摘要
预制装配式框架梁柱节点通过后张预应力和非预应力插入钢筋混合式连接是由美国PCI学会提出的一种新型抗震节点形式。对该类节点的抗震性能进行了非线性有限元分析,对比研究了该预制装配式节点与现浇节点的承载能力、滞回性能及耗能能力等,可供相关研究参考。
Precast Beam-column joint assembled with post-tensioning presented by American PCI is a new joint with excellent seismic behaviors. The beam and column are assembled with post-tensioning and mild steel reinforcements which are inserted in the hole of the precast beam and column. The seismic behaviors of the joints are analyzed with nonlinear finite element analysis and the capacity, the hysteresis behaviors and the energy dissipating ability of the precast joint are compared with those of the cast-in-situ joint.
