STUDY ON STRENGTHENING DESIGN AND CONSTRUCTION TECHNOLOGY FOR LOW STRENGTH CONCRETE OF A FRAME STRUCTURE
-
摘要: 介绍采用灌浆料置换框架梁柱部分截面的低强度混凝土及碳纤维布加固梁柱节点的方法。置换法的运用,得力于将已建框架结构采取措施临时转换为砖混结构及框架柱中钢筋骨架焊接成格构柱,共同传递荷载的综合施工方案和技术措施。Abstract: It is introduced a method of using grout to replace low strength concrete of partial section of frame beams-column and strengthening beam-column joints of frame structure with carbon fiber. Plan and technical measures of transfering load together by changing existing frame structure to masonry structure and welding steel skeleton of frame column into lattice column, cause replacing method successfully applied. This is a typical case of achieving the design by construction technology.
