TESTINGS
Tested to Perform. Engineered to Last.
Vrecast panels are subjected to full-scale laboratory testing that simulates real service conditions. Testing of the panels was carried out under critical design loading and boundary conditions for performance assessment.
Flexural testing of the Vrecast panel specimens included loading applied from both the concrete face and the cold-formed steel backing face to represent critical in-service conditions. Two distinct test setups were used to evaluate panel flexural and composite behavior under the most demanding loading scenarios, capturing both global flexural response and composite interaction between system components. Flexural tests were conducted using a four-point bending configuration in accordance with ASTM E72 and Metal Stud pull-out tests were conducted to ensure reliable assessment of flexural strength, stiffness, composite behavior, deflection control, and overall structural performance for structural and architectural cladding applications.
Panel Flexural Testings
Metal Stud Pull-Out Tests
Pull-out testing was conducted to verify the anchorage performance and tensile capacity of connectors and embedded inserts used in the VREcast wall panel system. This testing program was intended to confirm that the connection assembly can safely resist out-of-plane tensile forces arising from wind pressures, seismic actions, handling stresses, and in-service loading conditions.
The test specimens consisted of GFRP bent bars in the concrete panel to an embedded depth of 1¼”. The anchorage capacity of the embedded GFRP composite tie bars was evaluated under direct pull-out loading. The GFRP bent bars were mechanically restrained using Vrecast proprietary connectors (VRE-Connectors), positioned between two cold-formed metal studs to replicate the as-installed field condition.
Tests were performed for evaluating the strength of GFRP anchorage in concrete. The test assembly rigidly restrained the metal stud framing while a controlled tensile load was applied normal to the panel surface through the connection system, inducing pull-out action to the embedded GFRP bent bars.
Load was increased incrementally until failure, and both applied load and connection response were monitored throughout the test. The pull-out test set up results indicated an ultimate anchorage capacity of 10 kips, demonstrating adequate tensile resistance of the GFRP bent bar and connector assembly for its intended structural cladding application.
