Abstract

<p>Before 1950, steel bridges were basically connected by rivets. Most of the steel bridge has been replaced due to aging or corrosion. However, many rivet bridges are still being in service; some of the rivets might be corroded and loosen due to the paint coating's deterioration. The riveted bridge has to repair by replacing the corroded rivets with high-strength bolts for friction connection. However, the slip coefficient of riveted joint surfaces with red lead treatment is not specified. In this study, specimens cut out from a 90-year-old riveted bridge's joint section and evaluated the riveted joint surface's aging condition by microscope observation and elemental analysis. The slip and pressure distribution tests are also conducted to investigate the slip coefficient and pressure distribution of riveted joints' surface. It is found that the joint surface is not flat, the average slip coefficient is 0.274, and the −2𝜎 is calculated to 0.169.</p>
