摘要
通过对低周反复荷载作用下高强混凝土框架节点及钢纤维高强混凝土框架节点试验,研究了钢纤维对高强混凝土框架节点延性性能和耗能的影响。结果表明,钢纤维对改善高强混凝土脆性大的弱点并提高节点延性具有明显的效果,在节点部分使用钢纤维混凝土,可大大减少核心箍筋以及梁的抗剪箍筋,使节点延性改善且便于施工,造价便宜。
Based on the experimental study of high-strength reinforced concrete frame joints and steel fiber reinforced high-strength concrete frame joints under low cyclic loading,it is analyzed that steel fiber influnces on ductility and energy of high-strength reinforced concrete. It is demonstrated that the steel fiber has better effects on improving the bride failure state and increasing the seismic ductility of high strength concrete joints. If steel fiber reinforced concrete is used in the joints ,the stirrup of the core of the steel fiber concrete frame joint has fewer stirrups and shear stirrups. This can not only improve ductility of frame joint and deal with the construction difficulties but also bring good economic benefits.
