대각보강된 프리캐스트 HPFRCC 커플링 보의 비선형 해석

다국어 초록 (Multilingual Abstract)

HPFRCC have recently been proposed as an alternative to concrete in coupling beams between shear walls. Ordinary reinforced concrete coupling beams for shear walls require heavy reinforcing details to provide stable behavior under seismic loading. The use of HPFRCC has been proposed in order to reduce the level of reinforcing required while maintaining or even improving strength, ductility and energy dissipation, in addition to improving damage tolerance. The purpose of this study is to assess the validity of modeling techniques for simulating the cyclic behavior of these HPFRCC coupling beams. Presented in this paper are results from nonlinear finite element analyses performed on two of the specimens containing diagonal reinforcing. In the finite element model, the mode of failure wasthe same, with opening of the main diagonal crack following compression failure of the concrete and HPFRCC. Also, The specimens was performed and showed that for shear controlled coupling beams, the pseudo-strain hardening behavior of HPFRCC materials can lead to large increases in strength before shear failure occurs.
