Paper Title:
Investigation of Experimental Model for Designing Concrete Bridge Deck Reinforced with GFRP Bars
  Abstract

Since the traditional design methods are based on the simply-supported experimental model, the bearing capacity of concrete bridge deck reinforced with GFRP bars is often determined by serviceability limits. The predicted bearing capacity is so low that high reinforcement ratio and construction cost are lead to. However, the previous researches on concrete bridge decks reinforced with GFRP bars revealed that crack widths and deflections were far less than the predictions by traditional codes, due to the existing of compression membrane action. This paper proposes a restraint test model to stimulate the comprehensive working property of deck system,considering the restraint from other part of the deck. Compared with simply-supported test model, bearing capacity and serviceability of the proposed are improved by more than 1 time. New experimental model for designing concrete bridge deck reinforced with GFRP bars are required.
