보강상세에 따른 프리캐스트 HPFRCC 커플링 보의 내진성능
Effect of Reinforcement Details on the Seismic Performance of Precast HPFRCC Coupling Beams
- 발행 : 2005.11.01
초록
In order to effectively resist seismic loads, coupling beams must be sufficiently stiff, strong and posses a stable load-deflection hysteretic response. This paper reports experimental data on the seismic performance of precast HPFRCC coupling beams with variable details. Precast HPFRCC coupling beam was tested to evaluate their failure modes. shear behavior, micro crack pattern and energy dissipation. Based on the experimental results, precast coupling beam with diagonal and rhombic details offer greater performance and ductility than coupling beam with normal detail.
