چکیده
A popular water pipe system, used in many countries, is one formed by prestressed cylindrical concrete pipes (PCCP). This study the results of an experimental investigation on ten (10) PCCP samples taken from existing pipeline. The objective was to investigate their bearing capacity under three-edge bending or internal hydraulic pressure loads check capability specific retrofitting/strengthening schemes upgrade this and thus enhance operational period (Part A). In part B study, measured response made validate a numerical approach aimed at numerically simulating behavior original retrofitted pressure. From obtained results, it seen that assumed nonlinear mechanisms for volume steel membrane were verified comparing predictions with measurements terms strain membrane, damage patterns volume, overall versus radial expansion response. contribution fully active prestress as well three jacketing schemes, including carbon fiber reinforced polymer (CFRP) (RC) jackets, also comparisons corresponding

متن کاملBehavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets
In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...
