The objective of this study was to investigate the seismic behavior of slender concrete diagonally-reinforced coupling beams (DRCBs) with an aspect ratio of 3.5 and to explore the possibility of alleviating the reinforcement detail for DRCBs using high-performance fiber-reinforced cement composites (HPFRCCs). For this purpose, slender HPFRCCs and conventional concrete DRCBs with transverse reinforcement spacing of 110 mm, 250 mm, and 500 mm were made and tested. One HPFRCC DRCB specimen was made without transverse reinforcement for comparison purposes. This experimental study shows that the slender HPFRRCC DRCBs with transverse reinforcement spacing of 250 mm have almost the same strength and drift capacity as those of the conventional concrete DRCB with transverse reinforcement spacing of 110 mm, satisfying the requirement of American Concrete Institute ACI 318-14 (2014) building code.

Specific Fracture

This paper deals about behavior of fiber reinforced cement composite in dependence on the casting direction. Almost fifty concrete prisms of size 400 x 100 x 100 mm were cast; half of these were fiber reinforced concrete (FRC) and the other half was ultra-high performance fiber reinforced concrete (UHPFRC). Approximately one half of both mixtures was cast in horizontal direction and the other half vertically. It was found that the specific fracture energy of horizontally cast prisms was approximately 4,5 times larger for both materials than the vertically cast ones. Ultimate loads of FRC were very similar for both casting directions. Peak loads of the horizontally cast UHPFRC prisms were approximately 3 times larger than the vertically cast ones. This research confirmed that there is significant influence of the casting direction on the fiber reinforced concrete characteristics.
