摘　　要：冷轧带肋钢筋是一种实用的高效建筑钢材，是国家科委和建设部的重点推广应用项目．对其混凝土构件的刚度、裂缝等问题的研究工作开始不久．本文通过对面已置冷轧带肋钢筋混凝土构件（梁、板）进行试验研究，针对裂缝开展的机理及裂缝宽度的计算等问题做了初步探讨，为工程应用提供科学依据．Cold - rolled ribbed steel is a functional, new - fangled and high efficient building material. The research of the rigidity,crack width and other problem of the structural components with such materials have just been started. By means of the experimentalreseach of the reinforced concrete structural components with cold-rooled ribbed steel REBARS,a preliminary study about the mechanism of the growth of the crack and the ca1culation of the width of the crack are put forward in this paper. These can be used as the scientific bases in engineering applications.

关 键 词：冷轧带肋钢筋 裂缝宽度 钢筋混凝土 梁 板
