Research on Fatigue Behavior of Concrete Beams Reinforced by Cold-Rolled Deformed Steel Bar 冷轧带肋钢筋混凝土受弯构件疲劳性能研究
The on-line measurement of the deformed steel bar's surface parameters is the key point not only to improve prodcts 'quality and productive efficiency but also to the realization of automatic contral. 对螺纹钢外型参量进行在线测量是保证产品质量,提高生产效率、实现自动控制的重要环节。
Experimental study of the bond behavior of the following three different types of prestressed reinforcements: spiral-groove steel wire, deformed steel bar and steel strand is carried out. 对3种不同外形的预应力钢筋螺旋肋钢丝、异形钢棒、钢绞线的粘结性能进行了试验研究。
The concrete beams reinforced by adequate cold rolled deformed steel bar have well resisting crack ability and ductility, and their fatigue lives increase remarkably. 受弯构件适当配置冷轧带肋钢筋不仅具有良好的抗裂性能和延性,而且其疲劳寿命也有显著的提高。
In recent years, round steel bar, deformed steel bar and helical rib steel wire for prestressed concrete are new kinds of high strength prestressed reinforcement. 预应力混凝土用光圆钢棒、异形钢棒及螺旋肋钢丝就是近年来开发的高强预应力钢筋新品种。
In order to solve the anchorage design problem in RPC members, the bond anchorage mechanism and bond anchorage strength of deformed steel bar are analyzed, which also provide the basis for the standard enaction for RPC. 分析了变形钢筋在活性粉末混凝土构件中的粘结锚固机理和粘结锚固强度变化规律,以解决活性粉末混凝土构件中钢筋的锚固设计问题,为活性粉末混凝土规范的编制提供依据。
