高强钢筋的合理选择及应用

通过分析混凝土结构对钢筋性能的要求,提出了设计时钢筋选择的原则。在对比新规范与原规范的基础上,分析了规范修订中新增加有关高强钢筋内容的背景。结合高强钢筋的推广应用,根据目前我国现有的钢筋品种,给出了混凝土结构设计中优化选择钢筋的建议,提出了纵向受力钢筋、延性配筋(包括抗震钢筋)、横向钢筋、基础配筋及构造钢筋的正确选择方案(钢筋牌号及强度等级)。

Selection and Application of High Strength Reinforcement

Based on the request to reinforcement performance in concrete structure design,this paper proposes the principle of reinforcement selection.Comparing the new standard with the original standard,the paper analyzes the background of high strength reinforcement in standard revision.Combining with the application and varieties of high strength reinforcement in our country,it puts forward the selecting advises of reinforcement for concrete structure,including the selection plan for longitudinal reinforcement,stretchability reinforcement（including anti-seismic reinforcement）,transverse reinforcement,reinforcement for foundation and construction reinforcement.
