AN APPROACH TO ESTIMATING LONG-TERM MULTIAXIAL CREEP BEHAVIOR FROM SHORT-TERM UNIAXIAL CREEP RESULTS

摘要

This report describes an experimental investigation of the creep behavior of concrete subjected to (1) multiracial stresses ranging from 0 to 3600 psi, (2) two different temperatures during loading (75 F and 150° F), and (3) two different curing histories (sealed and air-dried) and suggests predictive equations for estimating creep strains in the principal directions for stresses less than the creep proportional limit.
