Office Building Built Using Cavity Connectors

During the design of the Watermark office building in Charlotte, NC, the structural consulting engineer was looking at various methods for connecting a beam to a tube column. Conventional methods such as through bolting or welding were considered, but quickly discarded due to the architectural nature of the project.

Therefore, the engineer looked to LNA Solutions for assistance:

Issues of concern were:

• Structural Integrity
• Aesthetics of the exposed steel
• Ease of Installation
• Labor Savings

After the engineer reviewed the load tables for a cavity connector, he selected and specified the 1/2” cavity connector for this project. Nearly 700 bolts were used in the construction of this office building. The cavity connectors were used to connect the beams with an end plate back into the tube column.
