Bending performance of connection-corroded welded hollow spherical joints

Indoor swimming pools are a typical aggressive environment in which long-span steel structures are prone to corrosion, especially in the connection position of joints. In order to evaluate the impact of the corrosion on the mechanical properties of joints, a corrosion test of Q235 steel in a swimming pool environment was carried out for 48 and 72 months respectively. The surface pitting distribution of the corrosion specimens was measured and...
