How Does the VERSA:T:™ Beam Work?

Similar to traditional composite design, the beam is designed for two conditions: non-composite, prior to concrete placement, and the composite beam final product. In the non-composite stage the VERSA:T:™ beam acts as a floor support system and stay-in-place form, providing an immediate working surface and fast assembly. Prior to achieving full composite strength development, shoring at 6 to 8 feet spacing is required to support the VERSA:T:™ beam.

After concrete placement and curing, the VERSA:T:™ beam final product exhibits the optimized material use characteristics of the fully-composite design. The VERSA:T:™ steel form now acts as much more than a stay-in-place form; it contributes to increased strength and increased stiffness of the composite VERSA:T:™ beam. Welded shear stud connectors are engineered and provided during the fabrication of the VERSA:T:™ beam to eliminate slip between the steel form and confined concrete and ensure full composite action is realized.

How Are the VERSA:T:™ Beam Materials Optimized?

Steel: Efficiently and cost-effectively provides required tension force resistance for VERSA:T:™ beam strength development. Enhances VERSA:T:™ beam stiffness allowing for smaller beam sections and lower floor profiles. Acts independently to provide floor support system allowing for immediate working surface and fast assembly.

Concrete: Efficiently and cost-effectively provides required compression force resistance for VERSA:T:™ beam strength development. Provides for the development of diaphragm action with the floor slab and building lateral force resisting system.
Non-flammable material and poor thermal conductivity characteristics are utilized to meet fire resistance requirements without the need for additional fire-proofing materials.

How does the VERSA:T:™ Beam Meet Fire-Resistance Rating Requirements?

Due to its poor thermal conductivity and non-flammable material components concrete provides the best fire-resistance of any common building material. The VERSA:T:™ beam utilizes the material characteristics of concrete to provide inherent fire-resistance in each beam. Our beam design process includes analysis based on AISC Design Guide 19: Fire Resistance of Structural Steel Framing and International Building Code, Chapter 7 Fire-Resistance-Rated Construction.

In the event of a fire it is assumed that the VERSA:T:™ steel form would reach temperatures high enough to significantly reduce the material strength of the steel. This is accounted for in our fire-resistance design procedure by neglecting the strength contribution of the steel form. The residual strength of the remaining concrete section is utilized to meet project specific fire-resistance rating requirements. This approach has been tested and verified in Underwriters Laboratories® testing consistent with the requirements of ASTM E119. As a result of the testing the VERSA:T:™ beam carries a 2-hour UL® fire assembly rating (UL K916).
