Building system and method of construction

Abstract

A building system is disclosed comprising a beam and column connection particularly suited for mass timber buildings. A first connection arrangement comprises a projection and slot arrangement with the beam being supported on an upwardly facing bearing surface. A second connection arrangement may be provided to tie the column to the beam. The system also discloses arrangements to accommodate greater tolerance at the connection and to provide an ability to accommodate limited rotation under dynamic loading.
