Analiza greda od samozbijajućeg betona ojačanih GFRP-om ; Analysis of GFRP-reinforced beams in enhanced SCC
U ovom istraživanju ispitano je ponašanje pri savijanju greda ojačanih staklenim vlaknima armiranim polimerom (eng. Glass Fiber Reinforced Polymer - GFRP) dvaju različitih omjera (0,68 % i 1,03 %) upotrebom tradicionalnog samozbijajućeg betona (eng. Self-Compacting Concrete - SCC) i SCC-a s 30 % ultrasitne troske (UFS). U istraživanju su analizirani uzorci pukotina, načini loma, odnosi opterećenje-progib, deformacije betona i armature te utjecaj omjera armature i tlačne čvrstoće SCC-a. Rezultati pokazuju da je premalo armature uzrokovalo pucanje polimera sa staklenim vlaknima, uravnotežena armatura dovela je do loma šipki i betona, a grede koje su sadržavale previše armature uglavnom su doživjele drobljenje betona u zoni stlačivanja. Ovo istraživanje usporedilo je ACI smjernice za projektiranje savijanja (2015.) s eksperimentalnim podacima. ; This study investigated the flexural behaviour of glass fibre-reinforced polymer (GFRP)-reinforced beams with two different ratios (0.68 % and 1.03 %) using traditional Self-Compacting Concrete (SCC) and SCC with 30 % Ultrafine Slag (UFS). The study analysed crack patterns, failure modes, load-deflection responses, strains in the concrete and reinforcement, and the influence of the reinforcement ratio and SCC compressive strength. The results indicated that under-reinforcement led to the rupture of the GFRP, balanced reinforcement resulted in bar and concrete failures, and over-reinforced beams mainly experienced compression zone concrete crushing. This study compared the ACI Flexural Design Guidelines (2015) with the experimental data.
