摘要
以震后受损的单排双连体圆形钢筋混凝土筒仓结构为例,介绍了钢筋混凝土筒仓结构检测鉴定过程。现场发现筒壁底部多处出现交叉斜裂缝,主要是由地震作用引起;其他结构参数检测及结构承载力复核结果满足要求,综合评定该筒仓结构的可靠性等级为三级,并提出了相应处理措施。
On the basis of the earthquake damaged single row double connected circular reinforced concrete silo structure,appraisal process of reinforced concrete silo structure is introduced.It was found that there were many cross inclined cracks at the bottom of the silo wall,which were mainly caused by the earthquake.The results of other structural test items and the review of structural load-bearing capacity meet the requirements.The reliability level of the silo structure is evaluated as level three,and the appropriate treatment measures are provided.
