  • Compression bearing capacity of rolled H-beam end with partial cross-section loss

説明

<p>Damages due to corrosion occur at girder end of rolled H-beam bridge which is managed by municipalities of Japan. Necessity of their repair or renewal should be rationally judged by their remaining strength under limited budget of municipalities. This study aims to experimentally clarify remaining strength of rolled H-beam end with partial cross-section loss at the web and end stiffener. For this reason, residual stress distribution of the web and end stiffeners, which affects the ultimate strength, are shown based on the measurement. Also, the effect of volume loss amount on the ultimate behavior and strength are exhibited by compression test. Moreover, applicability of existing estimation equation for I-shaped girder end with volume loss due to corrosion into rolled H-beam end are demonstrated.</p>
