Simpson Strong-Tie Concealed Connectors for Mass Timber Glulam Columns

Simpson Strong-Tie has introduced three new connectors for mass timber glulam columns.

Simpson Strong-Tie has introduced three new connections for mass timber glulam columns, the MCT for column-to-column installations and the MCB and MCBS for column-to-foundation installations. Each offers a concealed connection for architectural aesthetics and fire protection. 

The MCT mass timber column tie connects two columns together while allowing the vertical download to be transferred by column-to-column bearing. Its universal design allows the same connector to be used on a wide range of column sizes and is compatible with the Simpson Strong-Tie line of concealed beam hangers.

Comparatively, the MCB and MCBS mass timber column bases provide standardized connections between glulam columns and concrete foundations or supports. The MCB is the economical option for use in conditions where a standoff between the column and the concrete is not required. Conversely, the MCBS provides the highest download capacity for a given column size and can be used where a standoff is required.
