Abstract:The corridors of a cement factory were damaged in different levels after the earthquake happened in May 12th, 2008 in Jiangyou, In addition, with the structure gradually aging, members cracking, steel corrosion, concrete spalling and carbonation, serious security issues were caused in production. Based on the detection and appraisal results of the concrete corridors, reinforcement measures analysis were made for the damage structure and structure members. Take into account the treatments of seismic joints, damaged structural members, strengthening of structural integrity and conformation measures, the detailed reinforcement measures were presented as reference design for similar structures after earthquake.
