Reinforced concrete members with high-performance steel shear reinforcement

与传统的变形钢筋相比，ASTM A1035钢具有更高的可用强度，可以显著减少混凝土构件中的钢筋堵塞。 此外，与其他高强度材料相比，这种材料的冶金学差异提供了改善的延展性和降低的腐蚀敏感性。 这些有利条件使ASTM A1035钢成为桥梁和其他预制构件的可行选择，其中强度，延展性和耐久性都是主要设计考虑因素。 由于ASTM A1035钢筋的机械性能与传统钢筋相比存在差异（即规定强度更高、缺乏屈服平台、粘结特性得到改善），因此必须完成设计方法的验证和增强，并且必须确定钢筋中最大可用应力的当前限值。

The higher available strength of ASTM A1035 steel compared to traditional deformed rebar offers the potential for significantly reduced reinforcement congestion in concrete members. Moreover, differences in the metallurgy of this material provide improved ductility and reduced corrosion susceptibility compared to other high strength materials. These favourable conditions make ASTM A1035 steel a viable option for construction of bridge girders and other precast members where strength, ductility and durability are all primary design considerations. Due to differences in the mechanical properties of ASTM A1035 reinforcement compared to traditional reinforcement (i.e. higher specified strength, lack of yield plateau, improved bond characteristics), validation and enhancement of design methodologies must be completed and current limits on the maximum useable stress in the reinforcement must be established.
