Furthermore, the empirical models available in ACI From the obtained data, the time-dependent kt multiplier, accounting for crack width increase after one year, was deduced as 1.
Phase 4 deals with four full-scale GFRP reinforced concrete beams, of dimensions mm x mm x mmsubjected to uniform distributed load for a period of six months. Author s Youssef, Tarik A.
Satisfactory results were found when the k b bond-coefficient factor is taken as 1. The theoretical curves were in very good agreement with the measured values. The program, consisting of four phases, studies the creep performance of FRP bars as well as s8806-02 overall long-term behaviour of FRP reinforced concrete beams.
Phase 1 deals with the creep performance of two types of GFRP bars subjected to different levels of sustained axial load; causing creep rupture at higher levels. These predictions showed that both models can serve as upper bound and lower bound cs for the measured long-term deflection curves, respectively.

Some features of this site may not work without it. Microstructural analysis shows that the increase in creep strain, after the hour period, is negligible for GFRP bars under allowable service load.
Show full document record. Residual tensile tests and microstructural analysis followed the long-term testing period. Immediate crack width results were compared to s806–02 prediction equations adopted by ACI Theoretical predictions for immediate deflection were calculated, using three methods ACI As regards crack width prediction, the equations adopted by ACI Results showed that the North American standards are conservative as regards long-term deflection prediction.
For both equations the time-dependent kt multiplier is deduced as 1. The long-term to immediate deflection ratio. Numerical modelling took place using a computer program Fortran based on the age-adjusted effective modulus method, to predict the long-term deflection of the beams.
The dimensions of which s806-022 mm x mm x mm, installed under third-point sustained load, for a period exceeding one year.
