|Title:||Statistics and size effect in cementitious materials||Authors:||Cotterell, B.
|Issue Date:||Feb-1995||Citation:||Cotterell, B.,Mai, Y.-W.,Lam, K.Y. (1995-02). Statistics and size effect in cementitious materials. Cement and Concrete Research 25 (2) : 408-416. ScholarBank@NUS Repository.||Abstract:||The statistical size effect in cementitious beams is examined using the assumption that the critical threshold stress to cause a strain-softened fracture process zone to be initiated follows the Weibull distribution. The fictitious crack line model and the K-superposition theory, in combination with the statistical strain-softening relationship, are used to determine the strength of plain and notched beams. For notched beams the statistical effect on the strength is only important for small beams, but causes a large variation in all sizes of plain beams. © 1995 Elsevier Science Ltd All rights reserved.||Source Title:||Cement and Concrete Research||URI:||http://scholarbank.nus.edu.sg/handle/10635/58727||ISSN:||00088846|
