bolted base connection to a foundation.

For beam and column applications, the Universal Precast Connector (UPC) is typically the best choice. It is designed for precast-to-precast connections and can be used with double tees, inverted tee beams, spandrels, wall panels, and other structural precast applications.
Typical UPC applications include IT beam-to-column, double tee-to-load-bearing spandrel, double tee-to-IT beam, double tee-to-wall, grade spandrel-to-foundation, and stairs/risers-to-walls.
Yes. UPC connection details should be developed for each specific condition, including orientation, placement, erection hardware, weld requirements, and joint width considerations.
