Abstract
This research proposed a calculation method for the deformation of the frame system with the artificial controllable plastic hinges (APHF). The lateral deformation amplification coefficient was introduced to regulate the deformation value of APHF. Based on the equivalent system method, the relation between the rotational stiffness of the artificial controllable plastic hinge and the lateral deformation amplification coefficient was analyzed. According to the structural performance requirements, the rotational stiffness limit of the artificial controllable plastic hinge can be obtained to avoid the APHF deformation exceeding the demand limits. Based on the APHF experiment, the APHF model was developed using Opensees. Subsequently, the dynamic response analysis was performed to further explore the deformation mechanism of APHF. The seismic response analysis results indicated that the inter-story drift of APHF was more evenly distributed, which avoided the formation of vulnerable structural layers, compared with RC frame. The artificial controllable plastic hinge effectively reduced the base shear of the frame structures.
