Analysis on the Behavior of Modified DDC, Precast Beam-Column Concrete Connectors for Apartments
- 발행 : 2005.11.01
초록
Four precast concrete beam-column connectors for the apartment buildings were considered to develop a modified model which was adapt to domestic construction conditions from the DDC(Dywidag Ductile Connectors) of Germany. Special H-shape steel were used to decrease the width of column and beams for the construction of external frames of apartments. It was found that the DDC had high joint strength and ductility, however failed in x-shape crackings in the columns. The modified one showed better behaviors in tests because they did not show critical column crackings at failure. The test result of modified one with grouting were compared to that of the one without grouting within the duct. The one with grouting showed higher strength and ductility in failure than that without grouting.
