PRODUCT TESTING

Tested. Retested. Proven.

Testing is core to our product development. From working with leading contractors to study efficiencies in the field to strength and fire testing in the laboratories, we study every angle.

NC State Performance Testing

Overview Evaluate the structural performance of Diversakore® U-Beam as a primary supporting member within a conventional building floor system. Evaluate the influence of parameters such as bond between steel and concrete, amount of mild steel reinforcement, effect of positive or negative bending, and joint end condition. Validate shear bond interaction behavior collected from push-out tests with flexural response of full scale beam tests.

Key Outcome Composite beam has many design advantages.

Ga. Tech Flexural Testing

Overview This report presents the results of three full-scale tests on simply-supported beams designed as part of the development of the DiversaKore system. The specimens were instrumented for load, deflections, and strain measurements, and the results were analyzed and compared to theoretical predictions. The beams showed excellent flexural behavior, achieving their full nominal capacity before the tests were stopped. The predictions for the strength and stiffness of the beams based on simplified plastic models gave very good correlation to the results. In addition, a series of numerical studies using ABAQUS were carried out to predict the response of the assembly under ATSM El19 fire loadings. It appears that some mild steel reinforcement embedded at least 3 in. into the concrete will be needed to maintain a 2 hr. fire rating.
