چکیده
This study investigates the performance of monolithic and newly proposed dry beam-column joints using GFRP bolts, reinforcements, different types fibres subjected to pendulum impact. Six specimens were cast tested with increasing impact velocity until failure. The experimental results have shown that concrete joint reinforced bars showed better behaviour in terms energy dissipation (up 51%), reduced damage level, maximum residual displacement as compared reinforcements. test suggested steel bolts reinforcements could be effectively replaced by mitigate corrosion problem while still satisfy design requirements for both strength ductility. Furthermore, use (StFs) demonstrated impressive critical indices such level at high energies, synthetic (SyFs). Meanwhile, application SyFs led greater than StFs (between 6 30%). potentially applied practice reduce construction costs damaged/deteriorated components would easily replaced.

The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...

متن کاملPerformance of Corrosion-Damaged HSC Beams Strengthened with GFRP Laminates
This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A ...
