Lack of consistency between the drawings and the executed condition, corrosion of structural members, structural problems of the shed’s roof, lack of cross-connection between the two frames, low capacity in some members, poor connections in the structure, the bearing capacity problem in the foundation, problems of water leakage into the foundation soil. Corrosion in the drainage paths is one of the main problems of this steel structure and due to the fact that this hall is a place where a lot of sellers and buyers commute, it is not safe enough, and therefore not paying attention to this structure’s problems can cause financial and human losses.<\/p>\n<\/div><\/div><\/div>

\n

After checking the non-compliance of the mentioned structure with its executive drawings and removing the damages, non-destructive corrosion tests, measuring soil strength under the foundation, weld inspection, base metal thickness measurement and paint and coating inspection were performed, and after modeling the necessary measures were taken to eliminate the defects and problems of the mentioned structure. These measures include rust removal of corroded parts and using GFRP anti-corrosion coating for them, installation of braces and struts in the required places, installation of strengthening plates and braces for members with low capacity and modification of joints with poor resistance, strengthening the bearing capacity of the foundation by planting bars and additional foundation, creation of geomembrane waterproofing for floors and modification of drainage paths using a galvanized plate with GFRP coating.<\/p>\n<\/div><\/div><\/div>

\n

By performing corrective solutions and retrofitting, including strengthening members and joints, creating corrosion coating for members, modification of drainage paths, strengthening the foundation and insulation of floor surfaces, the lifespan of this structure has increased to an acceptable level and the structure is protected against environmental conditions and various destructive factors.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
