Abstract

This study evaluates the flexural performance of reinforced concrete (RC) continuous beams with double beam system (DBS). The DBS method with high-rigidity drop panels in beam-column joints can be expected to decrease the actual span of RC beams. To investigate the effect of drop panels, a total of nine RC continuous beam specimens with various rigidity and length of drop panels is cast and tested under monotonic gravity loads. As a result of test, the specimens with drop panels presented superior flexural behavior and lower deflection under service load compared to those of the specimens without drop panels. Furthermore, the specimens with drop panels showed smaller crack width under service load than compared specimens.
