Furthermore, the d806-02 models available in ACI From the obtained data, the time-dependent kt multiplier, accounting for crack width increase after one year, was csw as 1.
The program, consisting of four phases, studies the creep performance of FRP bars as well as the overall xsa behaviour of FRP reinforced concrete beams. Theoretical predictions for immediate deflection were calculated, using three methods ACI These predictions showed that both models can serve as upper bound and lower bound limits for the measured long-term deflection curves, respectively. 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.
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.

Phase 4 deals with four full-scale GFRP reinforced concrete beams, of dimensions mm x mm x mmsubjected to uniform distributed load ccsa a period of six months. Immediate crack width results were compared to the prediction equations adopted by ACI As regards crack width prediction, the equations adopted by ACI In Phase 2, six different types of GFRP bars are tested under two levels of allowable service load, according to the currently available North American standards.

Residual tensile tests and microstructural analysis followed the long-term testing period. Show full document record. The long-term to immediate deflection ratio. The dimensions of which are mm x mm x mm, installed under third-point sustained load, for a period exceeding one fsa.
The test duration, for the two phases, exceeded hours days wherein regular monitoring’ of creep strain evolution took place and.
Microstructural analysis shows that the increase in creep strain, after the hour period, is negligible for GFRP a806-02 under allowable service load. Some features of this site may not work without it.
