Evaluation of multiple column curves using the experimental data-base approach

The paper describes an extensive survey of column tests and an evaluation of information on steel column strength. During the past twenty-five years numerous series of column tests have been conducted in European countries, North America and Japan. A total of 1665 individual test results which have been stored in an experimental data-base is retrieved and a statistical appraisal carried out to evaluate experimental column strength. Comparisons are made between the surveyed test data and the ECCS and SSRC multiple column curves. The authors also propose new multiple column formulae which explain more accurately the test data from a statistical viewpoint.
