Theoretical and Experimental Study of the Behaviour of R.C.Columns Strengthened with Glued Steel Plates

摘要

本文论述的是用粘贴钢板加固的钢筋混凝土柱的强度计算 问题。由于多种原因，诸如冲击加载、循环加载、静力超载、干缩、持续荷载下的徐变、温度应力、钢筋腐蚀等，混凝土结构经常会产生结构性和非结构性的开裂。用试验方法研究了粘贴钢板法对钢筋混凝土结构柱的有效性，并作了详细的描述。试件有两类：(1)普通钢筋混凝土柱(短柱和细长柱)，对小偏心和大偏心荷载均试验到破坏；(2)粘钢加固柱(短柱和细长柱)，对小偏心和大偏心荷载均试验到破坏。将根据设计规范和作者建议的方法得到的强度计算结果与试验结果作了比较。试验结果表明，粘贴钢板方法能提高柱子构件的强度。发现在柱子表面垂直于荷载轴线粘贴钢板能提高这种方法的有效性。粘钢方法适用于修复、加固已有的结构，也适用于建造新的结构。
