摘　　要：通过两个无粘结部分预应力扁梁柱节点的试验 ,研究了钢纤维在无粘结部分预应力扁梁柱节点中的作用。研究表明 :钢纤维可以改善无粘结部分预应力扁梁柱节点的破坏形态 ,提高其刚度、承载力、延性系数和耗能能力 ,减少节点核心区剪力筋的应变。因此 ,在设计中 ,当在无粘结部分预应力扁梁柱节点中掺入钢纤维时 ,可以减少节点核心区剪力筋的配量 ,以方便施工。Based on the experiment of two unbonded partially prestressed flat beam\|column joints,this paper studies the effect of steel fiber in the unbonded partially prestressed flat beam column joints.The study verifies that the destroy types can be better and the stiffness,strength and seismic resistance behavior can be improved and the strains of shear steel bars can be decreased when the steel fiber is added into the unbonded partially prestressed flat beam column joints.An advise is proposed that the amount of shear steel bars can be less when steel fiber is mixed in such joints in order to make construction easy.
