预应力CFRP板加固混凝土桥梁研究与应用
STUDY AND APPLICATION OF LARGE-SCALE CONCRETE BEAMS STRENGTHENED WITH CFRP LAMINATE
摘要
Abstract
Large scale concrete beams were strengthened by prestressing CFRP laminate with the special me chanical stressing and anchoring tools, then the strengthened beams were carried out to failure under the monotone load. On the basis of experimental results, the prestressing technique is used to rehabilite a railway simply-suppor ted concrete bridge. The strengthened effect is good through testing the change of crack width and the mid-span de flection.关键词
