Title: Time-Dependent Load Transfer in Reinforced Lightweight Concrete Columns
Author(s): Thomas A. Holm and Joseph Pistrang
Publication: Journal Proceedings
Appears on pages(s): 1231-1246
Keywords: aggregate, column, creep, lightweight aggregate, lightweight concrete, reinfoced concrete, research, shrinkage.
Abstract:Time-dependent strains of an axially loaded, structural size, reinforced lightweight concrete column were observed for 1 year to verify a theoretical method of predicting the load transfer from concrete to reinforcing steel caused by creep and shrinkage. The method, which modifies "classical" equations by considering the interaction between creep and shrinkage, was verified within engineering tolerances. It provides an adequate means of predicting long term column deformations and load transfer using, as a basis, creep and shrinkage data from plain concrete cylinders.
