Abstract

As a sequel to the first large database created at Northwestern University in 1978, this paper presents a further enlargement of the database, comprising 621 creep tests and 490 shrinkage tests. This database significantly extends the 1993 RILEM database, which contains 518 creep tests and 426 shrinkage tests. This new, conveniently computerized database will make possible more realistic verification and calibration of creep prediction models for design, provided that a proper unbiased statistical technique, compensating for inevitable strong statistical bias in the distribution of data, is employed. The database can be downloaded freely from the Web site http://www.iti.northwestern.edu.
