具有抗震弹性的结构很有吸引力，因为任何损坏都可以快速修复，并且结构可以很快重新使用。提出了一种新型的全装配式梁柱节点。采用超高性能混凝土（UHPC）节点和摩擦阻尼器连接梁柱。所有部件均采用螺栓连接，便于快速更换。在地震作用下，变形主要集中在摩擦阻尼器上。由于UHPC节点截面高度小，抗裂性好，因此节点几乎不受破坏。采用商用有限元软件ABAQUS进行数值分析，得到梁柱节点的抗震性能。研究了UHPC节点各参数和摩擦阻尼器的影响。分析结果表明，梁柱节点具有良好的受力性能和损伤容限。对梁柱节点的设计提出了详细的建议。
Seismically resilient structures are appealing because any damage can be quickly repaired and the structures can soon be reoccupied. In the present paper, a novel fully-prefabricated beam to column connection was proposed. A composite ultra-high-performance concrete (UHPC) joint and a friction damper were employed to connect a beam to a column using the proposed joint. All components were connected using bolts, which are convenient for quick replacement. Under earthquake excitation, deformation was mainly concentrated in the friction damper. The composite UHPC joint sustained little or no damage, owing to its small section height and excellent crack resistance. Numerical analyses were conducted using commercial finite element software, ABAQUS, to obtain the seismic performance of the beam to column connection. The effects of various parameters of the composite UHPC joint and the friction damper were investigated. According to the analysis, the beam to column connection delivered satisfactory mechanical characteristics and damage tolerance. Detailed design suggestions for the beam to column connection are provided.
