Seismic behavior of a replaceable artificial controllable plastic hinge for precast concrete beam-column joint

Popis výsledku v původním jazyce

To promote and effectively control precast structures’ seismic performance, a novel bending-shear decoupled prefabricated beam-column joint with a replaceable Artificial Controllable Plastic Hinge (ACPH) was proposed in this paper. The ACPH was composed of two energy dissipation systems with energy-dissipation plates for bearing the bending moment and a connection system for bearing the shear force. To explore the seismic behavior of joint affected by ACPH, hysteresis tests of two beam-column joints with ACPH and one cast-in-situ beam-column joint were carried out. It found that the ACPH can significantly affect the failure mode compared with cast-in-situ specimen while offering excellent hysteresis behavior, sufficient ductility, and superior energy consumption capacity. Even if half of the energy-consuming system fails, the ACPH still maintains remarkable seismic performance except for reduced bearing capacity. Although only the location of the ACPH has been changed, the crack development, skeleton curve, and energy consumption performance have all undergone significant changes. The bearing capacity of the ACPH specimen was enhanced with the distance between ACPH and columnnsurface increasing, while other seismic performances were affected at different levels. Besides, the calculation model and formula of yield bearing moment capacity for the ACPH were proposed.
