Pier Cap Beam

Figure II-4. The actual pier cap beam cross section [Maday, 2002]. All dimensions are in mm, and the 1:20

scale is no longer correct.

Figure II-5. The simplified pier cap beam cross section [Maday, 2002].

The pier cap beam height is not constant, since the pier cap beam is tapered. Thus the

average pier cap beam height is used, which is calculated as follows:
