摘要：
I-girders with high webs are widely used in ship and ocean structures. According to Eurocode 3, specifications for ultimate shear resistance of steel plate girders do not take full account of impacts due to elevated temperatures. In this paper, ultimate shear resistances of I-girders with high webs were computed by nonlinear implicit dynamic method and validated with experiment results. Aiming at non-uniform temperature situations, this paper considered three different temperature distributions and detailed the inadequacy of Eurocode 3. An improved method to predict the shear resistance of steel plate girders at non-uniform elevated temperatures was also presented, which provides a reference for structural design and safety assessment of I-girders under shear load at elevated temperatures. © 2020, Editorial Board of Journal of Ship Mechanics.
