一、前言目前有各种各样使用纤维的混凝土复合材料,使用的方法也多种多样。常用的纤维有钢纤维、玻璃纤维、碳纤维、聚乙烯纤维等等,其中在现今建设中作为结构材料使用较多的是钢纤维,大多是在混凝土中散置短的钢纤维制成钢纤维补强混凝土(steel fiber reinforc-ed concrete,缩写为 SFRC)。对 SFRC 的研究开始于1963年 Romualdi 等发表的文章。其理由是:过去认为混凝土的 I. Preface There are various kinds of concrete composite materials that use fiber at present, and the methods used are also varied. Commonly used fibers are steel fiber, glass fiber, carbon fiber, polyethylene fiber and so on. Among them, steel fiber is mostly used as structural material in present-day construction, most of them are made of steel fiber filled with short steel fiber dispersed in concrete Strong concrete (steel fiber reinforc-ed concrete, abbreviated SFRC). The study of SFRC began in an article published in 1963 by Romualdi et al. The reason is: in the past that concrete
