某排架结构厂房的检测鉴定及加固

通过对某单层单跨双坡排架结构厂房进行现场检测、结构计算和分析研究,发现其主要问题为钢筋混凝土柱的承载能力不满足规范要求,确定其可靠性为四级,已不能正常使用,须立即采取加固措施。经多方案比较,最终采用外包钢加固技术对混凝土柱进行了加固,并对现场一些缺陷进行了修复处理,取得了良好的效果。经过处理,厂房的可靠性被鉴定为一级,满足了正常使用要求,避免了厂房的拆除重建,节省了大量的社会资源。

DETECTION APPRAISAL AND STRENGTHENING OF A BENT FRAME STRUCTURE PLANT

The site detection,structural calculation and analysis of a single floor and span double way gradient bent frame structure plant were carried out,then the major problem was discovered that the carrying capacity of the reinforced concrete column dissatisfy the code requirement,and the reliability was confirmed to be class 4,which could not be used normally,so the measures should be taken to strengthen the plant. Through many scheme's comparing,steel-encased strengthening technique was adopted to reinforce the concrete column,some defects were repaired,and excellent strengthening effect was got. After disposing,the plant's reliability was confirmed to be class l,which can satisfy the normal use requirement,and the plant avoided rebuilding,and abundant social resources were saved.
