| Abstract: |
Stainless steel is a high-performance alloy with superior corrosion resistance compared to carbon steel. By applying stainless steel to corroded areas of a steel bridge, durability can be substantially improved. Our objective is to create a steel bridge that integrates hybrid structural components, which are composed of a combination of welded stainless steel and carbon steel, used to reinforce steel girder ends or their lower sections. Specifically, I-girder ends mainly subject to shear loads are our primary focus for corroded sections. This study examines the ultimate shear strength of welded steel girders comprised of stainless and carbon steel through load tests and numerical analysis. As a result, the ultimate strength of a hybrid girder can be assessed using a design equation for a homogeneous girder made of carbon steel by the Basler equation or an ultimate shear strength curve for stainless steel plates proposed in previous research in Japan. |
