Roof Steel Truss Supported on Masonry Wall with Concrete Chainage Beam
This is a CAD dwg drawing for a Roof Steel Truss Supported on Masonry Wall with Concrete Chainage Beam. Steel truss is consisted of SHS profile members. Bottom truss chord is connected with a moment resisting baseplate detail on top of reinforced concrete chainage tie beam.
Connection is achieved with a reinforced concrete chainage beam ( tie beam or link beam ) on top of the masonry wall. Masonry wall is a load bearing wall either with stone or bricks and acts as a structural member for the structure. The chainage beam acts as a good bondage member between the steel beam ( anchorage bolts ) and the masonry wall as well as gives stability and ties together the load bearing wall. Chainage beam is actually a ring bond beam running throughout the length of the masonry wall. It is derived from the french word chaînage .
Steel truss is anchored down to the concrete chainage beam with a welded baseplate using anchorage bolts on both sides of the bottom chord. Stiffener plates are also used on both sides of the bottom chord.
Very useful detail when designing for existing buildings with steel frame additions / restorations.
