AD 252: Axially Loaded Columns – Base Plate Design Effective Area Method BS 5950-1:2000
The empirical method for determining the size of base plates in BS 5950-1: 1990 has been replaced by the effective area method in BS 5950-1: 2000. Doubt has been raised as to the theoretical validity of the empirical method when used with deep UB’s or with bases that have very small outstand dimensions a and b. The effective area method offers more economy than the empirical method, while still producing safe designs when compared to test results.
