Steel roof beams

Existing wall

•Side view of the structural modal

Steel columns

This conceptual structural model (1:50) is to illustrate the structural system of the roof of ERC building, which can be divided into three parts. The first part is the existing wall which is made by concrete in the real structure, and there are steel made columns on the other side. This two parts is the structure to support the roof structure which is steel roof beams.

During the modal making process, our group found that the modal is moving if it only made by this three parts, thus we add this two beams( as showed in the circle) between the columns and roof beams to make it stable.


As for the shape of the columns, it has showed the wide-flange(W) shape steel, which is a sort of more efficient shape. It means that has less material cost, and using lightest steel section resist bending and shear force (Ching 2008, p.4.16).

As showed from the drawings, the connections of steel beams and existing concrete wall use end plate welded to beam all around and bolted or welded for the connection.
