中美建筑用钢筋标准及应用对比分析

Comparative Analysis on Construction Rebar Standards and Application Between China and U.S

我国正处于工业化和城镇化快速发展时期,同时,随着与国际接轨的步伐加快,建筑用钢筋不仅要满足国内建设市场的需要,还要积极加入国际市场的竞争,满足国际市场的需要,这对钢筋的性能、质量提出了更高的要求。本文首先介绍中美两国建筑用钢筋主要产品标准和应用标准的相关内容,阐述了两国建筑用钢筋的发展情况。通过比较分析,指出两国标准在钢筋强度等级设置、应用要求、抗震性能、机械连接和锚固等方面的异同。在此基础上,借鉴美国建筑用钢筋的发展经验和做法,对我国加快建筑用钢筋品种优化与更新换代提出可行建议。

China is currently in a rapid development period of industrialization and urbanization. Mean while, with the pace of internationalization, products of building rebar are required not only to meet domestic needs, but also to be competi- tive in international market. Therefore, construction rebars with higher quality and performance is requested by the industry. In this paper, the main component and development of rebar＇s primary product standards and application standards between China and U. S. are reviewed. The similarities and differences in grades setting, requirement of application, seismic perform- ance, mechanical connection and anchoring between the standards are comparatively analysed as well. Finally, the analysis results in several feasible proposal helpful for type optimization and upgrade of construction rebar by referencing the advanced experience and practice of U. S.
